Testing Nightly and Status Board
by Karanbir Singh 14 Mar '13

14 Mar '13

hi, At the moment, we run tests on a nightly basis, only in kvm vm's and the results dont go very far. I'd like to propose we use the entire QA bladecenter and run the entire compliment of deploys and tests, then post them in a status board which has some history ( stashboard ? ) Going one step further, we should run the entire t_functional tests as well as start incorporating some of the, now stale, t_external tests. At the moment we do deploys over http and nfs, to local and remote storage, under Xen, KVM, bare-metal and some virtualbox and some vmware hypervisors, for i386 and x86_64. I had a brief chat with Fabian about this yesterday, and we both think its doable, in the short term. Anyone else have thoughts about this ? or want to propose reporting mechanisms that might be better in line with the intended result : to give people a single perspective on the state of things, as a confidence point. And also to allow people to easily add tests that are then run nightly, so they can address their own corner cases.

qemu-kvm upgrade path is broken
by Morten Stevens 10 Mar '13

10 Mar '13

Hi, There is an upgrade problem with the latest qemu-kvm package for CentOS-6.4: Upgrading from qemu-kvm-0.12.1.2-2.355.el6_4_4.1.x86_64.rpm to the latest qemu-kvm-0.12.1.2-2.355.el6_4.2.x86_64.rpm package is not possible with "yum update". The problem is: qemu-kvm-0.12.1.2-2.355.el6_4_4.1.x86_64.rpm This package contains el6_4_4.1 instead of el6_4.1. Best regards, Morten

It just won't migrate a vm started on 6.4 to any host running 6.3.

Hi Dan, success! Applying that patch made the cpu recognition work again. The cpu type in admin portal shows again as Nehalem. Output from getVdsCaps: cpuCores = 4 cpuFlags = 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,xtopology,nonstop_tsc, aperfmperf,pni,dtes64,monitor,ds_cpl,vmx,smx,est,tm2, ssse3,cx16,xtpr,pdcm,sse4_1,sse4_2,popcnt,lahf_lm,ida, dts,tpr_shadow,vnmi,flexpriority,ept,vpid,model_Nehalem, model_Conroe,model_coreduo,model_core2duo,model_Penryn, model_n270 cpuModel = Intel(R) Xeon(R) CPU X3430 @ 2.40GHz cpuSockets = 1 cpuSpeed = 2393.769 I compared libvirt's cpu_map.xml on both Centos 6.3 and CentOS 6.4 and indeed they do differ in large portions. So this patch should probably be merged to 3.1 branch? I will contact Dreyou and request that this patch will also be included in his builds. I guess otherwise there will be quite some fallout after people start picking CentOS 6.4 for oVirt 3.1.

The only difference I can see is that 6.4 exposes one additional cpu flags (sep) and this seems to break the cpu recognition of vdsm. Anyone has some hints on how to resolve or debug this further? What more information can I provide to help?

another 6.4 gotcha
by Joe Pruett 03 Mar '13

03 Mar '13

something changed in the kvm audio subsystem, so a virt that was suspended during shutdown wouldn't resume after reboot. the logs had complaints of: savevm: unsupported version 2 for 'hda-audio' v1 load of migration failed i poked around on the rh bz site and found a few hits, but they seemed to be related to older versions. i forced a clean boot of my vm and it was happy.
