["Michal Mihalik" <michal.mihalik@xxxxxxxxxxxxx>]

Hi

  I am trying to get this thing running xen 3.0.2.

 I instaled into my debian

linux-image-2.6.16-1-xen-686

xen-hypervisor-3.0-i386

xen-tools

xen-utils-3.0.

etc.

 

 

succefuly booted dom0 and creted domU.

but I am unable to find why i do get this...

 

with this config I must manualy insert loop into kernel.

 

>kernel = '/boot/vmlinuz-2.6.16-1-xen-vserver-686'
>memory = 96
>name   = 'testvm'
>root   = '/dev/hda1 ro'
>disk   = [ 'file:/vserver//domains/testvm/disk.img,hda1,w', 'file:/vserver//domains/testvm/swap.img,hda2,w' ]
>dhcp = "dhcp"

 

and I get this

 

>Registering block device major 3
>.....

>Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(3,1)

or this config

 

>name="tc"
>kernel="/boot/vmlinuz-2.6.16-1-xen-686"
>root="/dev/sda1"
>memory=128
>disk=['phy:VG0/domU_tc_system,sda1,w']

># network
>vif=[ '' ]
>dhcp="off"
>ip="10.1.24.250"
>netmask="255.255.248.0"
>gateway="10.1.24.254"
>hostname="tc_new.petitpress.sk"

>

>extra="3"

i get the same error

 

>Registering block device major 8
>.....

>.

>Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(8,1)

heeelp I googled all nigh and nothing.

 

Thanks for help.
