Yesterday I showed you how my Windows Server 8 Hyper-V lab is currently built (I’m in the process of wiping to build something more flexible). Today, I’m going to show you two things:
- Not just Live Migration in action, but simultaneous Live Migration. I’ll be moving all 66 VMs from Host1 to Host2, and they’ll move 20 at a time. This is a huge improvement over the 1 at a time that we can do in W2008 R2, and way more than the maximum of 4 (on 1 GbE) or 8 (on 10 GbE) that vSphere 5.0 can handle. BTW, I was moving all of them at once last night
- I’m going to perform the move by draining Host1 using a new pause function. This is used for host maintenance (similar to VMM maintenance mode) and will Live Migrate the VMs to the most suitable host (Failover Clustering measures memory, where VMM does Intelligent Placement). This pause function is used by Windows Server 8 Cluster Aware Updating.
In the demo, you’ll see my 20 GbE NIC team that is used for Live Migration and the 1 GbE file server where the VMs are located:
