Virpus has undergone a revision. Previously, it provided OpenVZ VPS, but now, it only provides Xen VPS and Cloud VPS. Virpus was founded in 2006 and is a US hosting company with a long history. I have used OpenVZ VPS before, which was very average. Now Xen VPS and Cloud VPS seem to be good. Virpus' Cloud VPSs are all SSD hard drives (not yet available).
Below are Virpus Xen VPS configurations and prices:
