Perl: wrapper for virt-install to provide iSCSI storage pool creation

So I've been working on a setup for virtualization, where currently I'm using one large iSCSI target from an OpenSolaris machine. It occurred to me that there is a downside to this. I cannot use zfs snapshots for individual machines and backups/restores will be more difficult. I also did not want to be hassled with having to connect the iscsi targets using iscsiadm every time I spin up a new VM.

Kernel Virtual Machines using libvirt

I use iSCSI from a giant ZFS storage pool in order to setup virtual machines. There's a couple advantages to this, as you get the power of ZFS snapshots and the ability to grow your virtual machine's disks fairly easily. To make administrating things a bit easier, I use one large iSCSI target and put LVM on top of this. So really this article will apply to anyone that wants to use logical volumes for their disks, which is much preferred over using files.
