issue on moving Ubuntu Server VMs from one server to another

Hi all,

we run proxmox 5.3-5 on a cluster of 5 servers and the QEMU Agent is installed on every VM.

We noticed whenever we move an Ubuntu Server VM from one server to another, the VM would turn totally unresponsive and from the console we would read this:
image-2018-12-28-12-50-46-998.png

Kernel Panic.
The only way to restore the VM is to reboot it.

Usually Windows, CentOS or SLES VMs have very little or no problem at all with the migration task, but the Ubuntu Server, no matter which version we're running, is always ending in a Kernel Panic.

How could we solve this?
 
The screenshot is not attached - please provide it (or a text-dump if possible!)
 
* Which CPUs do you have in your PVE-nodes?
* What CPU(s) is configured for the Ubuntu Server VM? (please post the VM's config - `qm config $VMID` (anonymized if needed))
 
* Which CPUs do you have in your PVE-nodes?

PVE-node 1) 24 x Intel(R) Xeon(R) CPU X5650 @ 2.67GHz (2 Sockets)

* hmm - which versions of pve are you running (`pveversion -v`)?
* which version of ubuntu is the guest, and which kernel is it running?
* Try updating everything to the latest available versions!
You could try the following 2 options to narrow the issue down some more:

* change the guest's cpu-type to host - and migrate between node 1 and node 5 (same cpu)
* try booting some other kernels on the Ubuntu guest and see if the issue persists
* try booting some other kernels (on both nodes) and see if the issue persists
 
* hmm - which versions of pve are you running (`pveversion -v`)?

I can't on this one and on many others, but I'll create a new Ubuntu VM for this tomorrow.
Then, I'll try your tips.

Thanks!
 
Hello, I'm back

so, following your directions I created a new Ubuntu Server VM, latest version available:

Originally the config was like this:
Code:

vmgenid: b93f0794-9aba-4285-9de0-8619de741577

and I changed it to this:
Code:

bootdisk: scsi0
cores: 1
cpu: host

Then, I migrated the VM 226 from PVE01 to PVE6 (both running 24 x Intel(R) Xeon(R) CPU X5650 @ 2.67GHz (2 Sockets))

This is a new error, probably related to the new CPU configuration (host). Usually the task would end just fine, then we would get a Kernel Panic.
 
Hi,

here we go with a fresh new KP.

so, we did more tests moving a VM between those nodes:

PVE01) 24 x Intel(R) Xeon(R) CPU X5650 @ 2.67GHz (2 Sockets)
PVE02) 16 x Intel(R) Xeon(R) CPU E5620 @ 2.40GHz (2 Sockets)
PVE04) 16 x AMD Opteron(TM) Processor 6220 (2 Sockets)

if the VM CPU type is: KVM64

moving the VM from INTEL nodes to AMD nodes: KP
moving the VM from AMD nodes to INTEL nodes : KP
moving the VM between AMD nodes: no KP
moving the VM between INTEL nodes: no KP

if the VM CPU type is: HOST

moving the VM from INTEL nodes to AMD nodes: KP
moving the VM from AMD nodes to INTEL nodes : KP
moving the VM between AMD nodes: no KP
moving the VM between INTEL nodes: KP
In fact, we have Xeon(R) CPU X5650 and Xeon(R) CPU E5620, and between the 2 Xeon(R) CPU X5650 we also have a KP probably because one node is configured to let NestedVirtualization, and the other one is not.

At this point, I believe Proxmox is not able to handle a migration between nodes running different CPUs.

That is true. Live migrations at least do not work if cpu differ.
If you do migrations in that situation, use as CPU the default KVM64. Then you can migrate to nodes running different CPU:s.
After migrations are finished, you can change the CPU back to host.
 
It's a bug. Proxmox team knows about it and won't acknowledge or do something about it. Live migration worked fine in 5.0 and then broke after that.
See https://forum.proxmox.com/threads/live-migration-broken-for-vms-doing-real-work.49380/ and https://bugzilla.proxmox.com/show_bug.cgi?id=1660

Try this:
Code:
qm set **VMID** --args "-cpu 'kvm64,+ssse3,+sse4.1,+sse4.2,+x2apic,+aes,+sep,+movbe,+lahf_lm,+kvm_pv_eoi'"
and shut down and start up your VM.

For me live migration then works even between different CPUs and CPU vendors.
