During the weekend VMware released the first Update pack for its vSphere platform.
Update 1 (build 208156) is extremely important as it introduces support for the just released View 4.0.
It also introduces support for:
- up to 160 virtual machines per host (only in HA clusters with 8 hosts or less)
- Windows 7 and Windows Server 2008 R2 (both 32/64bit) as guest OSes (and as platform for the vSphere Client)
- IBM DB2 as backend database for vCenter Server 4.0
The Update 1 also introduces a new Pre-Upgrade Checker Tool, which can be executed on the ESX hosts to find out issues that may prevent the upgrade.
