Trouble activating host on RHEV3.0
Here's the setup:
60day RHEV 3.0 evaluation.
RHEV Virtualization Manager running on a VM
RHEV Hypervisor running on a Dell laptop with virtualization enabled
Trouble: Adding the host to the Default cluster is not an issue. However, trying to "Activate" the host results in a "Host xxxx is non-responsive" error in the Events tab. Trouble is that I do not even know where to begin to check for issues.
Can someone here point me to where I can possibly start looking - logs etc - so I can get past this issue?
A bit of search took me to "vdsm" so I started looking... One thing I noticed in the vdsm log on the RHEV Hypervisor (if of any use) - /var/log/vdsm/vdsm.log - is :
MainThread::ERROR::2012-03-29 08:16:12,103::vdsm::74::vds::(run) Traceback (most recent call last):
File "/usr/share/vdsm//vdsm", line 72, in run

and trying to start vdsmd results in:
/etc/init.d/vdsmd start
vdsm: Missing certificates, vdsm not registered [FAILED]
Starting iscsid:
Starting up vdsm daemon:

Hi Sanjay,
Welcome to Red Hat User Groups!
If I remember correctly, you were going to check your DNS setting to make sure name resolution works fine in your environment. How did that go?
OK, lets try the following:
1. remove the host using the RHEV-M GUI
2. open the RHEV-H console
you should be able to see the configuration menu (over ssh, login as admin, not as root)
3. go to the RHEV-M part of the menu
4. Enter the RHEv-M's FQDN after "Managerment Server"
5. Enter 8443 as the management port
6. make sure "Connect to RHEV Manager and validate Certificate" is checked
7. Enter the admin@internal 's password twice
After this, the host should appear in RHEV-M GUI, with the status "awaiting approval". In the GUI, hit the "Approve" button, the host will get registered, reboot, and should come up after reboot as "Up".
hmm, ok, this means something went wrong. Can you try the procedure again, and provide the rhevm.log from the rhev-m machine as well as vdsm-reg.log from the host ?
I experienced the same issue when tried to add rhev6.2 to production environment. Unfortunately there was a time-critical issue to deploy a number of VMs and a decision has been made to extend alternative virtualization platform using these blades so I had no time to track this issue :(
A few things I had run into adding a RHEL host to RHEV, while using Fibre Channel
review the logs /var/log/vdsm/vdsm.log on the RHEL client, /var/log/ovirt-engine/engine.log on the RHEV manager host.
I had to disable friendly names for my Hitachi SAN storage and allow vdsm sudo (NOPASSWD) priviliges on the RHEL client.
Also - I ran into isssues if I had installed using a 6.3 image and updated the system prior to installing RHEV on that host.
So, my procedure is:
- to kickstart the RHEL host
- bootstrap the host to my kickstart/Satellite with FULLY_UPDATE_THIS_BOX=0
- updates sudoers and multipath.conf
- ADD RHEL host to RHEV
- update the RHEL host
