Subject RE: Is Restart of the KVM host (rhel 6.3) required , before adding it to Management server in ASF 4.0 ?
Date Tue, 25 Sep 2012 20:56:53 GMT
Yes Rohit. Both times we had a fresh installation of both kvm host OS and management server.


Thanks and regards,

Hi Rohit,

I was able to deploy advanced zone setup with http://jenkins.cloudstack.org/job/build-4.0-rhel63/163/artifact/CloudStack-oss-4.0.0-163.tar.bz2
build.

But again I saw the below error which I had mentioned. There was a need to restart the HOST
before successfully adding it to the management server. Attaching the logs too.

You may need to do that, if you'd previously had any of the old builds installed. But, do
you need to do that even if you're starting with a fresh rhel server for management server
and the host is a freshly installed KVM host?

Regards.




Thanks and regards,

Checklist:
- Latest build #160 or above from http://jenkins.cloudstack.org/job/build-4.0-rhel63/
- Manually install jsvc package
- On mgmt server, check selinux policy
- Reinstall database, drop old databases and grant privileges (optiional)
- Agent is installed
- virt daemon is restarted and is running
- kvm modules are loaded as Wido suggests

I tested with 159, basic zone. Works for me.

Hi,

While adding a KVM host (Rhel 6.3) to the management server we are getting this error and

But when we restart the host and add again then the host gets added and we don't see any such
error. We have seen this consistently with last few ASF builds.
Is this an expected behavior??
