Re: [Xen-users] exec of init (/sbin/init) failed!!!

[dasari dakshina <dakshi80@xxxxxxxxx>]

A small observation :
disk = [ 'file:/root/vmrootfs,sda1,w']


Where as 
in these steps u have

dd if=/dev/zero of=vm1disk bs=1k seek=2048k count=1
> 
> mkfs -t ext3 vm1disk
> 
> mount -o loop vm1disk /mnt


So shouldnt it be something like 
disk = [ 'file:/root/vm1disk,sda1,w']

Just my thougts ..
