Hyper-V server 2012 R2 – or the free hypervisor that can do it all…

You probably already know about vSphere Hypervisor (ESXi), the free hypervisor product from Vmware. Some of you may already be using it, either for testing or in smaller scale production deployments.

The case of the missing performance counters in VMM…

I upgraded a Virtual Machine Manager (VMM) 2012 installation to SP1 a little while ago, which since the base OS of the server was Windows 2008 R2, involved uninstalling VMM, upgrading the OS to 2012 and then installing VMM 2012 SP1 on the server. Since then, the counters for CPU, Assigned Memory and Memory demand … Continue reading The case of the missing performance counters in VMM…
