I am trying install open stack on scientifi linux 6.3(64 bit) using manual " http://docs.openstack.org/icehouse/install-guide/install/yum/content/ch_preface.html%22 (http://docs.openstack.org/icehouse/in...) . i setup with a controller , and compute node seperately, i requested a vm with ubuntu image from controller to run on compute node, its took nearly 1hr then i got status as error when i see $nova list . is there is a way to check that actually vm is booted or is request sent to compute node from controller ?

You'll want to start by listing the instance to see what the status is:

nova list

Find the instance ID then:

nova show {UUID}

If it is in an error state you will usually see a trace message in the output. If it is "running" then you can see what the status of the instance is by looking at the console log:

nova console-log {UUID}

Since your instance is in an error state you will need to figure out what went wrong. If the trace in nova show doesn't have enough information then you'll need to look at the logs in nova-compute on the compute node. You can see which compute node Nova tried to deploy on by looking at the Hypervisor section in nova show.
