Hi,
how can I access libvirt/virsh on oVirt node? What are the credentials
for accessing libvirt/virsh on the command line of a oVirt node?
virsh # list
Please enter your authentication name:
Please enter your password:
error: Failed to reconnect to the hypervisor
error: no valid connection
error: authentication failed: Failed to step SASL negotiation: -1 (SASL(-1): generic
failure: All-whitespace username.)
It would make debugging things much easier...
Thanks

You can always set your own credentials for libvirt (without touching those
of vdsm/oVirt):
saslpasswd2 -a libvirt foo
where foo is the new username.
virsh # list

You can execute virsh using the -r or --readonly options. You can't
change anything that way, obviously, but you should be able to read all
the information from libvirt. All changes need to be initiated through
ovirt-engine and then through vdsm.

Hi Tobias,
Storage domain live upgrade is now supported. This means you can upgrade from an old data
center format to V3 while VMs are still running in your system.
A little more info is available on:
http://www.ovirt.org/Features/StorageDomainLiveUpgrade .
Best Regards,
Vered

Using --readonly works like a charm and does not hurt oVirt.
This is the way to go! Thank you!

You can always set your own credentials for libvirt (without touching those
of vdsm/oVirt):
saslpasswd2 -a libvirt foo
where foo is the new username.
But please note that accessing libvirt without the --readonly flag may
lead to tears. By doing so you revoke the warrenty you never had.

virsh # list
Try open it for read-only:

Please enter your authentication name:
