By default virt-manager creates VMs using SPICE remote display protocol.
Using SPICE requires openin of many TCP connections (as many as 10 in
some cases). So if you've not setup SSH agent with keys, you are going
to see a large number of password prompts due to all the connections
that must be opened.
We strongly recommend against relying on password prompting - SSH agent
and keys are what you should aim for otherwise usability is horrible with
all the password prompting.
