Those who thought (as I did until a few weeks back) that there would be no more Virtual Server development as Microsoft focuses its efforts on Hyper-V may be interested to hear that they have just announced an update for Virtual Server 2005 R2 SP1, providing host and guest support for Windows Server 2008, Windows Vista Service Pack 1 and Windows XP Service Pack 3. Further details can be found in Microsoft knowledge base article 948515.
In addition, Microsoft has shipped service pack 1 for Virtual PC 2007, providing guest support for Windows Server 2008, Windows Vista Service Pack 1 and Windows XP Service Pack 3 as well as host support for Windows Vista Service Pack 1 and Windows XP Service Pack 3. Further details can be found in the accompanying release notes.
Both of these products take the VM Additions version to 13.820.
This information has been floating around for a few weeks but was under NDA until yesterday. Watch out for more news from the virtualisation labs in Redmond soon…
