HA configuration errors on virtualised ESX ESXi

ESXi5 HA High Availability vmware

If you are running a copy of workstation for your vsphere lab and you are encountering an error when trying to enable HA/DRS clusters then this is probably the issue.

When you create a ESX vm, vmware workstation autocreates a vm with 2GB’s of ram which is the lowest amount you can get away with to boot the hypervisor. However in order for HA to work you will need a minimum of 2300megs of ram (2.3GB) so shutdown your ESX/i vm and up the ram by 300megs or more and you will find that HA/DRS works correctly!
