Hi,
I needed help with changing the kernel on a DomU using virt-manager.
I had an initial install of a Fedora core 7 domU. Now I have added
some patches of my own to the standard domU kernel and I want to use
it as the the new DomU. How can I do it using virt-manager?
Have you already compiled your locally patched kernel and tested it?
If you have done that bit, which is the hard part in my opinion, then
you can create a new distro using this kernel and initrd pretty easily
in cobbler. check out the man page for cobbler (man cobbler) and read
the section on creating a new distro. if you are having specific
problems let us know!

I think he's asking about how to change the kernel of an existing
virtual machine without reinstalling it.
After installation is complete (i.e. on subsequent boots), Xen gets the
kernel/initrd information from the bootloader, so all you should really
need to do is upgrade the kernel from inside the virtual machine as if
it were any other kernel -- and restart the machine. The next time it
comes up, Xen should find the new kernel.
