[one-users] Error in VM migration - wrong state to perform action

[Ruben S. Montero]

Hi

Your VM has reached and inconsistent state. Probably because of a bug. The
reason because OpenNebula refuses to migrate your VM is this history record:

   3        kvm-04   none  07/31 12:33:13 00 21:40:10 00 00:00:00

As you see there is a previous host (kvm-04) without any migration reason
so, OPenNebula thinks that the VM is actually migrating. Upon the migration
failure this entry should have been updated.

Could you please send the vm.log for this VM, and your oned.log file? I'll
try to track down this issue.

Thanks for reporting!

Ruben

PS: The only way to overcome this is directly change the DB, and set reason
to any other value for that entry. Also I suggest to upgrade to 3.6
