I guess I am trying to do something unusual :)

Any thoughts?

I am sure there are lots of people using LVM or something similar. You can mount and edit files in LV partitions. Have you looked into LVM snapsnots to handle the second part of your idea?

Are you asking for instructions on how to use LVM to do this or are you asking if it is possible to do the mounting and editing?

Please clarify and I am sure you will get better responses, pointers, and tips.

Regards,
Todd

Hi list,

I am experiencing with xen on centos5 and so far everything is going well, I am really pleased. The domU have a dedicated LV (/dev/vg1/xenVM1, /dev/vg1/xenVM2 etc) and the guest OS is Centos4. At guest install time I have choosen to use LVM so that also inside the guest I have /dev/vg0/root, /dev/vg0/tmp etc. Is there a way to mount and edit the guest filesystem to customize files etc?
The idea would be to have a guest template that can be cloned and then edited to generate new VMs.

Thanks, have a good weekend

Simone
