Xen domU for OpenBSD/amd64 demo

[Mathieu Ropert <mro@adviseo.fr>]

Hi,

you can now download a beta version of the OpenBSD/amd64 port for Xen at 
http://cancel.adviseo.net/Open-BSD

General notes:
- It's a beta, don't expect it to be fully stable. It stills crashes for 
time to time. Feel free to report backtraces and conditions. (I'm 
thinking of hosting a debug kernel image)
- The network driver is included, but still buggy. Most notable bug is 
that network demons don't work, no sshd or ftpd for now :(
- Arithmetic coprocessor support is still missing, so some programs may 
crash/hang
- It's an UP kernel. SMP is currently unsupported..

Kernel image (domU): http://cancel.adviseo.net/Open-BSD/bsd
3.9 default install image: http://cancel.adviseo.net/Open-BSD/disk (root 
password: "adviseo")
Xen-unstable hypervisor image with required patches for OpenBSD: 
http://cancel.adviseo.net/Open-BSD/xen.gz

If you want to make your own image, you'll need to add the following:
- Xen block device node (/dev/xbd*): block dev, major 20
- Xen block device node (/dev/rxbd*): char dev, major 85
- Xen virtual console device (/dev/xencons0): char dev, major 84, minor 0
- Set the root fs entry in /etc/fstab according to your image (most 
likely /dev/xbd0a)
- Add '/dev/xencons0     0600    /dev/console' to /etc/ftab
- Add 'xencons0 "/usr/libexec/getty Pc"   vt220   on  secure' to /etc/ttys

Sources are available too:
Patches for OpenBSD 3.9 release kernel sources: 
http://cancel.adviseo.net/Open-BSD/amd64-xen.patch.gz (use the XENU 
config file in arch/amd64/conf)
Full OpenBSD 3.9 release kernel sources with Xen pacthes: 
http://cancel.adviseo.net/Open-BSD/sys-amd64-xen.tar.gz
Patches for Xen-unstable sources: 
http://cancel.adviseo.net/Open-BSD/xen-patches.tar.gz (make sure it's 
compiled with -DNDEBUG, else BSD won't work)

Have fun!

Mathieu
