If you need to reduce the size of one of your logical volumes being
used for a VM in order to give it to another VM, you'll need to
shrink the filesystem inside that VM first. That is supposed to be
possible, but it could get tricky, so it seems like a better idea to
me to only assign as you need to, and not start off assigning all
your LVM space to your VMs just because it's there.

Hi,
I'm only trying to see if I got the idea. Right now, I've a
physical machine, with FC5 and one FC5 guest running. I'm using a
file as VBD for the guest, and want to know exactly how the LVM
stuff works on Xen. I've a spare 40Gb partition, so imagine I
create a LVM volume on that partition and then I split the space
into 3 logical volumes. As I need to install 3 VMs on the machine,
will I be able to easily resize the partitions, so for example if
suddenly I need 10Gb on one of the VMs I can "stole" that Gbs of
other VM?
Thanks for any reply, as I'm a little confused!
