When creating the VM in virt-manager, in the last step you can select a checkbox 'Modify configuration before install'. When you do that you will see the configuration dialog for the VM and there on the Overview tab you can also find the UUID. I haven't tried that but that way you may be able to create the TMP directory in advance. Hope this helps,
