I find it pretty devastating that Skinny Puppy’s hanDover has become nearly lost media at this point; like not just “not on streaming services” but nearly inaccessible at all, out of print, not even fully uploaded to YouTube, 4 copies on Discogs and 5 on Amazon averaging like $30. I’ve always found the lukewarm reception this album received genuinely mind blowing. I guess it didn’t sound enough like old school Skuppy for people but it’s so special. I think it’s one of Skuppy’s more genuinely difficult albums and I mean that with love, I think Skuppy should be difficult. It has an atmosphere unlike any other album from them or anyone else; it’s such a deeply dreary album. I think dreary is the most apt word. It’s just dismal and gloomy and grey. It kinda meanders through this smoggy dreamlike stupor through each track with this really distinct sharp prickliness despite its more slow atmospheric sound… Ovirt into Cullorblind into Wavy into Ashas is such an unrelentingly moody introduction, with the final song of the set being explicitly about the grief of losing a recently deceased friend. The song above, Gambatte, comes right after, and to give an idea of how low energy the album skews this is one of the faster tracks on there. Gambatte is actually one of my favorite Skuppy songs of all time and its inaccessibility makes me want to rip my hair out. It’s got such a weird muted whimsy to it. It seems like even the band has distanced themselves from this album, with it being the only one of their mainline LPs to not have a single song on the set list of the Final Tour. I know the behind the scenes was difficult and it’s part of what made the album itself so difficult, but I feel like it’s such a shame that it feels like it’s at risk being sort of forgotten.

nvm there was no translation on virtualbox website or in oracles docs but prank theres a pdf showing up in google search in downloads.virtualbox.org even though idek where in virtualbox.org i could access that translation

found qemu, utm, both are translated and im going to set something on fire

i found ovirt and it seems to not be translated but maybe theres a fucking translation somewhere who the fuck knows

rage hatred suffering

i chose a text to translate for the computer science translation class and the teacher said there should be no translation available so i checked and there was none and she approved my text. i sent my translation yesterday and today she replied and said theres a translation. that fucking page was translated since the last time i checked it like. 2 weeks ago ???

so now i found another text (probably harder to translate too) and im looking everywhere before sending it to her, like if i find anyone translated oracle's vm virtualbox user manual somewhere i will obliterate them

Virtual Machines in Kubernetes? How and what makes sense?

Happy new year.

I stopped by saying that Kubernetes can run containers on a cluster. This implies that it can perform some cluster operations (i.e. scheduling). And the question is if the cluster logic plus some virtualization logic can actually provide us virtualization functionality as we know it from oVirt.

Can it?

Maybe. At least there are a few approaches which already tried to run VMs within or on-top of Kubernetes.

Note. I'm happy to get input on clarifications for the following implementations.

Hyper created a fork to launch the container runtimes inside a VM:

docker-proxy | v [VM | docker-runtime] | + container + container :

runV is also from hyper. It is a OCI compatible container runtime. But instead of launching a container, this runtime will really launch a VM (libvirtd, qemu, …) with a given kernel, initrd and a given docker (or OCI) image.

This is pretty straight forward, thanks to the OCI standard.

frakti is actually a component implementing Kubernetes CRI (container runtime interface), and it can be used to run VM-isolated-containers in Kubernetes by using Hyper above.

rkt is actually a container runtime, but it supports to be run inside of KVM. To me this looks similar to runv, as a a VM is used for isolation purpose around a pod (not a single container).

host OS └─ rkt └─ hypervisor └─ kernel └─ systemd └─ chroot └─ user-app1

ClearContainers seem to be also much like runv and the alternative stage1 for rkt.

RancherVM is using a different approach - The VM is run inside the contianer, instead of wrapping it (like the approaches above). This means the container contains the VM runtime (qemu, libirtd, …). The VM can actually be directly adressed, because it's an explicit component.

host OS └─ docker └─ container └─ VM

This brings me to the wrap-up. Most of the solutions above use VMs as an isolation mechanism to containers. This happens transparently - as far as I can tell the VM is not directly exposed to higher levels, an dcan thus not be directly adressed in the sense of configured (i.e. adding a second display).

Except for the RancherVM solution where the VM is running inside a container. Her ethe VM is layered on-top, and is basically not hidden in the stack. By default the VM is inheriting stuff form the pod (i.e. networking, which is pretty incely solved), but it would also allow to do more with the VM.

So what is the take away? So, so, I would say. Looks like there is at least interest to somehow get VMs working for the one or the other use-case in the Kubernetes context. In most cases the Vm was hidden in the stack - this currently prevents to directly access and modify the VM, and it actually could imply that the VM is handled like a pod. Which actually means that the assumptions you have on a container will also apply to the VM. I.e. it's stateless, it can be killed, and reinstantiated. (This statement is pretty rough and hides a lot of details).

VM The issue is that we do care about VMs in oVirt, and that we love modifying them - like adding a second display, migrating them, tuning boot order and other fancy stuff. RancherVM looks to be going into a direction where we could tnue, but the others don't seem to help here.

Cluster Another question is: All the implementations above cared about running a VM, but oVirt is also caring about more, it's caring about cluster tasks - i.e. live migration, host fencing. And if the cluster tasks are on Kubernetes shoulders, then the question is: Does Kubernetes care about them as much as oVirt does? Maybe.

Conceptually Where do VMs belong? Above implementations hide the VM details (except RancherVM) - one reaosn is that Kubernetes does not care about this. Kubernetes does not have a concept for VMs- not for isolation and not as an explicit entity. And the questoin is: Should Kubernetes care? Kubernetes is great on Containers - and VMs (in the oVirt sense) are so much more. Is it worth to push all the needed knowledge into Kubernetes? And would this actually see acceptance from Kubernetes itself?

I tend to say No. The strength of Kubernetes is that it does one thing, and it does it well. Why should it get so bloated to expose all VM details?

But maybe it can learn to run VMs, and knows enough about them, to provifde a mechanism to pass through additional configuration to fine tune a VM.

Many open questions. But also a little more knowledge - and a post that got a little long.

The performance of your virtualization environment is highly influenced by Network configurations. This makes Networking one of the most important factors of any Virtualized infrastructure. In oVirt/RHEV, there are several layers that make up Networking. The underlying physical networking infrastructure is what provides connectivity between physical hardware and the logical components of the virtualization environment. For improved performance, Logical networks are created to segregate different types of network traffic onto separate physical networks or VLANs. For example, you can have separate VLANs for Storage, Virtual Machine, and Management networks to isolate traffic. Logical Networks are created in a Data Center with each cluster being assigned one or more Logical Network. A single logical network can be assigned to multiple clusters to provide communication between VMs in different clusters. Each logical network should have a unique name, data center it resides on, and type of traffic in Virtualization environment to be carried by the network. If the virtual network has to share access with any other virtual networks on a host physical NIC, the Logical networks require setting a unique VLAN tag (VLAN ID). Additional settings that can be configured on a logical network include Quality of Service (QoS) and bandwidth limiting settings. Types of Logical Networks in oVirt / RHEV Segregation of traffic types on different logical networks is of paramount importance in any Virtualized environment. During oVirt / RHEV installation, a default logical network, called ovirtmgmt is created. This network is configured to handle all infrastructure traffic and VM network traffic. Example of infrastructure traffic is management, display and migration network traffic. It is recommended that you plan and create additional logical networks to segregate traffic. The most ideal segregation model is network traffic based on the type. Logical network configuration occurs at each of the following layers of the oVirt environment. Data Center Layer – Logical networks are defined at the data center level. Cluster Layer – Logical networks defined on the data center layer, and added to clusters be be used at that layer Host Layer – On each hypervisor host in the cluster, the virtual machine logical networks are connected and implemented as a Linux bridge device associated with a physical network interface. Infrastructure networks can be implemented directly with host physical NICs without the use of Linux bridges. Virtual Machine Layer – If the logical network has been configured and is available on hypervisor host, it can be attached to a virtual machine NIC on the that host. Main network types are: 1. Management Network This type of network role facilitates VDSM communication between oVirt Manager and oVirt Compute hosts. It is automatically created during oVirt engine deployment and it is named ovirtmgmt. It is the only logical network available post installation and all other networks can be created depending on environment requirements. 2. VM Network This is connected to virtual network interface cards (vNICs) to carry virtual machine application traffic. On the host machine, a software-defined Linux bridge is created, per logical network. The bridge provides the connectivity between the host’s physical NIC and virtual machine vNICs configured to use that logical network. 3. Storage Network It provides private access for storage traffic from Storage server to Virtualization hosts. For better performance, multiple storage networks can be created to further segregate file system based (NFS or POSIX) from block based (iSCSI or FCoE) traffic. Storage networks usually have Jumbo Frames configured. Storage networks are not commonly connected to virtual machine vNICs. Storage networks are configured to isolate storage traffic to separate VLANs or physical NICs for performance tuning and QoS 4. Display Network

The display network role is assigned to a network that carries display traffic (SPICE or VNC) of the Virtual Machine from oVirt Portal to host where the Virtual Machine is running. This type of network is not connected to virtual machine vNICs, it is categorized as Infrastructure network. 5. Migration network The migration network role is assigned to handle virtual machines migration traffic between oVirt hosts. It is recommended to use dedicated non-routed migration network to ensure there is no management network disconnection to hypervisor hosts during heavy VM migrations. 6. Gluster network The Gluster network role is assigned to logical networks that carries traffic from Gluster Server to GlusterFS storage clusters. It is commonly used in hyper-converged oVirt/RHEV deployment architectures. Creating Logical Networks on oVirt / RHEV With the basics on Logical Networks covered, we can now focus on how they can be created and used on the oVirt/RHEV virtualization environments. The creation of logical networks is done under the Compute menu in the Networks page. In this guide we’ll create new logical network called glusterfs for carrying traffic from Gluster Servers to GlusterFS storage clusters. Login in to the oVirt Administration Portal as admin user. Create new logical network While on Administration portal menu, click on Network > Networks > New button to create a new logical network. You’re presented with the New Logical Network dialog window. Fill in the fields under General tab – Data Center, Name Description and other parameters. You can uncheck VM network for infrastructure and Storage type traffic. Enable if logical network is used for virtual machine traffic If using VLAN, enable tagging and input VLAN ID If Jumbo frames are supported in your network, you can set custom number as configured at network level. Under Cluster you can check list of Clusters where created network will be available. Example for all clusters. Specific cluster Configuring Hosts to use Logical Networks In the previous section, we demonstrated how to create logical networks to separate different types of network traffic. In this section we describe the procedures needed to implement the logical networks on cluster hosts. By default, created logical networks are automatically attached to all clusters in the data center. For the logical network to be used in the cluster, it should be attached to a physical interface on each cluster host. Once this has been done the logical network state of the network becomes Operational. Login to the host and check available network intefaces $ ip link show 1: lo: mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 2: enp1s0: mtu 1500 qdisc fq_codel master ovirtmgmt state UP mode DEFAULT group default qlen 1000 link/ether 52:54:00:36:ad:26 brd ff:ff:ff:ff:ff:ff 3: enp7s0: mtu 1500 qdisc fq_codel state UP mode DEFAULT group default qlen 1000 link/ether 52:54:00:31:60:02 brd ff:ff:ff:ff:ff:ff From the output, the first interface enp1s0 is already used by ovirtmgmt bridge which is mapped to ovirtmgmt network. In the new creation, we shall use enp7s0 network interface. Assign logical network to an oVirt host Navigate to Hosts page, click the name of the host to which the network will be attached. Click the Network Interfaces tab to list the NICs available on the host. Open Host Networks setup window by clicking “Setup Host Networks“. Drag a logical network listed under “Unassigned Logical Networks” section to a specific interface row on the left. After dragging the network is assigned to the chosen interface. Click the pencil icon to set network parameters. From the window you can set boot protocol, IP address, netmask, and gateway when using static addressing. You can as well make network modifications from the optional tabs for IPv6, QoS, and DNS configurations.

Setting network role at cluster level The network created can be assigned a specific role under Clusters > Clustername > Logical Networks > Manage Networks Assign the role to the network you’re doing modifications for. Confirm your network is operational by testing connectivity between hosts / Virtual Machines and desired destination. Conclusion In this article we’ve been able to create a logical network in oVirt/RHEV virtualization platform. We went further and attached it to a physical network interface on one or more hosts in the cluster. Network configurations were made on the network with static network booting. DHCP can also be used as boot protocol. For infrastructure networks you must do configurations at the cluster level to indicate what type of traffic the network will carry.

CVE-2021-20238

It was found in OpenShift Container Platform 4 that ignition config, served by the Machine Config Server, can be accessed externally from clusters without authentication. The MCS endpoint (port 22623) provides ignition configuration used for bootstrapping Nodes and can include some sensitive data, e.g. registry pull secrets. There are two scenarios where this data can be accessed. The first is on Baremetal, OpenStack, Ovirt, Vsphere and KubeVirt deployments which do not have a separate internal API endpoint and allow access from outside the cluster to port 22623 from the standard OpenShift API Virtual IP address. The second is on cloud deployments when using unsupported network plugins, which do not create iptables rules that prevent to port 22623. In this scenario, the ignition config is exposed to all pods within the cluster and cannot be accessed externally. source https://cve.report/CVE-2021-20238
