Rudi,
conv=notrunc prevents dd from truncating the file. Normally, dd would
just overwrite the file. When using conv=notrunc, dd will leave the
existing data alone and stop taking on 0s when the desired file size

Great, so existing data should still stay the same then?
Setting up LVM inside of a VM is the most useful in cases where you
give the VM direct disk access. Since you have a file (or a series of
files), most of the advantages that LVM affords you are redundant.
Ok, so you're saying that when I setup the VM's / dum_U's, and I get to
the partitioning part, that I should use LVM? Even thoug h LVM is
already being used on dom0 / the main server's hard drives? That sounds
odd to me, but I'll give it a shot on my next VM deployment
Since you're using LVM, you'll have to expand your LVM partitions
before you can expand the underlying EXT2 file system. As indicated
earlier in this email chain, you can expand your LVM group via
pvresize and lvextend.
My main system still has plenty space on the HDD's, and I use image
files for the VM's, not seperate LV's / PV's - The only reason I use LVM
is to make it easier to upgrade the HDD's
