[ovirt-users] Re: Destroyed VM blocking hosts/filling logs

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?
