Hi Experts,

Is the id the same as uuid for vms? I've checked it when I use qume to lauch 
vms. 
Dmidecode in vm console:
[root@10-0-0-6 ~]# ./dmidecode -t system
# dmidecode 2.10
SMBIOS 2.4 present.

You can see UUID is consistent with ID. 
My question is: If I use ESXi or XEN as hypervior, is it always correct by this 
way? Currently I'm just using QUME to lauch vms.


Best Regards!
