Has anyone here used REAR
 

I am trying to configure Relax and Recover on OEL 5.5, however its a guest X_86 OS on top of a I_636 arch Oracle VM server 2.2.2. need help

We'll be glad to help you...so why don't you tell us what actual PROBLEM you're having???

Otherwise, the configuration guide and their documentation would be a good place to start:

I tested REAR a few months back. Liked the concept, but the implementation and doco is lacking.
I was never able to get a valid restore on the CentOS test system, so I abandoned the project. Another poster here on LQ had also mentioned difficulty with the restore after I suggested REAR as an option - hence I decided to test it myself.

As mentioned by TBone, describe what issues you are having.

@TB0ne..Apologize for the vagueness of the question, I 've didn't know where to start.

I am working on OVM hypervisor running I636 arch OVM server 2.2.2. On top of that i had installed OEL 5.5 X_86 OS. The backup solution is EMC networker, I have input appropriate "nsr" agent in rear config. i am able to run and generate rear recovery iso file. However when i try to upload the iso file onto Oracle VM manager 2.2.0, I realize that the guest is paravirtualized. By the below o/p i understand its paravirtulized.
When i select paravirtulized option, its asking me for an NFS path from where it would load the ISO, I did that and isin't working. I was told that the ISO file has to be unpacked, did that too and still no use. I am sure i am going wrong somewhere.

REAR works well on standalone physical machines, but this is an OVM not sure if REAR is built for a bare-metal-restore for Oracle VM.

No worries...but since you've got vm servers, back one up, and spin up a new vm to see what happens.
