  • 1.  Duplicate HostUUID for Citrix Servers

    Posted May 18, 2017 04:40 PM



    I have a few servers that appear to have a duplicate HostUUID, however even when I delete and recreate it, these computers are still showing duplicity. The history of one of these computers is, as follows:

    It looks like these are all Citrix Servers, it might have something to do with it. When I delete the HostUUID and force the regeneration/recollect, it looks like it changes for all computers.


    However, when I'm logged at these computers, the UUID is different for each.


    Any ideas?


    Thank you

    The host UUID is calculated using several values including Serial number, system ID etc. If any of these change frequently (due to the guest moving to another host in the cluster) then you need to lock the HostUUID to prevent it changing.
