Hello everyone:
I add a host to my proxmox cluster, Virtual machine migration to other hosts will not be a problem , Migration to a newly added host will cause a crash.

Thanks
 
Are the hosts the same Hardware/CPU?
What Hardware?
What Guest-Config?

I am still having issues with live migrating from a Dell PE640 to a Dell PE630. The reverse migration works just fine 630 > 640. So if this still an issue and how can it be worked around? I don't see any resolution in the bug reports. I did check the time on all servers in the cluster and they are in sync.

Both servers have the latest Dell BIOS and firmware version.

I am still having issues with live migrating from a Dell PE640 to a Dell PE630. The reverse migration works just fine 630 > 640. So if this still an issue and how can it be worked around? I don't see any resolution in the bug reports. I did check the time on all servers in the cluster and they are in sync.

Both servers have the latest Dell BIOS and firmware version.

The solution is to use a more recent kernel than the default 5.15 one on the source and target node(s): [1] [2] [3].
This would currently be the 6.2 opt-in kernel: [4], since all others in-between are EOL.

[1] https://bugzilla.proxmox.com/show_bug.cgi?id=4073#c60
[2] https://forum.proxmox.com/threads/p...on-linux-freeze-on-windows.109645/post-511185 (Again: 5.19 is EOL!)

@ejmerkel have you tried setting the CPU type of the VM to the older architecture of the two servers? Should be Broadwell in your case.

I'd be curious on what the official PVE recommendation is for Enterprise customers.

We don't discourage the use of the newer opt-in kernels. It is a valid choice in some setups, for example to get better support for newer hardware, getting some features that are only available in newer kernels, or in some situations it can lead to better stability.

edit: fixed sentence structure ;)

I tried setting the CPU type to Broadwell, stopping/starting the VM and then attempting to live migrate it. Unfortunately, the VM still locked up after the migration was complete.

Thne I would give a newer kernel a shot
 
I have the same problem between a Dell and a supermicro server when I do a live migration the VM crashes. Did the 6.2 kernel fix the issue?
