So is he just wrong? Probably, however your going to need to find out if you have the entire dm_* family for the functionality that you want (i.e. snapshots). You should (on your VM) simply be able to install lvm2 via yum, apt-get or whatever packaging mechanism is provided by your distribution. I use lvm2 on literally hundreds of paravirtualized Xen guests without a problem. A word of warning, don't make LV's (or their snapshots) a prerequisite to boot .. since you have no control over your initrd. If your provider has given you xvda and xvdb , use xvdb for your pv, keep the root file system on xvda.
