you did exactly, what I was looking for for a couple of month now - a FreeBSD kernel as domU for XEN. Great work. Unfortunately I do have problems to set it up. When I use your xen config file and do a xm create, I get either the error, that the memory, I specified is to less for this image (which needs 0xc0c MB - weird size) or - if I set the memory to something higher that this value, xen tells me, that dom0 is running ot of memory... Unfortunately I have only 1GB of RAM in this testing machine...

To start with, the FreeBSD XenU kernel does not have an adequate __xen_guest section for Xen 3.0.3. I attempted to add the missing VIRT_BASE in that section by using objcopy, and that let me boot the VM booting further, but instead of complaining about memory, it just crashes.
Your choices are to either downgrade Xen to 3.0.2 or actually fix the bug(s) and recompile the FreeBSD kernel.
actually I thought I was using 3.0.2. But I have to double-check this, as I might have updated the system at one point... Or are there already any bugfixes available?
Hello there. I am actually using Xen 3.0.2, with Gentoo Linux as dom0 (and Xen compiled with Gentoo's Portage), and I'm not able to run Yuan's freebsd-XENU_INSTALL kernel. I keep getting "Error: (22, 'Invalid argument')", and I tried with both a PAE-enabled and a non-PAE Xen 3.0.2 hypervisor.
Any idea?
Yuan, I don't know the details of the SOC, but are you still working on FreeBSD + Xen ? Anyway, thank you very much for what you've done.

Interesting. A little shelll script I put together to try and get Xen working with Yuan Jue's FreeBSD kernels worked on Kip Macy's kernel, and I can boot it now on Xen 3.0.3. I didn't even try to think about trying the older stuff.
For the interested, here's the small script I used that fixes the __xen_guest section to add the VIRT_BASE that Xen 3.0.3 requires: ---- #!/bin/sh
It's a bit of a pity that all interest in Xen on the FreeBSD mailing lists seems to have died, but many thanks to both Yuan Jue and Kip Macy for the work they've done.
re Kip's kernel, it _boots_, but as I experienced when trying it some months ago, it 'fall asleep' after some work. It's strange, the system more or less seems ok (can login, run top, etc...) but for other things it just stays there forever (eg., I can't make install stuff from ports). But I guess that's because it was an old kernel.
I'm using gentoo linux for Dom0, so I can get Xen from portage and I don't have too much to fiddle around. Right now there is Xen 3.0.2 in portage, and I'd like to run a freebsd DomU on top of that. Not 'production stuff', but at least something working more or less for an home system. Yuan's kernel should do the job, if I find a way to make it load and boot in Xen.
