Re: [virt-tools-list] why -no-kvm flag?

I tried, but for whatever reason it seems virsh cannot connect - here's what I get:

[dan gennady-dt ~]$ virsh dumpxml zzzzz
error: failed to get domain 'zzzzz'
error: Domain not found: no domain with matching name 'zzzzz'

[dan gennady-dt ~]$ virsh list
 Id Name                 State

[dan gennady-dt ~]$ ps aux | grep qemu

Are these newly created VMs, or existing ones that worked fine before
the update? Can you post the output of 'virsh dumpxml $vmname' for an
affected VM?
