Re: [Users] Adding Host

Hi, so you mean ist saver and better to let bootstrap do its work instead of doing it manualy, right? Ok, but I have already kmv hosts I wanna add to ovirt. Whats the best way todo? Save the vms somewhere and reinstall the host via bootstrap and move the vms back via virt-v2v?

There are some conflicts that are not in RPM level, which bootstrap knows how to handle. These will not be handled in the path you're taking. Similar issues you should expect is bios virt flags and kernel / OS validations bootstrap is doing. Furthermore, bootstrap is auto-generating a vdsm configuration, as well as other things such as networking (which you stumbled upon), time-sync, key & certificate generation signed by the engine-core, along with setting up a core-dump folder and probably some other things which I forgot. So as you can understand bootstrap is handling many issues, and manual installation, although possible, will not b e a simple one. If you're heading this way I suggest you read the vdsm_bootstrap, vdsm_bootstrap_complete, deployUtil and vds_installer python scripts. All should be available on your engine-core machine.

Then I have a completely running kvm system with virtual machine manager and so on. What do I have to do to add this host to ovirt?

From this point of view, we concentrate on VDSM, while kvm is simply a kernel module which should be loaded. Anything beyond will probably cause manual intervention as you just had. > > > On 27/03/12 12:32, Rene Rosenberger wrote: >> Hi, >> >> I think I will give it a new try from the scratch. What is the procedure to add a centos 6.2 host where is already kvm running with vms? Lets forget the vms for a while and think only about that kvm is already installed on the host I want to add to ovirt. >> >> Regards, >> rene >> >> -----Ursprüngliche Nachricht----- >> Von: Doron Fediuck [mailto:dfediuck@redhat.com] >> Gesendet: Dienstag, 27.
