Hi All,
(please feel free to refer me to the official Xen list if need be)
I am still using the same dom0 as outlined in :
https://www.redhat.com/archives/fedora-xen/2008-March/msg00006.html
I can successfully boot a domU using /dev/hda1 as rootfs but when I boot using a scsi device it is unable to find its rootfs. I created an initrd, preloading the sd_mod, in the hopes that that will fix it. The initrd was created like so:
# mkinitrd -v --preload=sd_mod --preload=xenblk --with=xennet --with=xenblktap --with=xenbus_be /tmp/test `uname -r` # cp /tmp/test /boot/initrd-2.6.21.7-2.fc8xen.img
And the config of the guest is:
kernel = "/boot/vmlinuz-2.6.21.7-2.fc8xen" ramdisk = "/boot/initrd-2.6.21.7-2.fc8xen.img" extra = "ro enforcing=0" root = "/dev/sda1" memory = 256 name = "centos.5-1.64" vif = [ '' ] disk = ['phy:VolGroup00/LogVol00,sda1,w']
But is fails to boot, here are some possibly relevant messages with the complete output at the end of this email :

Loading scsi_mod.ko module SCSI subsystem initialized Loading sd_mod.ko module Loading xenblk.ko module register_blkdev: cannot get major 8 for sd vbd vbd-2049: 19 xlvbd_add at /local/domain/0/backend/vbd/22/2049 register_blkdev: cannot get major 8 for sd vbd vbd-2049: 19 xlvbd_add at /local/domain/0/backend/vbd/22/2049 XENBUS: Timeout connecting to device: device/vbd/2049 (state 6) [ lines removed ] unmounting old /dev unmounting old /proc unmounting old /sys switchroot: mount failed: No such file or directory Booting has failed. Kernel panic - not syncing: Attempted to kill init!
I am glad I can successfully boot a guest but I would still like to get to the bottom of this problem.
Thanks!
Fred.
