Hi All,

I am new to LDom concept. I have some questions about snapshots using LDom.

1: IIUIC, Each Ldom can be treated as virtual machine(vmware.. not
exactly same but quite similar) with its
own guest os etc. Does it also support features like snapshot ? Can
snapshot be taken when machine is running ?  Or do we have to
shut it down or at least suspend and then take the snapshot ?

2: Also  from what i have read so far about LDom, we can use
file,normal hard disk, LUN exported from filer as 'disk' in LDom. So
What kind of snapshot possibilities we have got here ? Can we snap the
entire LDom (including ldom configuration, guest OS data,
memory state) in each of these cases ? Here is what i think but i am not sure.

When disk is file based , it is possible.
When its normal disk and have some file system like ZFS or volume
manager which supports snapshot , it's possible.Otherwise its not
When its LUN from filer , if filer has snapshot capabilities , it is
supported. otherwise not.

Also my question would be, does LDom admin tool takes care of these
snapshot work in the back end? Or it is the user's responsibility
to manage all these different snapshots.

3: What is the preferred way  to take LDom snapshots in community ?

4:Does Ldom have suspend and resume support at machine level ?

5: Is there any way for third party application to access these
snapshots and memory state ? Is there any too/library which provides
interface for accessing such snapshots and other machine state (e.g
memory in case of hibernation). Any links ?

Thanks,
Rohit
