Hi Harald,
Thanks for your feedback.

we have the same problem with Debian 9 VMs, Debian 8 VMs migration is
fine.
After testing with only 1 core, as you suggested, migration works good.
We also upgraded to the latest Debian Kernel, I think it's 4.14.7,
with this version it seams to migrate stable between amd Opteron and
Intel Broadwell.
I just upgraded to latest kernel in stretch-backports, 4.14.13-1~bpo9+1,
and it has crashed again; so doesn't seem to have fixed our problem. I
tried twice just in case; near instant crashes both times ;)
We have seen the problem also with Ubuntu 14.04 kernel 3.16.0-30-generic...
Cheers
Eneko
bye
Harald

Hi,
I finally reproduced the problem with a Ubuntu 14.04.2 LTS VM, so
not a Debian 9-only problem.
Is there anything I to report this bug to Proxmox/upstream?

This kernel produced a lot of crashes (especially on windows),
even without any migrations.
Please retest with latest kernel.
Just updated the cluster:
# pveversion -v
proxmox-ve: 5.1-38 (running kernel: 4.13.13-5-pve)
[...]
The reported VM has migrated well for now, but I have seen a
similar crash with another two Debian 9 VMs this time. Other VMs
and SO/distros continue to work well, maybe there's a problem in
guest kernel. I continue to get crashes after Intel<>AMD
migrations, Intel<->Intel migrations work without issue (done
ten's of them during cluster upgrade).
Seems that only Debian 9 VMs with more than 1 cores are affected by
this problem. All 3 VMs had 2 or 4 cores. I changed the original
reported VM to 1 core, and seems not to crash now. NUMA is not
enabled.
I tried with previous Debian kernel (VMs are running now
4.9.0-5-amd64, previous is 4.9.0-4-amd64); and it crashes too.
I tried with a Ubuntu 14.04.02 LTS with 2 cores, but I'm unable to
reproduce the problem. Windows VMs also really seem unaffected.
Shall I report this to Debian kernel team?
Thanks a lot
Eneko
