What do you get on this host if you do 'virsh uri'?  Is it qemu:///session?

Yes.

[vmc@c3rh2 yih]$ virsh uri

qemu:///session

Again, on this machine, what do:

virsh uri
sudo virsh uri

[vmc@c3rh1 yih]$ virsh uri

qemu:///session

[vmc@c3rh1 yih]$ sudo virsh uri

qemu:///system

 

display?  It looks like migration went from a session to a system
libvirtd.  To be honest, I have no idea if session migration is even
supposed to work.  So it's possible you have exposed a bug.

Since you are using RHEL libvirt, would you mind opening a support
ticket with Red Hat?
