Updates comes only from stable.

Updates from good to broken:
linux-image-2.6.32-5-xen-amd64 from 2.6.32-31 to 2.6.32-38
libvirt-bin from 0.8.3-5+squeeze0 to 0.8.3-5+squeeze2

Then libvirt-bin from 0.8.3-5+squeeze2 to 0.9.2-7~bpo60+1, still broken.

I invoke "LIBVIRT_DEBUG=1 virsh list" from console via SSH.

> * Anything in the kernel log?

No, nothing suspicious while connecting or at boot time.

> * How did you adjust the xend configuration?

Here is my xend-config.sxp:

(xend-unix-server yes)
(vif-script vif-bridge)
(dom0-min-mem 196)
(enable-dom0-ballooning yes)
(total_available_memory 0)
(dom0-cpus 0)
(vncpasswd '')

As far as I remember, this is default except "(xend-unix-server yes)". It 
works fine with 2.6.32-31.

* Did you make sure libvirtd got restarted?

Yes, and server got rebooted few times.
