[Users] Adding oVirt Node Fails

Tue May 8 03:06:04 UTC 2012

Results of testing, round 3 (trying to get [Errno 16] Device or resource busy '/etc/pki/vdsm/certs/cacert.pem' error.)
Variable: no symlink to /etc/system-release

I started with a reinstall of ovirt-engine and ovirt-node-2.3.0 (formatted drive, reinstalled), enabled network (via logical network breth0 through device eth0), and set the Ovirt Engine Admin Password on the node.Created a new host in ovirt-manager, host went to "Pending Approval".On the manager, clicked the host, clicked approve, and clicked ok (on power management warning)
And.... we passed the cert install!  And everything worked up until I hit the cpuFlags issue.
So... it wasn't the sym-link.  Borked install? I guess the only think I did different these times from before was I used a Fedora 16 disk to format the drive between each attempt, instead of using the ovirt-node disk and performing a reinstall, as well as rebuilding ovirt-manager.
Not sure where this leaves this topic. Seems I can properly add a node now without a cert or bridge renaming issue.- NickFrom: cybertimber2000 at hotmail.com

Results of testing, round 2 (trying to get [Errno 16] Device or resource busy '/etc/pki/vdsm/certs/cacert.pem' error.)

Again, I started with a reinstall of ovirt-engine and ovirt-node-2.3.0 (formatted drive with F16 disk, reinstalled), enabled network (logical = breth0, device = eth0). 
This time, I set the management server (by IP address and default port), with the [*] Connect to oVirt Engine and Validate Certificate set, and entered the oVirt Engine Admin Password. 
Ovirt prompts to confirm fingerprint, accepted. (quickly a message about pki and "persisted" appears on screen).
Created a new host in ovirt-manager, host went to "Pending Approval".
On the node shell, performed "ln -s /etc/system-release /etc/rhev-hypervisor-release" ((note: not sure this make an effect yet, I think it's the validating certificate part, but did so that only ONE thing changed between first and second test.))
On the manager, clicked the host, clicked approve, and clicked ok (on power management warning)
Ended at missing cpuFlags.

So we are at the same point as before, which means my idea on what caused it (validate certificate) didn't cause it.  Now for testing without the sym-link that Doron suggested.

Ok so here is the results of testing:
I started with a reinstall of ovirt-engine and ovirt-node-2.3.0 (formatted drive, reinstalled), enabled network (via logical network breth0 through device eth0), and set the Ovirt Engine Admin Password on the node. Created a new host in ovirt-manager, host went to "Pending Approval".
On the node shell, performed "ln -s /etc/system-release /etc/rhev-hypervisor-release"
On the manager, clicked the host, clicked approve, and clicked ok (on power management warning)
Ended at missing cpuFlags.

SO: We are at the same point that I was at with the plain Fedora16 + VDSM install, which is good. No issue with failing to install the cert!  

But I think I know what has been causing the OSError: [Errno 16] Device or resource busy '/etc/pki/vdsm/certs/cacert.pem' error.
Working through that now, will post the step by step when I have it.
