Fix for Unable to open a connection to the libvirt management daemon
When you try to connect to a remote virtual machine host server and get the Virtual Machine Manager Connection Failure window shown below, the problem should be one of only two things. Either libvirtd really isn’t running and you need to start it, or you don’t have openssh-askpass installed.
In this case, openssh-askpass was not installed on my local workstation.
If you have openssh-askpass installed and /usr/libexec/openssh/ssh-askpass exists on your system, then check to make sure libvirtd is actually running on the host machine.
