[Xen-devel] Unable to start a guest in Xen 4.0.1-rc5-pre

[Jonathan White <jonxwhite@xxxxxxxxx>]

Hello again,

Quick recap: I have a working Xen 4.0.1-rc5-pre booting smoothly on x86_64 on a FC12 Linux platfrom. xend starts automatically and xm list shows the Dom0. I disabled selinux by adding selinux=0 in the kernel line in grub.conf for the Xen kernel.

Now I would like to run a simple guest domain (Linux or Windows). Ideally I would like to install a fresh HVM domain (preferably Windows XP) 
I have been trying to start a simple guest but have been unsuccessful so far. The examples in the user.pdf document is Xen 3.3 based and assumes the presence of a /boot/vmlinuz-2.6-domU kernel image which does not get built in Xen 4.0.

I unsucessfully tried the following:
1. I created a 8GB empty disk image using dd (see below) and tried to install a WinXP from a CD, using xm create. The guest domain started but stopped after a few seconds. I took xmexample.hvm in /etc/xen as baseline and edited it. 
dd if=/dev/zero of=winxp.img bs=1M count=0 seek=8192
2. Same as above, but with Linux FC11 x86_64 CD.
3. I used xmexample1 and tried to launch the vmlinuz-2.6.31.13 that gets built as part of Xen make in /boot. But that too failed to start.

My questions is - Is there a step by step instructions somewhere on how to run a simple guest (both paravirtualized - for linux and hvm - for Windows) for Xen 4.0? Preferebly I would like to install fresh guest OS from an install CD. 
I know I haven't provided any logs or specific errors, but I can do so if you can share which logs would be interesting.

Thanks a lot,
Jon
