You installed askpass, but virt-manager can't find it, it's trying to
use /usr/libexec/openssh/ssh-askpass which is probably not there.
Check where it got installed and why it can't run it.

Anyway, the easiest thing for you would be to deploy ssh keys for
password-less login (or just requiring unlocked keyring)
