Hi,

It seems, that virt-manager tries to run openssh-askpass on your Windows PC,
this is probably something, that we should fix in virt-manager.

Try to setup password-less ssh connection from KVM2 to KVM1:

    'ssh-copy-id user at KVM1'

this will copy your public key from KVM2 to KVM1 host and than ssh connection
doesn't require password and therefore it won't try to run the 'ssh-askpass'.
