Surely there are others who could answer this better than I can, but let me get it started.
PowerVM is basically what we've come to know on IBMi as a guested LPAR. PowerVM runs on a POWER box (POWER6 or POWER7). That POWER box will probably also be running IBMi or AIX as it's host operating system. You usually manage your PowerVM's with HMC. You don't directly attach disk or ethernet, DVD or other devices to PowerVM, all that is done through the host or VIOS (Virtual I/O Server).
Take a quick look at this redbook http://www.redbooks.ibm.com/redbooks/pdfs/sg247940.pdf
for more info.

Subject: What platform does PowerVM run on?
IBM advertises 3 PowerVM editions:
Looking at the feature list for each makes it sound like PowerVM runs on the HMC. Others have said that the HMC runs Linux. Why does IBM advertise PowerVM under IBM i? What platforms run PowerVM? Is PowerVM the software that drives the HMC?
