[Xen-devel] Problems with loopback and sda1

[Rune Johan Andresen <runejoha@xxxxxxxxxxx>]

Hi, my pysical HD is mounted on the logical sda1. When i try to mount 
the loopback on something else than sda1, xm complains. 

With:
disk = [ 'phy:loop0,xda1,w', 'phy:sda1,sda1,r' ]
root = "/dev/xda1 ro"

I get error msg:
>>error begin
VFS: Cannot open root device "xda1" or unknown-block(2,0)
   Please append a correct "root=" boot option              
   Kernel panic: VFS: Unable to mount root fs on unknown-block(2,0)
>>error end


Does Xen deny use of anything else than logical sda1 for HD? When my 
physical HD is sda1, how can I use another logical drive for my loopback? 

To save space I want to read-only mount my pysical HD from the loopbacks.
(If I try to mount sda1 now, I mount the loopback, not the pysical HD) 

Cheers,
Rune
