Subject Re: Cannot add vm to any host in any cluster - error: "Unable to apply dhcp entry on router"
Date Sun, 22 Jul 2012 23:52:16 GMT
Might be a silly question – have you checked that your Pod, Clusters and Hosts and all enabled
and in a managed/contactable state?

Hi:

I can’t add any VMs to any hosts in my 3 cluster, two host cloud.

In one attempt, the GUI basically says:

   Unable to create a deployment for VM[User|i-2-7-VM]

Here is small part of the attached management log snippet.

How should this be fixed?
Can the problem be fixed from the GUI?
Please advise.
