Marcus Sorensen commented on CLOUDSTACK-205:
--------------------------------------------
Executing cmd: lsmod|grep kvm
If you do that before the install, do you find the module? The KVM module is a
part of the host requirements prior to install, but perhaps we can try to mod
probe or something to avoid future issues. My guess is that it is being
installed as a dependency when the agent is installed and only gets loaded by
reboot.

> Key: CLOUDSTACK-205
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-205
> Project: CloudStack
> Issue Type: Bug
> Components: Install and Setup, KVM, Management Server
> Affects Versions: pre-4.0.0
> Environment: Management server : Rhel 6.3
> Host : KVM (Rhel 6.3)
> ASF build :
> http://jenkins.cloudstack.org/job/build-4.0-rhel63/163/artifact/CloudStack-oss-4.0.0-163.tar.bz2
> Reporter: Abhinav Roy
> Fix For: pre-4.0.0
>
> Attachments: agent.log, api-server.log, management-server.log
>
>
> Steps :
> ==========================
> 1. Deploy an advanced zone on a fresh CS setup.
> 2. Install agent on a freshly configured KVM host (Rhel 6.3)
> 3. Add host to the management server.
> Expected Behaviour :
> ==========================
> The KVM host should be added successfully to the MS.
> Observed Behaviour :
> ==========================
> While adding a KVM host (Rhel 6.3) to the management server we are getting
> this error and the addition of host fails:
