Pkg xen devel - Oct 2006 - Bug#391448: xen-hypervisor-3.0-unstable-1-i386: dom0 crashes when starting the 3rd domU

Package: xen-hypervisor-3.0-unstable-1-i386
Version: 3.0-unstable+hg11561-1
Severity: important

I've installed
xen-linux-system-2.6.17-2-xen-k7 (version 2.6.17-9)
on a server, and planned to run 3 Xen domUs on it. Creating the domUs
was no problem, and running two of them works well. Starting the third
one however will crash the dom0 and forces it to reboot.

The machine is a Athlon64 3800+ with 1GB RAM, each domU is configured
with memory=256. It uses bridged networking, which works fine with 2
running domUs. Starting the third domU without a vif does not make any
difference, nor does starting the third using a file based disk image
insted of a LVM baes one.

Unfortunately I have only ssh access to the machine in question, so I
don't know what exactly is happening at crash-time.

If someone has an idea how to debug the problem, I will gladly provide
any information to help fixing it.

Known bug in the kernel, use 2.6.18.
