Hi to all.

I''m installed XEN3.1 correctly but I''m some problem to start
it. XEN
start but I received this message:

VFS: Cannot open root device "hda5" or unknown-block(0,0)
Please append a correct "root=" boot option
Kernel panic - not syncing: VFS: Unable to mount root fs on
unknown-block(0,0)

This is strange because my grub is configured like this:

#XEN3.1-2.6.18
  title XEN3.1-2.6.18
  #root (hd0,4)
  kernel (hd0,4)/boot/xen-3.1.gz dom0_mem=262144
  module (hd0,4)/boot/vmlinuz-2.6-xen root=/dev/hda5 ro console=tty0

I say "strange" because I have a slack partition (is logical
partition)
that start well and is configured like this:

  title Slack-2.6.21.5
  root (hd0,4)
  kernel (hd0,4)/boot/vmlinuz-huge-2.6.21.5 root=/dev/hda5 ro vga=773

XEN kernel is installed under this slack partition, so root option is
correctly.

You can help me?

TNX
