Hi guys.
I have a problem getting migration traffic encrypted for some scenarios. I need to
migrate domain with non shared disks and can't use tunelled migration because of
RHEL7 qemu.
Without tunnel i get both vm state and disk state traffic unencrypted between
peer's qemus. AFAIK there is a work in progress in qemu to bring TLS encryption
to all channels and eventually I get desired functionality but what are my options
now?
I thinking of forwarding ports from destination to source and use localhost in
hypervisor uri. The only problem is that port for disk migration is auto selected.
Can we add a patch to pass this port as a migration parameter?
We already have a migration URI, where you can specify the port:
http://libvirt.org/migration.html#uris
so working around the lack of encryption should be possible.
The listen address can now also be specified if you don't want QEMU to
listen on all interfaces:
