The Xen Live CD teachs how to do that easily!
- Example of how to convert Linux virtual machines from HVM to PVM. With the new paravirt_ops, this can be done smoothly.

Hello,
really new to CentOS, I need a VM running CentOS. Right now, it is
running in full virtualized mode, but I want to switch to
paravitualization.
What I did:
yum install kernel-xen
Changed menu.lst to boot xen kernel per default
My configuration in dom0 (OpenSuse):
name="centos5"
uuid="6e50b775-3b29-f38a-610d-9368dda96dd1"
memory=1536
maxmem=1536
vcpus=1

localtime=0
keymap="de"
builder="linux"
bootloader="/usr/lib/xen/boot/domUloader.py"
bootargs="--entry=xvda1:/boot/vmlinuz-2.6.18-164.15.1.el5xen,/boot/initrd-2.6.18-164.15.1.el5xen.img"
extra=" "
disk=[ 'phy:/dev/xen/centos5,hda,w', ]
vif=[ 'bridge=br1,model=rtl8139', ]
vfb=['type=vnc,vncunused=1']
If I want to boot the VM, the lat 5 lines from the console output are
these:
SCSI subsystem initialized
device-mapper: uevent: version 1.0.3
device-mapper: ioctl: 4.11.5-ioctl (2007-12-12) initialised: dm-devel@xxxxxxxxxx
device-mapper: dm-raid45: initialized v0.2594l
Kernel panic - not syncing: Attempted to kill init!
Any hint is appreciated,
Rainer
