How to determine virtual machine host name "virtual server"

Recently had a problem where the lab folks forget where my VM was installed to and I needed some RAM added to it.  I needed to find the physical host name of the machine the VM was running on.  Turns out that there is a handy dandy reg key one the VS devs pointed out to me:

 HKLM\Software\Microsoft\Virtual Machine\Guest\Parameters\PhysicalHostName

Hope it helps someone, I spent quite some time trying to figure it out on my own.

    For some reason that key doesn’t exist on any of our guests.

    Really? Is it HyperV and have you installed the guest VM tools?

    I google like crazy but no luck ! Where do you people find prebult vm host distros with xen virtualbox … like xenoppix vmknoppix and xen live cd that have prebuilt host vms but no installer included ! I have find some powerful opensource solution but these are all for class server enterprise solution and request a 64bit cpu ! I need support for for x86 – 32 bit cpu ! So if there is prebuilt 64bit solution where is then 32bit solution ! Im not interested in running os in os that can be easly done but in bare metal host hypervisor ! XEN server were good solution but will not install  due to long mode cpu support is missing that means 64bit support cpu ! ESXi will have a scsi hardware (not good) ! Aparently xen runs on PII cpu so whats the heck ! So if someone have knowledge of some useful links that were good ! I canot find eny centralized info page abaut prebuit host hypervisors and links !

    (get-item "HKLM:SOFTWAREMicrosoftVirtual MachineGuestParameters").GetValue("Host Name")

    You sure helped me!  I had created the new Hyper-V host in our new domain so I was unable to locate in our old DNS. Huge time saver.  You Rock!!!
