Re: [Xen-API] Uniqueness of UUID(s) across hosts

[Guo Lian Yun <yunguol@xxxxxxxxxx>]

Hi, Saurabh
when i performed migration from one server to another by xm command,the uuid of the vm on the destination is the same as the source.I think it is similar to Xen api.
There is a live migrate reference, maybe help to you!

(See attached file: live Migration.pdf)

Best,
Regards

Subject	[Xen-API] Uniqueness of UUID(s) across hosts

Hi,

I'm trying to associate some xen api objects, and have some queries on 
the same. It'll be great if someone can provide some information.

As per the api documentation for Xen 3.1, (API version 1.0), the uuid 
for an object is guaranteed to be same across multiple sessions. 
However, if I have a cluster of xen-servers installed, is it guaranteed 
that there will not be any conflicting uuids across them (for any of the 
api objects) ?

Also, when I live migrate a vm, will the uuid of the vm (and its 
associated objects) on the target server be same as they were on the 
source server.

Thanks,
Saurabh.
