Description

Trying to add a kvm host in basic zone.
Failed after time out occured.
Checked the agent log in KVM host, seems like conflict occurring with storage pool.
Tried removing the storage pool and re-installing the cloudstack agent.
Even then failing on the same error.
Here is the cloudstack agent log in kvm:
