Hi,

The certificates on our oVirt stack recently expired, while all the VMs are 
still up, I can't put the cluster into global maintenance via ovirt-engine, or 
do anything via ovirt-engine for that matter. Just get event logs about cert 
validity.

VDSM ovirt-1.xxxxx.com command Get Host Capabilities failed: PKIX path 
validation failed: java.security.cert.CertPathValidatorException: validity 
check failed
VDSM ovirt-2.xxxxx.com command Get Host Capabilities failed: PKIX path 
validation failed: java.security.cert.CertPathValidatorException: validity 
check failed
VDSM ovirt-3.xxxxx.com command Get Host Capabilities failed: PKIX path 
validation failed: java.security.cert.CertPathValidatorException: validity 
check failed

Under Compute -> Hosts, all are status Unassigned. Default data center is 
status Non Responsive.

I have tried a couple of solutions to regenerate the certificates without much 
luck and have copied the originals back in place.

I have seen things saying running engine-setup will generate new certs, however 
engine doesn't think the cluster is in global maintenance so won't run that, I 
believe I can get around the check with `engine-setup 
--otopi-environment=OVESETUP_CONFIG/continueSetupOnHEVM=bool:True` but is that 
the right thing to do? Will it deploy the certs on to the hosts as well so 
things communicate properly? Looks like one is supposed to put a node into 
maintenance and reenroll it after doing the engine-setup, but will it even be 
able to put the nodes into maintenance given I can't do anything with them now?

Appreciate any ideas.
