IDC released a report this morning entitled “Virtualization Continues to See Strong Growth in Second Quarter, According to IDC”…  Among the data they report Virtualization licence shipments in Q2 of 2008 increased 53% year over year.  Vmware holds the largest market share at 44% (combined VMware ESX and VMware Server) however Microsoft now holds a market share of 23% (combined Hyper-V and Virtual Server).  Back in October of 2006 IDC reported the Microsoft Virtualization share at a whooping 8.6% and in September of 2007 it was reported the Virtual Server market share was around 7%.  So since this is my blog (hence I can draw any conclusions I want) I’ll say Hyper-V took at least 16% market share in one quarter.

Any way if you want to read the full report go take a look at (it’s on the front page).
