Re: [Users] Unable to add fresh oVirt host

27 Apr 2012

      Are some more digging. I have discovered the following.

If provision a vdsm node exactly the same way and add it to an old, working
ovirt of mine, it works. I've reprovisioned the new ovirt again, the same
exact way as before and hit the same problem. Here is what I found on the
node logs:

There is no output after this. vds_boostrap log is empty.

if I run the bootstrap command as specified in the log file, I get this as
the only failure:

After installing the package, I got this:

<BSTRAP component='SetNetworking' status='FAIL' message='addNetwork error
trying to add rhevm bridge'/>
<BSTRAP component='SetSSHAccess' status='FAIL' message='Failed to retrieve
server SSH key.'/>
<BSTRAP component='RHEV_INSTALL' status='FAIL'/>

Finally, I looked at the bootstrap log and found the details:

It seems that ovirt is not able to create the bridge. What could be off?;
could I have missed a configuration step or param somewhere?. Note, that I
used the following answers file to install ovirt:

[general]
OVERRIDE_IPTABLES=no
HTTP_PORT=8080
HTTPS_PORT=8443
MAC_RANGE=00:1A:4A:A8:7A:00-00:1A:4A:A8:7A:FF

I am attempting to add the first host to a newly setup oVirt. Here is the
