The host name is now automatically set to the virtual machine name when using the Run Once dialog for a virtual machine. The name can be changed if required. The Run Once sections is the VMM Guide should be updated to note this.
" VM Hostname The host name of the virtual machine. It is set automatically to the name of the virtual machine, but can be changed. " looks fine to me. Thanks
