Anyone tested live migration yet? I have problems with migration reliability. Especially ubuntu 11.10 beta2 (and xubuntu 11.10 beta2) seems to be a bit tricky. Migration succeeds often, sometimes VM is frozen after migration but quite often VM just shuts down on the target host. Web UI says "TASK OK" in all cases. Setting lover migration speed seems to help a bit and so does setting migration downtime to 0 (default is 1 second). There seems to be no difference between virtio vs ide or virtio vs e1000.
I have two node cluster and two types of shared storage. Drbd and iSCSI target both as backend for logical volumes. Same problem with both. Host machines are quite different though. Other is AMD Athlon X4 and the other one is Dual Core 2 E8500. I realize best practice is to use indentical machines but on the other hand migration is supposed to work across CPU vendors (and it does but not reliably).
I'm not sure that this is purely proxmox problem because I noticed the same thing when I was developing my own management script.
So, could someone test (preferably ubuntu 11.10 beta2) and report how live migration works.
Thanks
