[one-users] Cannot live-migrate a VM.

Hi,

I've seen another error like this one in the list for OpenNebula 3.2. So it
is clear that is not related to the bug solved in 3.4.1.

The problem is this record:

 1 tmkvmserv05     none    07/09 16:36:12   15d 17h59m58s    0d 00h00m00s

There is no migration reason (none) so OpenNebula thinks that the VM is
still migrating. Did the migration fail? Could you send us the vm.log file
for this VM (97) and oned.log?

Cheers

Ruben
