Quoting from the Lxlabs official announcement:
Lxlabs, the makers of the Lxadmin web hosting control panel, today announced the immediate availability of HyperVM 1.2, a multi tiered, distributed web based management software targeted at VPS hosting companies.
HyperVM, which currently supports openVZ, will support Xen and MS Virtual Server in the short future, and provides a very easy method for the hosting companies to setup and delegate their vps management, thereby providing the most effective way to monetize on the fast growing vps market…
As expected the market is starting to require and produce multi-platoform virtualization managers.
