           Summary: rebooting vm results in multipe startup of same vm
           Product: Xen
           Version: unspecified
          Platform: Other
        OS/Version: Linux
            Status: NEW
          Severity: normal

We rebooted 2 virtual machines at the same time. They nicely rebooted but one
of the 2 machines was booted 2 times.

The reboot-command was executed on both host on the same time. This was the
command executed on the virtual machines:
(sleep 1; /sbin/shutdown -r now) &>/dev/null &

The dom0 and domUs are CentOS4 machines with following xen installed:
[root@XENHOST ~]# rpm -aq | grep xen
glibc-common-2.3.4-2.13.xen.0.c4
glibc-2.3.4-2.13.xen.0.c4
kernel-xen-2.6.18-3.1.0
xen-3.1.0-1

[root@XENHOST ~]# xm list
Name                                      ID   Mem VCPUs      State   Time(s)
Domain-0                                   0   128     2     r-----   9166.2

TMS-3B                                    30   512     1     -b----     82.7
TMS-4B                                    33   512     1     -b----     75.1

In the past years we never saw this problem, but it could be reproduced
multiple times on this specific machine.
