localdomain
by Koen Vanoppen 13 Jun '14

13 Jun '14

Hi Guys, It's bin a while :-). Luckily :-). I have a quick question. Is there a way to change the default .localdomain for the FQDN in ovirt? I would be handy if we just had to fill in the hostname of our vm (we are using 3.4, with the cloud-init feature) and he automatically adds our domain in stead of .localdomain. Kind regards, Koen

novnc error
by Garrett Baltezegar 13 Jun '14

13 Jun '14

Hello everyone, I'm running into an error getting novnc up and running with ovirt, and I'm hoping someone can help. My system is a CentOS minimal x86_64 install running ovirt fine. I have created VMs and I'm able to configure the console options. When I attempt to connect to them, however, I get a Server disconnected (code: 1006) error. I've searched online for a solution, but everything seems to point to simply running the engine-setup configuration utility and installing the ca.crt. I have tried both of these things, but I keep getting the same message, in Internet Explorer, Chrome and Firefox. Disabled iptables and selinux. Connected directly to VM with VNC Checked ovirt-websocket-proxy, and it is running - haven't touched config file - SSL=true Installed ca.crt - multiple times Reinstalled ovirt - clean first, the reinstall. Reinstalled ca.crt Nothing has helped so far. Does anyone have any ideas? I have a straight-forward setup using engine-setup; accepting the default answer most of the time. GlusterFS being one of the non-defaults. I appreciate your suggestions! GB

python-sdk: attach disk snapshot to another virtual machine
by Michael Ablassmeier 13 Jun '14

13 Jun '14

hi guys, according to an commit in Oct. 2013 there was a patch added to the SDK which allows to attach an existing snapshot to a virtual machine: commit 72e67dd5406f3c193234697ce88d92dbe64759d7 Author: Michael pasternak <mpastern(a)redhat.com> Date: Wed Oct 30 11:24:19 2013 +0200 sdk: regenerate against the latest api [..] - added ability to attach a disk snapshot to the virtual machine [..] I think this may be related to the new backup API: http://www.ovirt.org/Features/Backup-Restore_API_Integration can anyone give me an pointer on how to this through the python-sdk? Or is there an example for this anywhere to be found? Thanks! bye, - michael

KSM and cross-vm attack
