Re: [ovirt-users] libvirt: XML-RPC error : authentication failed: Failed to start SASL

Hello, Today I updated my ovirt engine v3.5 and all my hosts on one datacenter (centos 7.4 ones).

and suddenly my vdsm and vdsm-network services stopped working. btw: My other DC is centos 6 based (managed from the same ovirt engine), everything works just fine there. vdsm fails dependent on vdsm-network service, with lots of RPC error. I tried to configure vdsm-tool configure --force, deleted everything (vdsm-libvirt), reinstalled. Could not make it work. My logs are filled with the follogin Sep 18 23:06:01 node6 python[5340]: GSSAPI Error: Unspecified GSS failure.

Minor code may provide more information (No Kerberos credentials available (default cache: KEYRING:persistent:0))) ================= I do not want to lose all my virtual servers, is there any way to recover them? Currenty everything is down. I am ok to install a new ovirt engine if somehow I can restore my virtual servers. I can also split centos 6 and centos 7 ovirt engine's. _______________________________________________ Users mailing list Users(a)ovirt.org http://lists.ovirt.org/mailman/listinfo/users
