Hi all.
I wanna try Xen to compare it face to VMWare and face to QEmu but
I''ve a
little problem.
I''ve installed it correctly - I think - and define in the grub.conf
file
the following entry :
title Xen 2.0 / XenLinux 2.6.10
root (hd0,0)
kernel /xen.gz dom0_mem=131072
module /vmzlinuz-2.6.10-xen0 root=/dev/hda1 ro console=tty0
My Linux main partition is on hda1.
Files xen.gz and vmzlinuz-2.6.10-xen0 are present on /boot (I must also
highlight a problem in Xen documentation taht say to write /boot/xen.gz and
/boot/vmzlinuz... in the grub file. But when specifying /boot grub
don''t
find the files).
The problem is that Xen kernel boot (xen file is find) and apparently
vmzlinuz too but reboot after some few seconds. The only message I can read
is :
Kernel Panic : Syncing no init found try passing init= option to
kernel
Anyone have an ideas about that ??? What initrd image must I set to solve
this ?
What debug informations can I give you to detail more accurately the
problem ?
Thanks.
JB

Re: [Xen-users] Problem when booting Xen for the first time.
Simple answer: your root= option is wrong, it should probably be root=/dev/hda2 or similar. If your xen.gz and kernel image files live in /boot and grub can find e.g /xen.gz rather than /boot/xen.gz on hd0,0, then you will find that your Linux installation has a separate /boot partition (hda1) and the root partition is elsewhere (e.g. hda2). Boot into native Linux and run "mount" to see. The root partition (mounted as /) is the one you want to use with root= on the kernel command line. The documentation isn''t wrong, it shows a typical example which will vary with particular configurations.

Re: [Xen-users] Problem when booting Xen for the first time.
I suggest taking the extra ''z'' out of ''vmzlinuz'' as a start :) It should be vmlinuz not vmzlinuz Jack B wrote:> Hi all. > I wanna try Xen to compare it face to VMWare and face to QEmu but I''ve > a little problem. > I''ve installed it correctly - I think - and define in the grub.conf > file the following entry : > title Xen 2.0 / XenLinux 2.6.10 > root (hd0,0) > kernel /xen.gz dom0_mem=131072 > module /vmzlinuz-2.6.10-xen0 root=/dev/hda1 ro console=tty0 > > My Linux main partition is on hda1. > Files xen.gz and vmzlinuz-2.6.10-xen0 are present on /boot (I must also > highlight a problem in Xen documentation taht say to write /boot/xen.gz > and /boot/vmzlinuz... in the grub file.

But when > specifying /boot grub don''t find the files).The Xen documentation is not wrong. It describes a case where /boot is in the same partition as /, whereas in your case your seem to have /boot on a separate one.
