3. Export VMs from VMware

Shutdown VMs: Properly shut down the VMs on your VMware ESXi host before exporting them.

Export as OVF/OVA: Use VMware's export feature to create an OVF (Open Virtualization Format) or OVA (Open Virtual Appliance) file of your VM. This format is widely supported and facilitates easy import into Proxmox VE.

4. Import VMs into Proxmox VE

Upload OVF/OVA: Transfer the exported OVF/OVA files to your Proxmox VE server.

Import Using Proxmox Interface: Use Proxmox VE's interface to import the OVF/OVA files. During this process, you may need to adjust some settings, such as disk format or network adapters, to ensure compatibility with Proxmox.

5. Configure and Test

Adjust VM Settings: After importing, check the VM settings in Proxmox VE. Adjust CPU, memory, storage, and network settings as necessary to match the original VMware configuration.

Test VM Functionality: Before making the VM live, run thorough tests to ensure that it functions correctly in the Proxmox VE environment.

6. Go Live with Minimal Downtime

Plan the Cutover: Choose a time for the final switchover that has the least impact on your operations. Inform relevant stakeholders about the scheduled downtime.

Monitor the Transition: Keep a close watch on the VM's performance after going live on Proxmox VE. Address any issues immediately to minimize downtime.

7. Post-Migration Cleanup

Decommission VMware Setup: Once you’re confident that the VMs are stable on Proxmox VE, you can begin the process of decommissioning the old VMware environment.

Review and Optimize: Regularly review the performance of your VMs on Proxmox VE and make optimizations as needed to ensure ongoing stability and efficiency.

Conclusion

Migrating your VMware VMs to Proxmox VE doesn’t have to be a disruptive process. With careful preparation, the right tools, and a well-executed plan, you can achieve a smooth transition with minimal downtime. This guide provides a straightforward approach to help you navigate the migration process, ensuring that your virtual machines continue to operate seamlessly in their new environment.

If It's a Hack and It Works, Is It Really a Hack?

I have a couple servers at home — one running Proxmox VE and one running Proxmox Backup. I use the VM server when I need to spin up a development environment, for running the odd game server, serving files locally, running Home Assistant, etc. I also like to donate spare cycles to Folding@Home. The backup server of course is in case I do something stupid on the VM server.

There's just one problem with that. My second-hand 8-year-old dual-Xeon server runs hot.

It was too much to keep running in my home office. Between the two servers, my desktop, and my work laptop, I was regularly seeing ambient temperatures around 26°C. It was just too warm for comfort.

Last summer I moved my network gear and the two servers into the front coat closet. This was great for me working in my home office, but not so great for my servers. Despite adding a passthrough vent to the closet door and a vent fan to the ceiling, the closet was still consistently in the 26°-30°C range.

The ideal solution would probably be to use an enclosed server rack and run an exhaust vent up from the top. Unfortunately, rack-mount server cases are expensive, enclosed racks are very expensive, and my closet is too small for that anyway.

So I hacked together a solution.

I built a frame out of some cheap 1x2 lumber and wrapped a piece of thin sheet steel around the sides to make a crude plenum. On top, I added a 10x6 register box with a semirigid vent hose coming out of it. This gives me a guide for drawing air out of the servers and guiding it up to the vent fan in the ceiling.

To help things along, I added a 120mm fan inside the register box. But not some whisper-quiet Noctua. This is (if the Amazon listing is to be believed) a 5000 RPM, 210 CFM monster of a fan. It's loud, but moves a lot of air.

Too loud in fact. Its droning could not be silenced by any mere closet door. I had to add a PWM fan speed controller to calm it down. It's a cheap unit from Amazon, but it came with a temperature probe and it has a configurable operating range.

The result? Where previously the entire closet was consistently above 26°C, now it's staying around 23°. There is a difference of 5°C between ambient in the closet and the air inside the exhaust duct, so it is doing its job of redirecting the hot air from the servers.

I call that a successful hack.

How to Ensure Reliable Backups for Your Proxmox VMs

Ensuring reliable backups for your Proxmox virtual machines (VMs) is critical to protecting your data and maintaining business continuity. Here’s a guide to help you set up and maintain dependable backups for your Proxmox environment.

1. Plan Your Backup Strategy

Determine Backup Frequency: Assess how often you need to back up your VMs based on the importance of the data and the acceptable recovery point objective (RPO).

Choose a Backup Destination: Decide where your backups will be stored—this could be a local storage server, NAS, or cloud storage. Ensure your storage solution is reliable and secure.

2. Use Proxmox’s Built-in Backup Features

Snapshot Backups: Proxmox VE allows you to take snapshots of VMs. Snapshots are quick and can be scheduled, but remember they are stored on the same storage as the VM, so they’re not a full backup solution.

Full Backups: Use Proxmox’s backup tool to create full backups of your VMs. This method is more comprehensive than snapshots and ensures you have a complete copy of your VM data.

3. Automate Your Backups

Set Up Backup Schedules: Automate backups using Proxmox’s built-in scheduling feature. Regular automated backups minimize the risk of human error and ensure that your data is consistently backed up.

Use Backup Tools: Consider using third-party tools like NAKIVO Backup & Replication, which can offer advanced features like incremental backups, compression, and encryption.

4. Test Your Backups Regularly

Perform Regular Restore Tests: Regularly test your backups by restoring them to ensure that they’re functional and that you can recover your data when needed. A backup is only as good as its ability to restore.

Validate Data Integrity: After restoring, verify the integrity of the data to ensure it matches the original and is free from corruption.

5. Implement Redundancy

Use Multiple Backup Locations: Store backups in multiple locations to protect against site-specific disasters. For example, maintain copies on both local storage and cloud storage.

Geographic Redundancy: Consider geographic redundancy, where backups are stored in different physical locations to protect against regional disasters.

6. Ensure Security

Encrypt Your Backups: Protect your backups with encryption, especially if storing them off-site or in the cloud, to prevent unauthorized access.

Access Controls: Implement strict access controls to ensure that only authorized personnel can access or restore backups.

7. Monitor Backup Processes

Set Up Alerts and Notifications: Configure alerts for backup failures or missed schedules. Monitoring tools can help you quickly identify and address issues.

Regular Audits: Conduct regular audits of your backup processes to ensure compliance with your backup strategy and to identify any areas for improvement.

Conclusion

Reliable backups are the cornerstone of data protection in any virtual environment. By planning a solid backup strategy, automating the process, regularly testing your backups, and ensuring security, you can safeguard your Proxmox VMs against data loss and minimize downtime. Investing time and resources into your backup process will give you peace of mind, knowing that your virtual machines are well-protected.
