[Users] 6.4 CR: oVirt 3.1 breaks with missing cpu features after update to CentOS 6.4 (6.3 + CR)
Hi list, I tested the upcoming CentOS 6.4 release with my lab installation of oVirt 3.1 and it fails to play well.

What is libvirt's opinion about your cpu compatibility? virsh -r cpu-compare <(echo '<cpu match="minimum"><model>Nehalem</model><vendor>Intel</vendor></cpu>') If you do not get "Host CPU is a superset of CPU described in bla", then the problem is within libvirt. Dan.

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. Something different would have surprised my as virsh capabilities seemed correct anyway.

virsh capabilities on 6.4: <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,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_coreduo,model_Conroe cpuModel = Intel(R) Xeon(R) CPU X3430 @ 2.40GHz cpuSockets = 1 cpuSpeed = 2394.098
Full outputs of virsh capabilities and vdsCaps are attached. 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?
Best regards Patrick

seems like a vdsm issue - can you check if you have this patch (not sure its related):
commit 558994f8ffe030acd1b851dfd074f3417681337b Author: Mark Wu <wudxw@linux.vnet.ibm.com> Date: Tue Oct 9 11:18:10 2012 +0800
Fix a bug in the naming convertion of cpu feature 'sse4_x'
The list slice opertion missed the last character. It caused the feature name couldn't get chance to be converted into libvirt's naming.

My version of vdsm as stated by Dreyou: v 4.10.0-0.46 (.15), builded from b59c8430b2a511bcea3bc1a954eee4ca1c0f4861 (branch ovirt-3.1)

I applied that patch locally and restarted vdsmd but this does not change anything. Supported cpu is still as low as Conroe instead of Nehalem. Or is there more to do than patching libvirtvm.py?
What is libvirt's opinion about your cpu compatibility?
virsh -r cpu-compare <(echo '<cpu match="minimum"><model>Nehalem</model><vendor>Intel</vendor></cpu>')
If you do not get "Host CPU is a superset of CPU described in bla", then the problem is within libvirt.
Dan.
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. Something different would have surprised my as virsh capabilities seemed correct anyway.
So maybe, just maybe, libvirt has changed their cpu_map, a map that ovirt-3.1 had a bug reading. Would you care to apply http://gerrit.ovirt.org/5035 to see if this is it? Dan.

Thank you for reporting this issue and verifying its fix. I'm not completely sure that we should keep maintaining the ovirt-3.1 branch upstream - but a build destined for el6.4 must have it.

Well, I suppose that qemu would allow migration if you begine with a a *guest* of version rhel6.3.0. Please try it out. Dan.

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. Something different would have surprised my as virsh capabilities seemed correct anyway.
So maybe, just maybe, libvirt has changed their cpu_map, a map that ovirt-3.1 had a bug reading.
Would you care to apply http://gerrit.ovirt.org/5035 to see if this is it?
Dan.
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.
Thanks again and best regards
Thank you for reporting this issue and verifying its fix.
I'm not completely sure that we should keep maintaining the ovirt-3.1 branch upstream - but a build destined for el6.4 must have it.
If you believe we should release a fix version for 3.1, please verify that http://gerrit.ovirt.org/12723 has no ill effects.
Dan.
I did none additional tests and the new CentOS 6.4 host failed start or migrate any vm. It always boils down to:

Alright, just verified it. A vm started on a 6.3 host can be successfully migrated to the new 6.4 host and then back to any other 6.3 host. It just won't migrate a vm started on 6.4 to any host running 6.3.

But I guess this is fine and migration from higher host version to a lower version is probably not supported, right?
Well, I suppose that qemu would allow migration if you begine with a a *guest* of version rhel6.3.0. Please try it out.
Dan.
Alright, just verified it. A vm started on a 6.3 host can be successfully migrated to the new 6.4 host and then back to any other 6.3 host. It just won't migrate a vm started on 6.4 to any host running 6.3.
This surprises me. Engine should have used the same emulatedMachine value, independent of the initial host. Could you share the vdsm.log lines mentionioning "emulatedMachine" in both cases? Dan.

Hi Dan, sorry for coming back this late. I checked it and the default emulatedMachine is pc.

Hi Dan,

the value sent to vdsm from the engine is configurable per cluster compatibility version, no reason for it to be 'pc' anywhere, you can use engine-config to change EmulatedMachine to the correct value (for 3.2 cluster probably you need to use 'rhel6.3.0')
