Thank you Carlos. I will try all the option you mentioned.
Glad to learn additional options.

Hi Prakashan,
There are different options to control the placement of the VMs.
If you want to manually deploy them, you can hold the VMs (onevm hold<id>). The
scheduler won't place these machines, but you can still deploy them with onevm deploy.
Or you could start only the OpenNebula daemon without the scheduler (take a
look at the 'one' start script, and comment the ONE_SCHEDULER part).
The other option is to use the REQUIREMENTS and RANK VM template attributes,
see [1].
The scheduler will read them, and place the VM accordingly. You can require the
VM to be deployed in a specific host or cluster; or modify the RANK expression
to set the hosts priority.
Regards,
Carlos.

Hi,
I noticed that by default the scheduler automatically pick the host when more
than one hosts are available to deploy immediately after onevm create command.
The onevm deploy command only works when for some reason the scheduling goes
into pending state for a while.
I am looking for little more documentation on various options for deploying the
virtual images on the host of our choice. If someone can share the
configuration as to how they deploy OpenNebula in a cluster environment that
would be great.
I am using CentOS 5.5 64 bit with OpenNebula 2.0.1 and running Xen on the
cluster nodes.
Thanks,
Prakashan
