I’m curious to know if anyone has successfully booted Haiku in Xen using full virtualization (HVM). I see an older conversation talking about porting Haiku to use paravirtualization; that would be cool, but it’s not what I’m concerned with right now.
I attempted to use full virtualization in Xen using the QEMU image, and was presented with some hopeful information right before a kernel panic. For anyone interested here’s the output:
xen:/etc/xen# xm create -c /etc/xen/haiku.hvm
Using config file "/etc/xen/haiku.hvm".

You'll want to file a bug report at http://haiku-os.org/trac if you want one of the devs to look into it.
Also, it would be helpful if you could run a stack crawl (sc or bt - i can’t remember) from the kdl prompt when posting the output
Will do. I’m more curious to know if anyone has had any success yet - I haven’t seen anyone imply that Haiku should work with Xen HVM yet, but it would be cool. I’m running Win2k3 on Xen/Linux and I imagine Haiku could be tweaked (maybe without code changes) to work as well .
That sounds suspiciously like http://haiku-os.org/trac/ticket/748 I previously had problems with the kqemu module, and while I know it doesn’t do the same thing the problem could be related.[/url]
I booted a Xen DomU off of a BeOS 5 disk image that I had previously set up according to this procedure. It Just Worked!
This is with the 3.4.0 Xen kernel and the Git xen-tip/next Linux kernel - the bleeding edge development. I needed that to support my AMCC 3ware 9690SA RAID, but the Linux source that comes with the 3.4.0 release should work for most people.
Here is my DomU config. I’m copying the install from the image into a physical partition, for faster performance. You will want to adjust specs for your own setup:
import os, re
arch = os.uname()[4]
if re.search('64', arch):
arch_libdir = 'lib64'
else:
arch_libdir = 'lib'
