hi there, I am currently playing around with the Xen support in FC6. Installation of Xen and FC6 Domain0, setting up a FC6 guest with virt-manager all went well, however I did not succeed in running a second RHEL4(clone) guest I prepped with Qemu. It took quite some time to figure things out, firstly the host is x86_64 and the guest is/was a 32 bit X/OS (Dutch RHEL clone) desktop , but if I understand things correctly there shouldn't be any problems when running a 64 bit kernel with 32 bit userland. Then I had to learn that a initrd for domain0 is not the same as one for a domainU :) After that the guest booted with the FC6 Xen kernel when I disabled SELinux , however udev fails to start which makes the bootup stop on filesystem check time because I used the default LVM setup and the LVM devices are not created, so the rootfs cannot be found. The repair shell however showed the rootfs is mounted on /dev/mapper/VolGroup00-LogVol00 ro and a remount rw does work even though /dev/mapper/VolGroup00-LogVol00 does not seem to exist :? So I decided I needed a Xen enabled RHEL4 x86_64 kernel and got it from http://people.redhat.com/~jbaron/rhel4/RPMS.kernel/. I could also convert the image to a non LVM one (the Centos4.4 guest from jailtime.org does bootup properly even though it has the same udev problem, because of this), but I rather have a fully functional X/OS. Ofcourse there were problems. I could not install the x86_64 kernel inside the X/OS guest booted with Qemu so I tried manually putting things in place. Running '/sbin/new-kernel-pkg --package kernel-xenU --mkinitrd --depmod --install 2.6.9-42.36.ELxenU' produced some errors related to strip and 64bit kernel modules, but the initrd got created. I'm sure I can work around this if needed, however Xen crashes on the RHEL4 Xen kernel right away: # xm create -c VirtualXOS4_test Using config file "VirtualXOS4_test".

If so does anybody know if an updated version exists and were to get it? And then there is pygrub, with the FC6 guest created by virt-manager this works like a charm, however with the X/OS guest it just won't work: # xm create -c VirtualXOS4 Using config file "VirtualXOS4".
