Hi Mike,

Do you have both hosts individually set up in the GUI, so that you're 
able to open a connection to either one of them as needed?

For example, with the testing setup here at the moment, virt-manager is 
configured for two hosts.  host1, and host2.  Nothing special configured 
with them, they're just standard connection setups.  Either host be 
connected to in order to start guests, stop them, delete them, etc.

 From the main virt-manager window, if I right click on a running guest 
the context menu gives me a "Migrate..." option.  Clicking that opens a 
dialog to choose the destination host... any other host that 
virt-manager knows about.  (this is probably the bit you need to know)

For a guest on host1, it gives me the "host2" option.  For a guest on 
host2, it gives me the "host1" option.  (hope that makes sense)

To add more hosts as potential migration targets (in virt-manager), they 
need to be set up individually with virt-manager first, so it knows they 
exist.

Does that help?

Regards and best wishes,
