I assume you meant installing a paravirtualised F7 as domU, not dom0? (if it were dom0 you could just use the F7 installer and specify that you wanted virtualisation). Converting it in this way should be fairly straightforward. Use yum in your domU and get it to install the F7 Xen-enabled guest kernel (don't install the Xen package itself, you don't want the hypervisor or tools). This may configure a guest entry in grub automatically, or you may have to add one for your guest kernel and initrd manually - I've not used F7 much, so I'm not sure. Then you need to change the configuration for the domain to be paravirtualised... I assume you're using virt-manager? I don't know if the version in F7 stores config files in /etc/xen/? In which case you could just copy / alter those config files to conform to a PV guest. If not, I understand you can use "virsh" to dump the config file into XML form, then modify it, then reload that file to change the config used for the domain. To convert it to PV you'll basically want to remove all the HVM-isms (e.g. stuff like the ioemu devices, the hvmloader, the builder, etc may need to be changed) and add in the relevant PV-isms (e.g. different syntax for describing virtual framebuffer, "linux" builder, pygrub bootloader, device names changed to xvd*). Then if you boot the domain with xm create -c you ought to see the pygrub screen appear; select the Xen-enabled grub entry that you installed. It should boot (fingers crossed). If you keep a copy of the original HVM config you should be able to switch between the two fairly easily for debugging purposes. If you installed the guest to use partitions, not LVM, then it's trivial to mount the guest's filesystem from dom0 to make tweaks. Cheers, Mark -- Dave: Just a question.
