Subject: [PATCH] [virsh] Call virsh commands in the foreground / with a TTY
In some virsh errors (like unable to connect to a hypervisor),
the tool requires to communicate to TTY otherwise it can get stuck
(when called via Popen with a timeout).
Calling it on foreground prevents the stuck / waiting on cmd timeout.
