TLS client verification used to be accidentally disabled in libvirt.
This was fixed in libvirt-6.10.0-1[1].
Which means, once you're using libvirt-6.10.0-1 or higher, a client
certificate is mandatory during live migration with TLS.
In this case, the server certificate generated by TripleO is valid
for client _and_ server:
Key Purpose (not critical):
TLS WWW Server.
TLS WWW Client.
So most deployments can re-use the same certificate for client and
server. Why? Because if both migration ends points are located
on the same infrastructure, it is reasonable to use the same
certificate for both client and server roles.
Introducing QemuDefaultTLSVerify parameter
This parameter will allow operators to enable or disable TLS client
certificate verification. Enabling this option will reject any client
who does not have a certificate signed by the CA in
/etc/pki/qemu/ca-cert.pem.
The default is true and matches libvirt's. We will want to disable this
by default in train.
