Gerben’s Blog on Virtualization

Virtualization is becoming a standard

MS Virtual Server R2 SP1 RC available

Posted by Gerben on 19/4/2007

The Release Candidate build of Virtual Server R2 SP1 is now available Before anyone posts a comment, yes I’m aware that we said we planned to have SP1 out in the first quarter and it is April now, so we’ve missed that. You’re welcome to speculate on the final release date.
The download site also has a ReadMe file which details how to make Virtual Server work on Windows Vista (something which has caused a few headaches, although is now documented in other places) and gives a history of "What came in with R2" and "What is new with R2 SP1" – the list is as follows
  • Support for hardware-assisted virtualization
  • Support for greater than 64 virtual machines on x64-based hosts
  • VHD Mount command-line tool and APIs
  • Tested for interoperability with SCVMM Beta 2 RC
  • Interoperability with Volume Shadow Copy Service.
  • Support for additional Guest and Host Operating Systems
  • Service Publication using Active Directory Service Connection Points
  • Host clustering whitepaper
  • Virtual SCSI fix for Linux guests
  • Larger default size for dynamically expanding virtual hard disks
  • VMRC ActiveX control and Internet Explorer Security Zones
  • IVMGuestOS::Get_OSName property returns more operating system information

Each of these is explained in the Readme.

I suspect there will be quite a lot of interest around VHDMount as we move to release. When beta 2 was out Dave Northey blogged how to install VHD Mount without virtual server (the instructions seem to have gone from the current release notes and I haven’t tested them) and Ben Armstrong posted a guide to making VHDs mount when you double click them.
Download it here, if you’re not preregistered with the beta program you have to register here first.
According to Ben Armstrong there are no significant new features in this release compared to the beta 2, mostly bugfixes.
