[Fedora-xen] DomainU crashing - Zombie

[Kwan Lowe]

Hello all:
  After doing some recent updates I've noticed that one previously stable domain is
now crashing regularly.  The dom0 is running 2.6.17-1.2187_FC5xen0 and the
corresponding domU kernel on the virtuals.  Dom0 hardware is an Athlon XP 2200
with 1G RAM. This occurs under moderately heavy network. The crashed domain is a
fileserver image with a physical disk and was serving up a Solaris installation
iso when it died.

The DomU will not shutdown with "xm shutdown" or "xm destroy" and I need to kill -9
the "xend start" processes to force it down. This also prevents the Dom0 from
rebooting.

Ahh... And just noticed that I can't "xm shutdown" two running VMs either. They both
go to Zombie state.
