Ubuntu – Possible to use LVM partitions inside a vmbuilder created KVM virtual machine

kvm-virtualizationlvmpartitionUbuntuvirtualization

I have an Ubuntu 9.10 host system with LVM partitions running KVM. I've been creating VMs using vmbuilder using LVM partitions for each VM instead of files for the VMs.

When I configure a VM using vmbuilder –part, the partitions in the file I'm using are created as regular partitions (sda1, sda2, etc.).

What I'd like to do is use LVM inside of the VM in case I need to resize the partitions at some point. But I don't see any options for doing that using the vmbuilder tool. It seems like this might be a common request to avoid using kpartx, etc.

Is there something I'm missing, or is this just not possible with vmbuilder?

If the partition is in qcow format you can use like 

qemu-img resize partition.qcow2 +5GB

and then 

kpartx

in the guest.
