Hi, You may install a "provisioning" HVM instance where you can mount a disk/filesystem. After you compiled the source you can make installworld/installkernel DESTDIR=mynewsystempath and there you go. Also don't forget a make distribution. :) After this you can easily do an image with dd if you're also using LVM for XEN "disks". The provisioning HVM instance might come handy any you have a problem with a PV instance.
