[libvirt-users] Using qemu+ssh on openSUSE 13.1/Tumbleweed

Hi everyone,

I am trying to get libvirt with qemu-kvm to work on my machines
running openSUSE 13.1 / Tumbleweed. My question is in regard to using
qemu+ssh, which would be my preference, as I already have a working
ssh-key authentication with SSH-Agent.

I set the permissions of the manage-socket to 0770, added my user to
the libvirt group and set auth_unix_rw = "none" in
/etc/libvirt/libvirtd.conf.

I am now able to see all my VMs using
	virsh list --all
(I had to set a default_uri in .config/libvirt/libvirt.conf to get any
non-empty output).

Trying from another machine (say target hostname is HOSTX, username
testuser) with virsh -c qemu+ssh://testusers@HOSTX/system always
results in
>> error: failed to connect to the hypervisor error: internal error:
>> received hangup / error event on socket

I see this in /var/log/messages (lines will be wrapped in the mail,
sorry):

I am curious about the 'Received disconnect from 192.168.79.8: 11:
disconnected by user' thing.

How can I fix this? Or how to debug this? How can I get more info from
libvirt? /var/log/kvm is an empty directory, /var/log/libvirt/qemu
just has logs for the different VMs.

I have already tried to get polkit running, although I think it should
not be used due to the auth_unix_rw = "none".

Any help will be appreciated.

obviously a curse of some sort).
