Hi,

Libvirtd is in listen mode.

/etc/libvirt/libvirtd.conf

listen_tls = 0
listen_tcp = 1
auth_tcp = "sasl"

my trying to setup polkit authentication using
http://wiki.libvirt.org/page/SSHPolicyKitSetup

[root at aopcach ~]# cat
/etc/polkit-1/localauthority/50-local.d/50-org.arindam-libvirt-remote-access.pkla
[Remote libvirt SSH access]
Identity=unix-user:arindam
Action=org.libvirt.unix.manage

but it fails with:

[arindam at aopcach ~]$ virsh -c qemu+ssh:///system
