Fedora xen - May 2006 - Adding more space to the system withou using LVM in the host

Hi,

I''ve a few Virtual Machines running FC5, the host is also FC5. I want
to
add some hd space to one of the VMs, and as  they are using LVM, I think 
it shouldn''t be so difficult. This is the line configuring the harddisk
for the Xen VM:

disk = [ ''file:/mnt/md0/xenM/autillo/autillo1,xvda,w'' ]

How do add other xvda? I want to create, for example 
/mnt/md0/xenM/autillo/autillo2 and add that space to the LVM in the VM. 
How should I do this? Maybe the solution is to export autillo2 as 
/dev/hdX or /dev/sdX?

How should I format the file using mke2fs? Thanks a lot and sorry if the 
questions are easy to solve, but I''m still not clear about that things!

Thanks Kwan,

I''ll try that tomorrow.

Regards,
Ignacio.
