[ovirt-users] It is possible to use vdsClient / virsh to start VMs in the event that engine is down?

[Liam Curtis]

Thank you Jiri!

I had tried this, but your post made me think of googling
/etc/libvirt/passwd.db a bit more and discovered the sasldblistusers2 -f
/etc/libvirt/passwd.db command which showed me 2 users including
root at localbox...when I entered that user it worked. Still cannot start
turned-off vms this way, but its furtehr than I got.

Thanks again.
