Hi guys, Shew! Been a busy oVirt week for me :) I'm trying to add a 3rd host into my datacentre but each time the install is failing. In the front end I'm seeing "could not resolve host verify computer/domain name".

So this explains why I'm having the issue then, node02.blabla.com(10.0.2.22) is my old engine, my new engine hostname is backup.blabla.com(10.0.2.23)... any idea how I change this?

Thank you! Neil Wilson.

When running engine-config I see that there are two options that still refer to my old engine, I presume both should be changed? engine-config -a | grep -i node VdcBootStrapUrl: http://node02.blabla.com:80/Components/vds/ version: general VirtualMachineDomainName: node02.blabla.com version: general Also I've tried setting my VdcBootStrapUrl, but I'm battling to get the syntax correct, I've tried all sorts of combinations, but none seem to work, not sure if the key should be quoted, or declared completely or if just the key should be specified etc? [root@backup ~]# engine-config -g VdcBootStrapUrl VdcBootStrapUrl: http://node02.blabla.com:80/Components/vds/ version: general [root@backup ~]# engine-config -s key=VdcBootStrapUrl backup.blabla.com --cver=http://node02.blabla.com Error setting key's value. No such entry with version http://node02.blabla.com.

I've tried specifying the full path, tried quoting and all sorts of different variants of the above combinations without any success. Please could you perhaps give me an example of the correct usage? Thank you. Regards. Neil Wilson.

I've tried to browse to the url you gave me on your first reply both from the new host and one of the existing ones and I receive the following... JBoss Web/7.0.13.Final - Error report HTTP Status 404 - /Components/vds/ type Status report message /Components/vds/ description The requested resource (/Components/vds/) is not available. JBoss Web/7.0.13.Final Seems like something still isn't correct after the upgrade/migration to the new machine... any ideas what to try next? Thanks!
