If you're booting the XEN kernel, it's going to need to be running in paravirtualized mode. It lacks drivers for non-XEN devices. Also, I have found the XEN kernel running in paravirtualized mode to be nowhere near stable enough for production use. I have used 8.0 with the GENERIC kernel in several domUs (running on Xen 3.4.2 and 4.0) successfully. This config file will work for an 8.0 box: # Name of the domU name = "freebsd-01" # HVM options kernel = "/usr/lib/xen/boot/hvmloader" device_model = "/usr/lib64/xen/bin/qemu-dm" builder = 'hvm' # Virtual hardware configuration vcpus = 1 memory = 512 disk = [ 'phy:/dev/SystemDisks/freebsd-01.root,hda,w' ] vif = [ 'type=ioemu,bridge=eth0' ] # Console and other options serial = 'pty' vfb = [ 'vnc=1,vncdisplay=1' ] On Tue, Jul 20, 2010 at 7:45 AM, G VM <drums_...@hotmail.com> wrote: > From: a...@nirgal.de > To: got.and...@deployis.eu > Date: Tue, 20 Jul 2010 13:31:48 +0200 > CC: firstname.lastname@example.org > Subject: Re: FreeBSD DomU: Upgrade from 7.2 to 8.0 > > Hello, > > Am 20.07.2010 um 12:52 schrieb Gót András: > > > How's your domU config file for xen? > > Up until 7.2 i have used the GENERIC Kernel and never built one of my > own, because there was no need.

I always used hvm with FreeBSD 7.2 >From the moment I upgraded to 7.3 or 8.0, I get a kernel panic. Even the install cd does not boot for 7.3 or 8.0. I did not fixed this yet. I would think that this is happening since there is some virtual stuff included in the kernel by default now and this was not there in 7.2 Maybe you can just disable hvm or something in the kernel config. As IIRC with HVM the OS is not aware that it is virtualised. Please let me know if you find a solution!

There are virtualization extensions on the cpu and those are enabled. (do note that I am using an AMD chip). It just does not run 8.0 and 7.3(nor the 64 bit nor the 32bit cd). 7.2 is running very stable for me. So I would expect that this wont fix this issue.
