Need to check that how many vcpus are available on a compute node for vm instances.
For example:
$ nova hypervisor-list
+----+------------------------+-------+---------+
| ID | Hypervisor hostname | State | Status |
+----+------------------------+-------+---------+
| 1 | hos5-cp1-comp0001-mgmt | up | enabled |
+----+------------------------+-------+---------+
$ nova hypervisor-show 1
+---------------------------+------------------------------------------+

You will get those information in Openstack Dashboard,under admin--> system-->hypervisor
