Fedora xen - Jul 2007 - Kernel panic - not syncing: Attepmted to kill init!

Hi,

While I use "xm create -c guestvm" to create the domain at Fedora Core
6,
the following error msg appears:

Kernel panic - not syncing: Attepmted to kill init!

This never happened before, when several guest domains are running with
CPU usage < 5%, and I was trying to create a new one. This time, the CPU
usage of the running guest domains are 25%, much higher than before, and
above error msg appears while I create a new guest domain. Is this due to
the reason of not enough resource can be allocated to the new domain? Any
clue?

Thanks.
Best

Did you recently update the kernel? And get a new initrd as well?

I ask because from what I''ve seen, this is a common problem. When you
update the kernel (and a new initrd is created), the initrd doesn''t get
built to include the xenblk.ko driver.

You can check by unpacking the initrd into a directory using this command:

gunzip < /boot/initrd.img |cpio -i --make-directories

Create a new directory first, cd to the directory, run the above command.
Look at the init script. Does it have the following lines in it?

echo "Loading xenblk.ko module"
insmod /lib/xenblk.ko

If not, you''ll need to move xenblk.ko into the initrd directory
(correct
version of course), add the above lines and repack the initrd using this
command:

find . | cpio --quiet -co | gzip -9 > /boot/initrd-XXXXX.img

Just went through this (again) so it''s fresh in my mind. I tried using
the
mkinitrd command to create a proper initrd in the domU but couldn''t get
it
to add the xenblk driver for some reason.

If the above isn''t the problem, I''ll bet it''s
leprechauns.
