Hi,
I would like to restore a domain.
I think, after restoring the domain, the vnc-port
maybe has changed (because e.g. another domain use the old VNC-port
at the meantime).
I guess this could happen yes.
If I do not know the domainname I restored, I have no possibility
to get this vnc-port or connect to the restored domain. Is this correct ?
You would need the name or UUID, yes to then do a lookup
So, would it not be better to change the API to
virDomainPtr virDomainRestore(Conn, from)
In theory, yes. In practice we can't change an existing API,
and that assumes the given hypervisor used at that point will give
the information back. The format for the save are hypervisor specific
(though there is some talks of convergences) but in any case the
UUID and name informations are embedded in the file, whether it's feasible
to extract the informations and add an API is a bit unclear but I guess
that should be feasible generally by just looking at the first blocks of
the data.
