mount -o loop CentOS-6.0-x86_64-netinstall.iso /mnt/Centos6 cp -a /mnt/Centos6/isolinux/{vmlinuz,initrd.img} /stor/

Is that a pv or pv-ops capable kernel? Have you considered installing as an hvm guest? Regards, Jim

Using this config file

cat /stor/centos6.cfg name = 'centos6' builder = 'linux' kernel = '/stor/vmlinuz' ramdisk = '/stor/initrd.img' maxmem = 1024 memory = 1024 disk = [ 'file:/stor/CentOS-6.0-x86_64-netinstall.iso,hdc:cdrom,r', 'phy:/dev/VG0/centos6,xvda,w'] vif = [ '' ] vfb = [ 'type=vnc, vncdisplay=1, vnclisten=127.0.0.1' ] extra = 'textmode=1 xencons=xvc0' on_crash = 'destroy' on_reboot = 'restart' on_shutdown = 'destroy' localtime = 0

Then 'xmcreate -c /stor/centos6.cfg' crashes at "kernel BUG at fs/sysfs/group.c:65!;Kernel panic - not syncing: Fatal exception". The console output is below.

I'm stumped for now. I searched online for Centos6, Opensuse, Xen, etc. I haven't found a working cfg yet.

I'm having a hard time finding Opensuse virtualization "DocsForDummies". I'd consider anything that works right now. If you can help me tweak my config I'll try that. I'd read in some older threads that you lose performance using a fully- versus para-virtualized Guest. Is that still an issue these days?

but I've read that the domUloader.py is an Opensuse-specific bootloader?

Yes, and not really needed anymore. IIRC, it was originally written as a host bootloader for NetWare, which pygrub now supports too.

Oh. So even if booting an Opensuse Guest these days, we should change

builder = 'linux' bootloader = '/usr/lib/xen/boot/domUloader.py' bootargs = '--entry=xvda1:vmlinuz-xen,/boot/initrd-xen'

to,

builder = 'linux' bootloader = '/usr/bin/pygrub' bootargs = '--entry=xvda1:vmlinuz-xen,/boot/initrd-xen'

No bootargs are necessary. The default kernel in domU's /boot/grub/menu.lst will be selected (which could be overridden with bootargs). bootargs='' should suffice.

Config similar to name="blabla" memory=1024 vcpus=4 ... builder="hvm" device_model="/usr/lib/xen/bin/qemu-dm" kernel="/usr/lib/xen/boot/hvmloader" boot="d" disk=[ 'file:/var/lib/xen/images/sles11sp1 gmc-hvm/disk0,hda,w', 'file:/path/to/centos6.iso,hdc:cdrom,r', ] ... /etc/xen/examples/ contains quite a few examples for both pv and hvm.

So, HVM works so far.

"So far" seems to only go as far as the Centos6 graphical installer displaying: Loading vmlinuz ....................................................... Loading initrd.img ................. and it gets no further. Scientific Linux 6.1, otoh, gets past that point and it currently "Checking media". I've no clue if these problems are Opensuse's, Xen's, or the Guest OS'. Any thoughts?
