title: CloudStack installation: Error creating instance
body: <p>I am a newbie to CloudStack. I installed it using Quick Install Guide on CentOS 6.4 and kvm. As my network is a LAN at my faculty and there is a DHCP and Gateway for connecting to internet, at the beginning I defined address pool of Pod and guest withing the range of LAN addresses. But I wasn't able to create instances getting this error:</p>
  
  <p>2013-06-17 13:44:03,445 DEBUG [cloud.storage.StorageManagerImpl] (Job-Executor-1:job-9) Insufficient un-allocated capacity on: 200 for volume allocation: [Vol[3|vm=3|ROOT]] since its allocated percentage: 2.2468850974329963E7 has crossed the allocated pool.storage.allocated.capacity.disablethreshold: 0.85, skipping this pool</p>
  
  <p>I guessed this is because of IP conflicts between pool and dhcp range. So I re-installed it (removed and re-installed cloud-agent and cloud-client), and this time defined a different subnet for address pools (255.0.0.0) from dhcp subnet (255.255.0.0). But now I'm getting this error while "Creating system VMs" after doing the configuration using UI:</p>

  <p>Is the problem related to IP conflict? If yes, how to solve it?</p>
  
  <p>Thanks</p>
