Hi,

Clustering basically is just done for availability purposes. So, it is simply not possible to span a single VM over multiple hosts.

A VM can only run on a single host at any given time and can therefore never utilize more resources than this host can provide. DRS is only about balancing multiple VMs over multiple hosts, so you don’t have a one host being beat down by a couple of resource-intensive VMs while other hosts are idling around all day. A Single VM cannot be running simultaniously on more than 1 host.

The closest you will get is FT , where the VM is essentially Log shipped to a VM that resides on another host So what happens is that if the source Vm fails then the ghost one becomes live.

So like microsoft clustering solutions , you are just clustering for availability and not for performance.

Cheers

I have a couple of thorough EE Hyper-V articles that may help:

No, one cannot span a VM across nodes in a cluster.

2GB of physical RAM on a box? Is that available RAM after all of the other VMs or actual physical RAM?
