[Users] Ims shared disks and ovirt storage
by Gianluca Cecchi 09 Apr '13

09 Apr '13

Hello, I have the chance to work on Intel blades where I have option to confihure shared disks between them at enclosure level. Their controller is scsi. How could I configure as shared storage in ovirt? I presume neither Fc nor iscsi are possible. .. so what can i do in your opinion? Thanks in advance Gianluca

[Users] DNS for IPA in oVirt
by René Koch (ovido) 09 Apr '13

09 Apr '13

Hi list, I don't want to ask my question in the mail thread of Eduardo to avoid mixing topics. Can you give me more detailed information on how oVirt is using DNS internally and how IPA users can work in the following scenario: # engine-manage-domains -action=list Domain: ovido.at User name: admin(a)OVIDO.AT Manage Domains completed successfully # cat /etc/hosts | grep engine 10.0.100.195 ovirt-engine.lab.ovido.at # ip a 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 00:1a:4a:00:64:14 brd ff:ff:ff:ff:ff:ff inet 10.0.100.195/24 brd 10.0.100.255 scope global eth0 # host ovirt-engine.lab.ovido.at ovirt-engine.lab.ovido.at has address 10.0.100.24 # host 10.0.100.24 24.100.0.10.in-addr.arpa domain name pointer ovirt-engine.lab.ovido.at. So in my case I have correct DNS settings (forward and reverse), but my ovirt-engine host has a totally different IP address. I didn't test SSO with Kerberos in user portal (maybe this want work), but authentication with IPA user in user portal and admin portal is working fine even with these totally wrong DNS configuration. Regards, René

[Users] oVirt Presentations
by René Koch (ovido) 09 Apr '13

09 Apr '13

Hello list, I just want to inform you that I'll be talking about RHEV and oVirt on 2 (maybe 3) events in Austria and Germany in the next weeks (45min presentation slots). The first one is at the Open Source Data Center Conference in Nuremberg, Germany which takes place from April, 17th to April, 18th: http://www.netways.de/en/osdc/osdc2013/ Details on my presentation (presentation language is German): http://www.netways.de/index.php?id=3732&L=1 Main focus will be Red Hat Enterprise Virtualization, but will also talk about oVirt. The second event is at the Graz Linux Days in Austria on April, 20th: http://www.linuxtage.at/ (Sorry, there's no English version available) Details on my presentation (in German): http://glt13-programm.linuxtage.at/events/174.de.html As this event is a non-profit community event I'll be focusing on oVirt, but will also talk about differences to RHEV. Eventually I'll be talking about oVirt on the Linux Weeks in Vienna, Austria, too. This event is from May, 2nd to May, 4th: http://www.linuxwochen.at/ At the moment the call for papers is still running... If there's someone from Germany or Austria on this list and attends on one of these events please let me know :) Regards, René

[Users] SPM is always contending

After the node acting as spm was (accidentally) put into maintenance mode, the spm role is always contending. The original node doesnt take the role back either. About 10 instances were still running on the node when it was put into maintenance. I have ovirt 3.1.0-4 with a targetcli iscsi store. Here are the contents of the engine.log.

Re: [Users] SPM is always contending - resolved
by Andy Singleton 07 Apr '13

Problem resolved. The clue was obviously in the engine.log (FSCK error) but I couldn't see what was needing an fsck or why this would prevent the storage of every vm from being mounted. I still dont understand the whole of the ovirt storage mechanism. More information was in the node vdsm.log - It pointed here. /dev/mapper/9ed5a2fe--ae4c--433f--a15f--2c710ed5156f-master One fsck later problem resolved. Thanks Andy

[Users] Fwd: cannot assign network without IP address

It seems like an old bug. Since oVirt3.1 a lot of bugs were fixed in the edit nic dialog. Maybe consider using ovirt3.2?
