Hi guys,

i've just created/ran my first virtual machine on/from CentOS 5.4 Dom0.
I installed it onto drbd device, using an Debian iso image from http://stacklet.com. I've also extracted the kernel and initrd out to my Dom0 and configured it like this:
kernel = "/bootvirts/vmlinuz-2.6.26-2-xen-amd64"
ramdisk = "/bootvirts/initrd.img-2.6.26-2-xen-amd64"
disk = ['drbd:r0,sda1,w']
root = "/dev/sda1 ro"

What i'm wondering now is, how the kernel updating will work or how it's supposed to work? User of this virtual machine will be able to update the kernel on drbd device (in his virtual machine) but not in /bootvirts/ on Dom0, as it's not accessible from within virtual machine. Or am I mistaken?

Thank you for your time,
Regards,
M.
