[Xen-users] Problem with Debian for create machine virtual from Centos

Hi...

My name is Bruno I want congratulation all of group.

My first  question about XEN . I have Centos with XEN installed.  I am
trying make an virtual machine Debian using virt-install, my options are:

[*root@xen opt]# virt-install *
*What is the name of your virtual machine? Debian*
* How much RAM should be allocated (in megabytes)? 256*
* What would you like to use as the disk (file path)?
/xen-lvm/debian-vm02/Debian-disk.img *
* How large would you like the disk (/xen-lvm/debian-vm02/Debian-disk.img)
to be (in gigabytes)? 10*
* Would you like to enable graphics support? (yes or no) no*
* What is the install location? /media/cdrom *
* *
So show start the message erro

Starting install...
Could not find an installable distribution at ''/media/cdrom''
Domain installation may not have been
 successful.  If it was, you can restart your domain
 by running ''virsh start Debian''; otherwise, please
 restart your installation.

Why XEN don''t continues installation ? There is incompatibilities
between
Centos 5.4 and guest Debian 5.0 ?

Ok.

Thanks

Re: [Xen-users] Problem with Debian for create machine virtual from Centos

I make change in mode for installation virtual machine (debian) now I am
using file with image of Debian 5.0 (
http://stacklet.com/downloads/images/debian/5.0) .

I create file Debian-VM01 ,  the content file is

kernel = "/boot/vmlinuz-2.6.18-92.el5xen"
ramdisk = "/boot/initrd-2.6.18-92.el5xen.img"
memory = 256
name = "debian-vm02"
vif = [''bridge=xenbr1'']
disk = [''file:/xen-lvm/debian-vm02/debian.5-0.x86.img,xvda,w'']
ip = "192.168.4.10"
gateway = "192.168.4.254"
netmask = "255.255.255.0"
root = "/dev/sda3 ro"
extra = ''4''

When I started the machine show this message error

Mounting root filesystem.
mount: could not find filesystem ''/dev/root''
Setting up other filesystems.
Setting up new root fs
setuproot: moving /dev failed: No such file or directory
no fstab.sys, mounting internal defaults
setuproot: error mounting /proc: No such file or directory
setuproot: error mounting /sys: No such file or directory
Switching to new root and running init.
unmounting old /dev
unmounting old /proc

Why I can do Debian recognize the virtual storage system of XEN ?

virt-manager or virt-install don''t support installing Xen PV guests
from
a CD/DVD/.iso, they can only be installed from network.

So you need to specify --hvm if you want to install Xen HVM (fully
virtualized/emulated)
guest from a CD/DVD/.iso.

Re: [Xen-users] Problem with Debian for create machine virtual from Centos

I had a similar experience when I tried to install on a system
in which CPU did not have support for virtualization.

Short story: you''re using Centos kernel and initrd for Debian. That
won''t work. Modern distro usually needs their own initrd.

How proficient are you with Xen/Linux? If you prefer mostly to use
GUI, then the easiest way is to use virt-install, create
fully-virtualized (HVM) Debian guest with install media from cdrom,
and convert it to PV (manually) later. To succesfully install HVM
guest you need CPU with hardware virtualization support
(intel-vt/amd-v)

If you''re familiar with chroot, apt-get, update-grub, and other
command line tools, it should be possible to create a suitable initrd
for your stacklet image.

This would probably be the best link
http://people.debian.org/~joeyh/d-i/images/daily/netboot/xen/xm-debian.cfg
> How I create initrd of Debian inside Centos ? There is site with this file
> for download ?
it generally involves:
- chroot
- install new xen-compatible kernel image with apt-get
- run update-grub (or whatever command necessary to create a good
/boot/grub/menu.lst)
- change your domU config to use pygrub bootloader instead of
specifing kernel and ramdisk. Or you could copy domU''s kernel and
ramdisk to dom0, your choice.

If the above seems to complicated, I suggest you try xm-debian.cfg first.
