I did none additional tests and the new CentOS 6.4 host failed start or migrate any vm.

I could find BZ#876958 which has the very same error. So I tried to apply patch http://gerrit.ovirt.org/9317. I had to apply it manually (guess patch would need a rebase for 3.1), but it works.

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.

Hi Dan, virsh -r cpu-compare <(echo '<cpu match="minimum"><model>Nehalem</model><vendor>Intel</vendor></cpu>') Host CPU is a superset of CPU described in /dev/fd/63 So libvirt obviously is fine.

6.4 CR: oVirt 3.1 breaks with missing cpu features after update to CentOS 6.4 (6.3 + CR)
by Patrick Hurrelmann 05 Mar '13

Hi list, I tested the upcoming CentOS 6.4 release with my lab installation of oVirt 3.1 and it fails to play well. Background: freshly installed CentOS 6.3 host in a Nehalem CPU-type Cluster with 2 other hosts. Storage is iSCSI. Datacenter and Cluster are both version 3.1. oVirt 3.1 was installed via Dreyou's repo. In CentOS 6.3 all is fine and the following rpms are installed: libvirt.x86_64 0.9.10-21.el6_3.8 libvirt-client.x86_64 0.9.10-21.el6_3.8 libvirt-lock-sanlock.x86_64 0.9.10-21.el6_3.8 libvirt-python.x86_64 0.9.10-21.el6_3.8 vdsm.x86_64 4.10.0-0.46.15.el6 vdsm-cli.noarch 4.10.0-0.46.15.el6 vdsm-python.x86_64 4.10.0-0.46.15.el6 vdsm-xmlrpc.noarch 4.10.0-0.46.15.el6 qemu-kvm.x86_64 2:0.12.1.2-2.295.el6_3.10 uname -a Linux vh-test1.mydomain.com 2.6.32-279.22.1.el6.x86_64 #1 SMP Wed Feb 6 03:10:46 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux virsh cpu capabilities on 6.3: <cpu> <arch>x86_64</arch> <model>Nehalem</model> <vendor>Intel</vendor> <topology sockets='1' cores='4' threads='1'/> <feature name='rdtscp'/> <feature name='pdcm'/> <feature name='xtpr'/> <feature name='tm2'/> <feature name='est'/> <feature name='smx'/> <feature name='vmx'/> <feature name='ds_cpl'/> <feature name='monitor'/> <feature name='dtes64'/> <feature name='pbe'/> <feature name='tm'/> <feature name='ht'/> <feature name='ss'/> <feature name='acpi'/> <feature name='ds'/> <feature name='vme'/> </cpu> and corresponding cpu features from vdsClient: cpuCores = 4 cpuFlags = fpu,vme,de,pse,tsc,msr,pae,mce,cx8,apic,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_Conroe,model_Penryn, model_Nehalem cpuModel = Intel(R) Xeon(R) CPU X3430 @ 2.40GHz cpuSockets = 1 cpuSpeed = 2394.132 So the system was updated to 6.4 using the continuous release repo.

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.

CetOS-6.4 via 6.3/cr
by Karanbir Singh 01 Mar '13

01 Mar '13

hi, By now most people would have seen or atleast have spotted the 6.3/cr/ repos are populated and updates there announced to the cr-announce list. 6.4 is a big release, lots of changes and lots of feedback about things ( also, we found in our limited testing that there are some surprises around the corners! ) Most people on the -devel list here should know about how we use the /cr/ repo and its implications - So with that in mind, please test the package payloads and provide feedback on this list. We are going to start working on the isos from today/tomorrow and start testing those right away, but in the mean time it would be great if we could get as wide as possible testing done against 6.3 + cr, and then document into the Release Notes whatever comes through. And remember, even if the test passes - let us know what you tested and that it passes'. Its important for us to build a coverage model as well.

Hi. Someone posted a Google+'s CentOS page link (https://plus.google.com/105218000125199596028) in CentOS Facebook group, so I was wandering if it is official group, and if we have CentOS group (Community) on G+? I found https://plus.google.com/communities/110237188526999056491 admined by "Brian Schueler". -- Ljubomir Ljubojevic (Love is in the Air) PL Computers Serbia, Europe StarOS, Mikrotik and CentOS/RHEL/Linux consultant

rpm and ls.do issues
by Oleg Tsarev 25 Feb '13

25 Feb '13

Hi everybody, I am sorry if my question simple and well-known. After several hours investigating man-pages, google and books I did not found answer to my question. Short version of question: Does rpm update ld.so config files after/during install rpm package with so-files? Longer version of question. Our software (to some reasons) uses boost 1.46.1 under CentOS 6.3. We can not downgrade to lower version of boost to some reasons, most important - we support also Ubuntu 12.04 LTS, and really do not want develop/test/support two version of product with different boost versions. We built related boost packages, put their to our repository, and everything works fine. Unfortunately, one customer use boost 1.41 version in some internal software from official CentOS repository, and customer can not use together our software and his internal software. We decided rename our "boost" packages to "product_name-boost-*" and move library files from /usr/lib64 to /opt/product_name/version/lib (path /opt/product_name/version we use for our internal software). I rebuilt boost packages, everything works fine. The question which I try to understand: do we need update LD_LIBRARY_PATH for our binaries? As far I can see, ldd show correct pathes to boost. I do not understand well, how exactly works rpm in this moment, and what the best solution: 1) find way to have together boost 1.41 and 1.46.1 without package renames (which problem we can meet? how "yum remove boost*" would works? how to remove specific version of boost? etc) 2) rename packages from "boost* to "product_name-boost-*" and do not change path from /usr/lib64 3) rename packages from "boost*" to "product_name-boost-*" and change install pathes for libraries/include to /opt/product_name/version/... 4) (3) + setup LD_LIBRARY_PATH for every our binary I hope to your advices, links, help. Thank you very much, Oleg
