I'm reading over documentation for esxi4 that states a vm can only have a single vcpu in order to support ft. Is this still true with esx4.1? I'm thinking the most important servers that would be worthy of ft would more than likely have more than one vcpu.
yes, a single vCPU is only supported, and will only work for FT
As it currently stands, yes. This is something that I have heard they are looking at overcoming in the next major release.
You will find all the requirements for FT on ESX 4.1 at http://pubs.vmware.com/vsphere-esx-4-1/wwhelp/wwhimpl/js/html/wwhelp.htm#href=availability_guide/r_f...
