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 <[email protected]> wrote: > > > > From: [email protected] > > To: [email protected] > > Date: Tue, 20 Jul 2010 13:31:48 +0200 > > CC: [email protected] > > 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.
