[SOLVED] Live migration VM problem in GUI

I'm trying to live migrate this VM to another node from GUI:



At the command prompt, this task is performed successfully:

But if this VM placed in HA then this task started in command line is completed (in GUI) with the same error.

Best regards,

1. you have a vm with local disks
2. the -with-local-disks option is only enabled at the cli level (at the moment)
3. using ha for a vm with local disks does not make sense (if a host is down, you cannot restart it elsewhere, because the disks are missing), so in ha migrate this option is also not enabled

Hi All!
Just created 3-node cluster.

HA and local disks doesn't make sense. how is PVE supposed to recover this VM if the node where it is currently running fails/is fenced?

Ok.
