[Users] Questions about ovirt engine

Hi, I created a VM in my engine. And I found that every time I run the VM after shutdown, the VM uuid was changed to a different not while the VM itself was not changed including the VM name. Why doesn't engine keep the UUID for a VM and use the UUID every time the VM starts? How can I persistent my setting to a VM with "vdsClient", like the password set by the "setVmTicket" command? -- Shu Ming<shuming@linux.vnet.ibm.com> IBM China Systems and Technology Laboratory
