[Users] Planning oVirt Workshops

(N.B.: This message was copied to users(a)ovirt.org but I am not clear if my subscription was approved. If you happen to note that this message did not get to that list, let me know.) Hello everyone, I am a new(ish) hire at Red Hat working on Carl Trieloff's team. I will be attending tomorrow's oVirt IRC meeting to provide an update on upcoming oVirt workshops, but in the interim wanted to circulate a proposed agenda. Please note that we're planning one day workshops at LinuxCon Japan, North America and Europe, as well as a 2 day workshop at NetApp HQ in California (target date 8 and 9th August 2012). As we're discussing workshop agendas for the one day events, it would be good to have an idea of what we'd like to present given the additional day. Here is a *very* preliminary agenda: - intro & arch - engine, vdsm deep dives - storage roadmap/discussion - network roadmap/discussion Open Questions: 1) What other topics should be covered during the workshop? 2) Who would like to volunteer to be an instructor? Cheers, LH -- Leslie Hawthorn Community Action and Impact Open Source and Standards @ Red Hat identi.ca/lh twitter.com/lhawthorn

[Users] locale en_AU
by Jason Lawer 23 Apr '12

23 Apr '12

I just tried to run engine-setup and got the following error. [root@manager ~]# engine-setup Error: current locale (en_AU.UTF-8) is not supported. supported locales are: en_US.UTF-8,en_US.utf-8,en_US.utf8 Please check log file /var/log/ovirt-engine/engine-setup_2012_04_23_09_07_53.log for more information While I can easily change the locale settings on the box, I really think this is a bit of a crazy limitation as almost every other bit of software seems to assume en_AU = en_US as almost no software ends up creating an Australian localization for it. The character set is the same, the keyboards are the same, and I can't see any reason why en_AU (or say en_NZ) would cause a problem. The only differences I can think of are dates (DD/MM/YYYY vs MM/DD/YYYY) and the metric system. What would need to be the process to fix this? Is this just because no one has been willing to test or it is a policy? Jason

[Users] fedora qemu modern CPU recognition issues cause ovirt manged host to go non-operational
by Dead Horse 22 Apr '12

22 Apr '12

Seeing an issue wherein ovirt moves a managed host to non-operational state. This occurs with the currently released version of ovirt and the latest development builds. The ovirt host is loaded with Fedora core 16 and equipped with most current development version of the vdsm. *Editorial node* The latest vdsm to work on the FC16 host required building and adding newer versions of the sanlock, libvirt, lvm2 and device-mapper packages than what FC16 provides. Ultimately however none of the newer packages have any bearing on this failure mode. The failure mode is as follows. Upon successfully adding the host and setting the cluster CPU compatibility level oVirt will offline the host with the following message: --> Host ovirtnode moved to Non-Operational state as host does not meet the cluster's minimum CPU level. Missing CPU features : model_Nehalem Under the hood the actual cause of this failure is that qemu is not correctly able to identify the host CPU feature flags. This can be observed by doing: qemu-system-x86_64 -cpu Nehalem,check which fails with: warning: host cpuid 0000_0000 lacks requested flag 'fpu' [0x00000001] warning: host cpuid 0000_0000 lacks requested flag 'de' [0x00000004] and on and on... A simple check of "cat /proc/cpuinfo | grep flags" flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe syscall nx rdtscp lm constant_tsc arch_perfmon pebs bts rep_good nopl xtopology nonstop_tsc aperfmperf pni dtes64 monitor ds_cpl vmx est tm2 ssse3 cx16 xtpr pdcm dca sse4_1 sse4_2 popcnt lahf_lm ida dts tpr_shadow vnmi flexpriority ept vpid Thus the CPU is more than capable of everything being asked of it via the cpudef for "Nehalem" in /etc/qemu/target-x86_64.conf. This is only an issue on Fedora hosts. RHEL/CentOS/SL hosts work fine. This was recognized as an issue RHEL and fixed there but has not been fixed in Fedora. See: http://wiki.qemu.org/Features/CPUModels#Examples and this: https://bugzilla.redhat.com/show_bug.cgi?format=multiple&id=689665 and this related discussion in qemu-devel: http://www.mail-archive.com/qemu-devel@nongnu.org/msg101360.html Thus is appears that the changes were made to the RHEL qemu (eg: cpu type rhel6) AKA the change one needs to make to the ovirt engine database to have ovirt manage a EL based host. Fedora hosts--> psql -U postgres engine -c "update vdc_options set option_value='pc-0.14' where option_name='EmulatedMachine' and version='3.0';" EL hosts --> psql -U postgres engine -c "update vdc_options set option_value='rhel6.2.0' where option_name='EmulatedMachine' and version='3.0';" Thus at the moment any host loaded with Fedora and manged by oVirt utilizing a Sandy Bridge, Nehalem or Westmere processor will be dead in the water. -DHC

[Users] Host status non-responsding
by Rahul Upadhyaya 20 Apr '12

20 Apr '12

Hi, While performing some operations (vdsm restart and other operations to debug SSL settings on the host) , my host goes to "non-responding" state. Now it has happened for the third time. For the previous two times I did a engine-cleanup and did a engine-setup to resolve this issue. Is there some other way ... m guessing removing some host entry from database or something to recover faster. On a non-responding host I can't put it to maintenance mode because it says it has running Vms on it... also I cant remove it and add it again, so basically my host is in a state of limbo where I cant perform any operation on it. Is there any other way to recover from such condition other that preforming a engine cleanup and engine-setup again ? -- Regards, Rahul =======================================================
