Hi,
I have two nodes and for the last two days I’m getting host errors. Host is actually up but here’re the errors from oned.log
Sat Jul 23 15:14:45 2016 [Z0][ONE][E]: Error monitoring Host host-node01 (0): error: failed to connect to the hypervisor
error: error from service: CheckAuthorization: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.

And of course VMs get into UNKNOWN state.
When I restart libvirtd on the host, everything get back OK. How can I check what is the cause?
And another thng that host hook is active and in sched log, it says there’re VMs to be rescheduled but unable to do:

-------------------------
How can I cancel those pending reschedule. I dont want to cancel the host hook at all.
Thanks, regards,
