I now have a bit more of a handle on LVM2 and agree it's probably the way to go. You can enlarge your disc space with your machine powered down. NTFS won't see this and if it's a boot volume you cannot use MS diskpart to increase it. You can add virtual partitions in the freed space however. If you really want to enlarge your system (C:\) drive you can use GParted's ntfsprogs. Windows XP complains bitterly and requires a few reboots but gets there in the end. (At least you can do experiment with confidence on a clone machine-).
Fortunately I have no need for Windows servers, and can simply enlarge my file systems on the fly.
LVM needs hardware or software RAID (or both :-) .
Do you do LVM on the host or within the guests?If doing it on the guests, having snapshots as well as data backups means this isn't really an issue for me. If I need to upgrade the disk I can do so with dd, then just add the new disk to the LV and drop the old one, right? Or it may be simpler to just clone the virtual machine to a bigger disk then enlarge the volume.
cheers, Peter.
