Hi Shani,
I actually came across that option and attempted it at one point,
but vdsm has locked me out of using that command it seems.
Eg:
[root@ovirt-node217 ~]# virsh undefine vm-s2
Please enter your authentication name: admin
Please enter your password:
error: failed to connect to the hypervisor
error: authentication failed: authentication failed
No known username/password seems to work.
Is there some magic user to use for this, or some way
to bypass the authentication?
Thanks
David
