[Pkg-libvirt-maintainers] Bug#564902: virt-manager should cleanup before leaving

[Harald Dunkel]

Package: virt-manager
Version: 0.8.2-1
Severity: important

To connect to remote kvm hosts via virt-manager I use

	qemu+ssh://hdunkel@hostname/system

Problem: virt-manager does not terminate the remote helper
applications on exit. After 20 virt-manager sessions I see
20 processes writing to the Unix socket:

% ps -ef | grep vir | grep soc[k]

hdunkel  30700     1  0  2009 ?        00:00:00 nc -U /var/run/libvirt/libvirt-sock
hdunkel  31233     1  0  2009 ?        00:01:13 nc -U /var/run/libvirt/libvirt-sock

This is fatal, because 20 is the max. On further attempts to
run virt-manager or virsh or any other libvirt tool I get

	error: cannot recv data: Connection reset by peer
	error: failed to connect to the hypervisor

Virsh ("virsh -c qemu+ssh://hdunkel@hostname/system") terminates
the remote helper as expected, so I would assume this is something
specific for virt-manager.

Nc is from netcat-openbsd version 1.89-3.
