[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.

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

      <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,

              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.

   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
