[Users] Access libvirt/virsh on oVirt node
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 - Frank

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 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.)

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. Mike

Hi, is it possible to do a live upgrade e.g. update from 3.0 to 3.1 without any downtime? Best regards, Tobias
Hi Tobias, Are you talking about ovirt or RHEVM? I know I upgraded with 0 downtime migrating from RHEV 3.0 ~> 3.1 Thank you, Christian Hernandez 1225 Los Angeles Street Glendale, CA 91204 Phone: 877-782-2737 ext. 4566 Fax: 818-265-3152 christianh@4over.com <mailto:christianh@4over.com> www.4over.com <http://www.4over.com> On Thu, Feb 7, 2013 at 6:39 AM, Tobias Honacker <Tobias@honacker.info>wrote:

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 ----- Original Message -----

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

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: $ virsh -r
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...
