I'm trying to change the default domain, the "internal" with the following command: engine-manage-domains -action=edit -domain=internal However, i am getting the following message: "Domain internal doesn't exist int the configuration" This is my domain admin user that is configured in the installation ovirt-setup. So, how can i fix it to include a user in this domain?

[Users] Why VDSM daemon resets SATA link too often
by Adam Tkáč 02 Nov '12

Hello all, I'm experiencing strange issue on one of the nodes. There is only one VM on the node but it generates _a lot_ of disk I/O. Sometimes vdsm writes following error to the system log: Nov 1 14:45:17 virtualizer respawn: slave '/usr/share/vdsm/vdsm' died, respawning slave Nov 1 14:45:20 virtualizer vdsm vds ERROR Unable to load the rest server module.

After that VM becomes unresponsible and I have to kill qemu-kvm process manually. The VM's image is stored on XFS system and after SATA reset it takes some time before XFS responds. During this time libvirtd daemon is not responsible and vdsm timeouts. Is it possible to configure vdsm not to reset SATA link every time when it starts? And if not, is it possible to increase timeout how long vdsm waits for libvirtd response? Thank you in advance. Regards, Adam

[Users] Installing ovirt-nightly problems
by Joop 02 Nov '12

02 Nov '12

Since I had some problems getting bonding working correctly in my ovirt-3.1 test installation I decide to start all over with a clean install and try the nightly, the webcast about bonding is using a nightly. That didn't go to well :-( What I did: - install Fedora-17 from live CD - yum upgrade --exclude=kernel* (stayed on 3.3.4-5) - yum localinstall http://ovirt.org/releases/ovirt-release-fedora.noarch.rpm - enabled nightly in ovirt.repo - yum install ovirt-engine Ended up with the following nightly rpms: ovirt-engine-3.1.0-3.20121031.gitdd0ad7f.fc17.noarch ovirt-engine-backend-3.1.0-3.20121031.gitdd0ad7f.fc17.noarch ovirt-engine-cli-3.2.0.5-1.20121025.git4189352.fc17.noarch ovirt-engine-config-3.1.0-3.20121031.gitdd0ad7f.fc17.noarch ovirt-engine-dbscripts-3.1.0-3.20121031.gitdd0ad7f.fc17.noarch ovirt-engine-genericapi-3.1.0-3.20121031.gitdd0ad7f.fc17.noarch ovirt-engine-notification-service-3.1.0-3.20121031.gitdd0ad7f.fc17.noarch ovirt-engine-restapi-3.1.0-3.20121031.gitdd0ad7f.fc17.noarch ovirt-engine-sdk-3.2.0.2-1.20121022.git8013c12.fc17.noarch ovirt-engine-setup-3.1.0-3.20121031.gitdd0ad7f.fc17.noarch ovirt-engine-tools-common-3.1.0-3.20121031.gitdd0ad7f.fc17.noarch ovirt-engine-userportal-3.1.0-3.20121031.gitdd0ad7f.fc17.noarch ovirt-engine-webadmin-portal-3.1.0-3.20121031.gitdd0ad7f.fc17.noarch ovirt-image-uploader-3.1.0-1.fc17.noarch ovirt-iso-uploader-3.1.0-1.fc17.noarch ovirt-log-collector-3.1.0-1.fc17.noarch ovirt-release-fedora-4-2.noarch ran engine-setup and gave default answers where possible. Instalation stopped with a Creating Database... ERROR Attached are the logs and the real error is in the enginedb log: user name is: engine Creating uuid-ossp extension... psql:/tmp/tmp.8hb5EYqc0Y:1: ERROR: permission denied to create extension "uuid-ossp" HINT: Must be superuser to create this extension. It is right, user engine isn't a superuser and thus not allowed to create the extension. I modified the CREATE ROLE statement to include SUPERUSER role and restarted engine-setup, now it continues and runs til the end. Looking at the code I think that the second invocation of creating the uuid-ossp extension isn't needed but commenting that line gives an error too. Looking at ovirt-stable and comparing the scripts in /usr/share/ovirt-engine does show some changes but I don't know enough internals to see what changed that causes this.

[Users] Ovirt-nightly and gluster
by jvandewege 02 Nov '12

02 Nov '12

I have an question regarding ovirt-nightly and the use of gluster. If I modify the CREATE ROLE to add SUPERUSER I can install ovirt-nightly and if I add my two storage hosts I can create a bond and add an ip address and it will be displayed in the webui. Further the static ip assignment of the ovirtmgmt interface doesn't fallback to DHCP like in ovirt-stable. Sofar OK. Now I want to use gluster for my two storage hosts. Can I do that with the versions of vdsm that are pushed to the hosts by ovirt? (All machines are basic Fedora 17 installs, upto date except for the kernel which is 3.3.4-5) and gluster-3.3.1-2 from baseurl=http://repos.fedorapeople.org/repos/kkeithle/glusterfs/fedora-$rele… Or do I need more recent versions of vdsm/libvirt/qemu? Thanks in advance, Joop
