virt-manager: socket closed unexpectedly

Binary package hint: virt-manager

Hi there,

Currently i'm testing out XEN as an alternative to vmware as our hypervisor, but it seemed that there wasn't any good GUI's around until i stubled into virt-manager, however i'm having a bit trouble getting it to work. Below is the last entries from my client machines virt-manager log.

I have verified that the virtd daemon is running.
landebnxvms007:~# /etc/init.d/libvirt-bin status
Checking status of libvirt management daemon: libvirtd running.

There is a ssh trust relationship established between the 2 hosts and it works.

The xend service is also running well.

Now i'm stuck, and haven't got anymore ideas to what I should check for :-).

On the remote machine, can you get a list of Xen domains using virsh?
Something like "virsh -c xen:/// list --all" should do it.

Hi Soren,

Virsh gives this output:

landebnxvms007:/home/troels# virsh -c xen:/// list --all
libvir: error : could not connect to xen:///
error: failed to connect to the hypervisor

landebnxvms007:/home/troels# dpkg -l | grep libvirt
ii libvirt-bin 0.4.0-1~bpo40+1 the programs for the libvirt library
ii libvirt0 0.4.0-1~bpo40+1 library for interfacing with differeny virtu
ii python-libvirt 0.4.0-1~bpo40+1 libvirt python bindings

Maby this version of virsh is just broken?, there is a newer version in SID and lenny is it possible to use one of them?.

Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue for you. Can you try with the latest Ubuntu release? Thanks in advance.
