Re: [Xen-users] lomount + lvm

[Brian Krusic <brian@xxxxxxxxxx>]

Hi Ryan,

I create my VMs using the virtual manager gui in Centos.

I then simply use an installer CD when prompted and an xvda type img  
file is created (I usually don't allocate all space during the  
creation).
During the OS installer phase (Centos/RHEL), I create default  
partition layouts which use LVMs.
So at the end, I have this img file that I can't figure out how to  
mount.  I know that within that img file, that partition 2 is the root  
fs which is what I'd like to lomount.
