InsufficientServerCapacityException - Unsure Why

[Elliot Berg]

Hi,

I've been putting together a cloudstack set-up for experimentation 
purposes - right now we're just trying to compare different platforms 
for private cloud infrastructure before we start getting too in depth 
with any of them.

I've added the cloudstack 4.2 apt repository, and I'm running on Ubuntu 
12.04 LTS, and I believe I've followed all the installation guides 
correctly at the various stages.

We've set up a management server, which is also an NFS server, however 
we're interested in using local storage for the majority of things, and 
have also set up a single KVM host which I believe is all configured 
correctly to use local storage. If I look at the dashboard, I'm told I 
have more than enough resource in every section to create an instance 
the size I want to - which is a small offering I've created with just 
1.0GHz and 1GB of RAM, with local storage. The host's not very powerful, 
but according to the dashboard I am using 1.50GHz/5.87GHz, 
1.38GB/7.80GB, 3.55GB/285.95GB Secondary Storage, 1.03GB/450.99GB Local 
Storage and 0.00KB/571.90GB Primary Storage (I'm assuming that's meant 
to be a combination of the NFS server's primary storage offering and the 
local storage on the host, though the numbers don't quite make sense at 
first glance).

However, when I try to add an instance, I receive an 
InsufficientServerCapacityException and I'm struggling to work out why. 
I can't add an instance using a small shared storage offering either, 
but if I'm not mistaken that's expected because the zone and host are 
configured to use local storage. The only thing I can think of is that 
the local storage isn't properly configured, but when I've looked it 
seems to be.

Any pointers for how I can further diagnose this would be great - thanks 
in advance!
