HI Venkat,

Which hypervisor you are using  and also check the agent log in case of KVM.

For xenserver ,check the SMlog . for  that exception it will clearly tell you the reason for

Mostly it will cause t due  to problem in  ssh key file ( if  router is not reachable from
host) or   no space left.

So check the  router is accessible from the host/as well  as capacity.

Hi All, 

when we are trying to  spin a instance getting the error is  "Unable to start a VM due to
insufficient capacity" so we have checked storage and RAM it's look enough room place in host.

*And also we have checked the management server log we identified that below error message

2016-04-05 06:01:35,974 INFO  [c.c.v.VirtualMachineManagerImpl]
(Job-Executor-114:ctx-9e73f683 ctx-419ad956) Unable to contact resource. Resource [DataCenter:1] is unreachable:
Unable to apply userdata and password entry on router 

In this scenario we have rebooted the respected Virtual Router(VR) and then spin a instance
successfully deployed. 

We are thinking that rebooted is not permanent solution and    also not good habit. 

Please guys if anyone facing this situation Please share the proper solution without any impact
on existing instances.
