Windows 7, Server 2008 'Convenience' update is anything but – it breaks VMware networking
VMware is warning administrators to steer clear of an official update for Windows 7 and Server 2008 – after the patch was found to be incompatible with some virtual machines. The virtualization house says that VMs using VMXNet3 virtual NICs are having networking problems after installing the Windows 7 rollup update. VMs running Windows Server 2008 R2 SP1 are seeing similar problems, prompting VMware to recommend that anyone running either OS in their VMs on VMware vSphere should avoid installing the Microsoft rollup until a fix can be worked out.
