So this seems ok.
My dom0 is x86_64.
Does this mean I have to use hvm-pv (XENHVM) -> FreeBSD amd64 install?
Or can I run the i386 pv (XEN) on a 64 bit dom0 too?
Does this also needs a copy of the compiled kernel to the dom0?
Do note that the default 8.0-RELEASE cd does panic (this is part of the
config, when trying to do a normal install to compile the new kernel
(that is why I used VMware to compile the kernel)):
...
builder = "hvm"
kernel = "/usr/lib/xen/boot/hvmloader"
device_model = "/usr/lib64/xen/bin/qemu-dm"
...
Hi,
You can any guests arch that fits into the xm info's xen cap line, so a
32bit pv guest is not a problem for you. We use the following example
config:
kernel = "/usr/lib/xen/boot/hvmloader"
#kernel = "/path/to/pvkernel"
builder='hvm'
memory = 1024
name = "FreeBSD8"
vif = [ '' ]
disk = [ 'phy:/dev/volgroup/freebsd-lv-rootfs,hda,w',
'file:/path/to/8.0-RELEASE-amd64-disc1.iso,hdd:cdrom,r' ]
boot="cda"
vnc=1
vncpasswd='ihavepassword'
#vcpus='2'
The commented parts are should be tried only after a succesful install
and of course the amd64 iso could be an i386 also. Under 3.3.1 Xen it
works one a X2270 test server and a x2250 prod server.
Regards,
Andras
