[Pkg-libvirt-maintainers] Bug#682493: libvirt-bin: virsh takes a long time to connect to xend

Package: libvirt-bin
Version: 0.8.3-5+squeeze2
Severity: normal


On any host running Xen 4.0 I'm getting a high delay in virsh operations:
| root at wildebeest:~# time virsh list
|  Id Name                 State
| ----------------------------------
|   0 Domain-0             running
| real	0m6.333s
| user	0m0.004s
| sys	0m0.008s

On any system with QEMU/KVM the response is much much faster:
| real	0m0.009s
| user	0m0.000s
| sys	0m0.008s
