PX 3.0: live migration (node to node) freeze VM on different hardware

[dea]

Hello !

I've a problem on PX 3.0 (I know, it is not the latest version) on migration (node to node) on nodes with different hardware (processors).

The cluster has three nodes, node 1 and node 2 are identical and migration works fine. When I try to migrate to node 3, migration works but the VM (after migration) freeze with the CPU on 100%

Proxmox 2.3 works fine on the same hardware and migrates correctly on nodes 3.

Is a known issue?

Very thanks

Luca

different processors ? amd vs intel ?

what cpu model do you use for your vms ?

different processors ? amd vs intel ?

No.
On Node 1-2: Intel Xeon E5-2603 (2 socket)
On Node 3: Intel Xeon E5345 (2 socket)

what cpu model do you use for your vms ?

KVM64 (default)

I've tried on several VM... freeze on 100% CPU after migration vs Node 3 (node1 <> node2 all ok)

What CPU is on node2?

Does it make a difference using qemu64 in stead of kvm64?

On Node 1-2: Intel Xeon E5-2603 (2 socket)
On Node 3: Intel Xeon E5345 (2 socket

I can try qemu64 ... and/or update to PX 3.1 (include several bugfix)

are you sure that the pve-qemu-kvm package is at the same version on both nodes ?

and also the same kernel ? (#uname -a to be sure)
