Hi.
I use suse linux 11 SP2 + Xen4.1 + HA to create a para-virtualisation VM. VM OS is suse linux SP2. the kenel is vmlinuz-3.0.13-0.27-xen. then i change this VM from para-virtualisation VM to full-virtualization VM. I do below steps.

1) install a new kernel with the suse linux SP2 CD by YST. new kernel is vmlinuz-3.0.13-0.27-default. /boot/grub/menu.lst is update accordingly.
2)chage the /etc/fstab file. update all fields with xvda to hda. same thing for the xvdb ...
3)in Dom0. change the VM startup config files. from
builder="linux"
bootloader="/usr/bin/pygrub"
bootargs=""
extra=""

to
builder="hvm"
device_model="/usr/lib/xen/bin/qemu-dm"
kernel="/usr/lib/xen/boot/hvmloader"

also change all xvdN to hdN.

then startup the vm using xm create <vmconfigfile>.

VM startup successfully. I check the kernel is changed to vmlinuz-3.0.13-0.27-default.

is this method correct? did i missed something?
is there any potential issues to running the legacy software already installed?

Thanks.
