yes, it looks like a different use case

moVirt has been developed for quite some time and works pretty well, this
is why I recommended it. But anyway, you have a different use case.

What I think the issue is, is that oVirt can have different CAs set for
console communication and for API. And I think you are trying to configure
aSPICE to use the one for API.

What moVirt does to make sure it is using the correct CA to put into the
aSPICE is that it downloads the .vv file of the VM (e.g. you can just
connect to console using webadmin and save the .vv file somewhere), parse
it and use the CA= part from it as a certificate. This one is guaranteed to
be the correct one.

For more details about what else it takes from the .vv file you can check
here:
the parsing:

enjoy :)
