When I first downloaded Windows 8 Developer Edition and Windows Server 8 Developer Edition, I haven’t been able to boot the iso and install these new OS. I needed to install it on a physical machine, or vmware fusion and tyhen P2V to my XenServer 6 Beta Project Boston
Then I found a very cool tip on Thomas Koetzing blog :
You must create a VM with a Win7 template and copy the virtual machine UUID from the general tab in XenCenter or use xe vm-list in the CLI. Next you need to run the command xe vm-param-set uuid=<VMUUID> platform:viridian=false
Once you’ve done this modification, you’ll be able to install Windows 8 all edition.
And then if you want to install the Xentools, you can do it simply by mounting the xentools iso and right click the xensetup.exe file and chose properties. On the Compatibility tab, change the compatibility mode to Windows 7. Everything ran smoothly for me and Xentools works on my two Windows 8 vms
