Installing CentOS on Citrix Xen hangs: mounting /tmp as tmpfs

Problem: If you use one of the non CentOS templates on Citrix Xen 6.2 when installing CentOS, it hangs during the installation at mounting /tmp as tmpfs

Solution: Create the new VM but don’t boot it yet. Log into the Xen server as root and run the following command

xe vm-param-set uuid=”$VM_UUD” platform:viridian=false

Now boot the installation again.

Note: You can get your UUID from the properties tab in the xencenter front-end.
