[Pkg-xen-devel] Bug#619253: xen-utils-4.0: xend service can't start because of xenstored segfault

[Maciej Galkiewicz]

Package: xen-utils-4.0
Version: 4.0.1-2
Severity: normal
Tags: squeeze

I have 3 VM running. I have upgraded debian squeeze to 6.0.1 (new kernel
package 2.6.32-31) and restarted my server. VM were still running. After
reboot I could not start xend service (from init.d). I got following
errors:
