[PVE-User] Proxmox 4.2 : Online Migration Successful but VM stops

[Dhaussy Alexandre]

Hello,

Here's the log of a successfull LIVE migration, but the VM stops afterwards and just before resuming. At this point, the service fails, and is restarted by HA services.

* sept. 30 14:13:12 starting migration of VM 463 to node 'proxmoxt32' (x.x.x.x)
* .... * sept. 30 14:13:19 migration speed: 1024.00 MB/s - downtime 65 ms * sept. 30 14:13:19 migration status: completed * sept. 30 14:13:20 ERROR: VM 463 not running * sept. 30 14:13:20 ERROR: command '/usr/bin/ssh -o 'BatchMode=yes' root at x.x.x.x<mailto:root at x.x.x.x> qm resume 463 --skiplock --nocheck' failed: exit code 2 * sept. 30 14:13:24 ERROR: migration finished with problems (duration 00:00:12) * TASK ERROR: migration problems

By chance i tested migrating another VM, which had memory hotplug disabled, and it worked ! So i tried on VM 463, after disabling memory hotplug, and live migration works fine !

* sept. 30 14:14:27 starting migration of VM 463 to node 'proxmoxt20' (x.x.x.x) * .... * sept. 30 14:14:35 migration speed: 1024.00 MB/s - downtime 34 ms * sept. 30 14:14:35 migration status: completed * sept. 30 14:14:39 migration finished successfully (duration 00:00:12) * TASK OK

So it seems that any VM which has memory hotplug enabled won't resume after successfull live migration.. Anyone have the same issue ?

Here are the VM parameters :

acpi: 1 bootdisk: virtio0 cores: 12 hotplug: disk,network,usb,cpu keyboard: fr kvm: 1 memory: 2048 name: mazoutvin net0: virtio=54:52:00:0A:91:60,bridge=vmbr1,tag=36 net1: virtio=54:52:00:0A:91:61,bridge=vmbr2,tag=3 net2: virtio=54:52:00:0A:91:62,bridge=vmbr2,tag=6 numa: 1 onboot: 1 ostype: l26 smbios1: uuid=96d6ad50-6e28-4ece-b936-0b6e87e90c5f sockets: 1 unused0: isilon:463/vm-463-disk-1.vmdk vcpus: 1 virtio0: san_storage:vm-463-disk-1,size=40G

And pveversion:
