Apache cloudstack 4.5, secondary storage is 0.00 kb/0.00 kb

I am trying to do quick installation of Apache cloudstack 4.5 from:

http://docs.cloudstack.apache.org/projects/cloudstack-installation/en/4.5/qig.html

My both system VMs are up and running (two green circle), but in dashboard i am still not able to see space allocated to secondary storage and hence not able to download default template i.e. centOS 5.5. Please help me with this issue.

Thank you in advance for any help you can provide!!!

CloudStack Security group

Have been playing around with CloudStack 4.3 for quite a while and now i am experiencing problem with CloudStack Security Group.

Currently i am having trouble with a small Lab.

Account1 - VM1
Account2 - VM2
Accound3 - VM3

The required scenario was

VM1 and VM2 can communicate 

while

VM3 cannot communicate with VM1 and VM2

How do i set the security group? Under Ingress or Egress?

I appreciate some help to understand how it works too. The documentation on apache cloudstack wasn't very clear

Apache Mesos Vs. Apache CloudStack

Managing the infrastructure (private cloud or public cloud) at scale and ease is addressed by Apache Mesos, Apache CloudStack and OpenStack.

I have few questions in this regard and wanted to see if someone can throw light.

1) Any article(s) that compares and contrast the above?

2) Why run one over the other at all? (as I see from tutorials that one can run over the other)

3) It seems like CloudStack is centered around VMs (Hypervisor) and Mesos is centered around Scheduling and allocation of resources in side VMs for different co-existing software systems. Am I right in my conclusion?

4) If so, why does Mesos claims that it can manage bare metal boxes w/o even the need for Hypervisor? Is this for the reason for workloads that do not go well with VMs? (esp. LSM based systems such as SOLR-Lucene and HBase)

5) Is it with the choice of Linux VMs. Vs. Linux Container for resource allocation? IOW, Mesos is Linux container based framework, and CloudStack is Linux VMs based framework?

(PS: Please pardon me for not adding tag apache-mesos for this question. The tag does not exist, and I can't create one because of my lower scores)

(Update: Added one more point)
