Hello all,
I'm working on trying to build hvm xen guests based on our kickstart
servers, but it seems to be failing. I'm using CentOS 5, running kernel
2.6.18-8.1.15.el5.centos.plusxen and the xen 3.0.3-25.0.4.el5 rpm. I built
libvirt 0.3.3 and python-virtinst 0.300.1 in order to test the pxeboot
setup, but virt-install errors out and xm list shows the guest still
running, but state is just '------' and Time is '0.0'. Shutting it down and
creating it again causes it to shutdown immediately.
I have a feeling the issue is that my xen install isn't new enough to
support it. The qemu-dm log file says "qemu: invalid boot device in 'n'",
which makes me think that network booting isn't actually set up in my
installed version of qemu-dm. I just want to check to make sure it's not
something else before I go and backport xen 3.1 into the kernel rpm in
order to get the right qemu-dm binary.
I'm including the virt-install output as well as the xend.log and
relevant /var/log/messages entries. The xend-debug.log and xen-hotplug
didn't give any errors.
If anyone sees anything I've done wrong, would like more information, or
can give me general input on getting fully virtualized xen guests to
kickstart from pxeboot (or something similar), just let me know. I'd
really appreciate it.
Thanks,
Brendan Wood

Here is the command line I used and the resulting errors:
