Re: [Xen-users] Target filesystem doesn't have requested /sbin/init.

Hello.

Mount your VM6.img as loop device within Dom0, check if it is consistent 
and /sbin/init is there.
Also, within BusyBox you can check what is mounted as "/" and if it's 
readable.

Should not. Xen guest VM without kernel and/or bootloader is a normal 
case. Although, usually you wish to install the same kernel image (via 
your guest's regular package managing system), as on your Dom0, in order 
to have the right /lib/modules.
> Also, how can I install a bootloader to the guest image?
Normally you don't install bootloader in a guest VM, unless it's HVM 
(your is PV).
It is possible to boot the guest VM using kernel stored in guest's 
filesystem, but the bootloader will not reside within guest image. 
Instead, in case of Xen, you use a small program called pygrub within 
Dom0. It reads the image, extract the config, the kernel and initrd, 
then boot them. Check pygrub's documentation, usually it works fine.
On the low level, the booting process is pretty much the same as if you 
were using kernel and initrd from Dom0 filesystem. The difference is 
that you don't actually have the needed kernel image in Dom0, it's 
extracted on the fly from DomU's image just before booting.
