FYI. so far just reproduce the bug on E7450, 96 cpu host. test on another intel host, E5520 16 cpu. PASS on -smp 8/16. processor : 15 vendor_id : GenuineIntel cpu family : 6 model : 26 model name : Intel(R) Xeon(R) CPU E5520 @ 2.27GHz stepping : 5 cpu MHz : 2261.061 cache size : 8192 KB physical id : 0 siblings : 8 core id : 3 cpu cores : 4 apicid : 7 fpu : yes fpu_exception : yes cpuid level : 11 wp : yes 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 syscall nx rdtscp lm constant_tsc ida nonstop_tsc pni monitor ds_cpl vmx est tm2 ssse3 cx16 xtpr sse4_1 sse4_2 popcnt lahf_lm bogomips : 4522.04 clflush size : 64 cache_alignment : 64 address sizes : 40 bits physical, 48 bits virtual power management: [8]
I also can reproduce this problem when using rhevm(sm71) to install a vm(8 (8 sockets,1 core per socket) or 8 (2 sockets,4 cores per socket) on 96 cpu host (rhev-hypervisor-5.5-2.2.4).
Is it a regression? If so, since which version?
lihuang, Can you please arrange access to this machine (or similar Intel Xeon with >= 8 CPUs) and RHEV 5.5-2.2 (3). There is not enough information to clarify the issue.
Could it be a pvlcock issue, since clock=acpi_pm does work

I guess you need a host which could reproduce the bug, but now we only reproduce it on the E7450 (96 cpu host), and the machine is unavailable until this Thu... will update BZ when it is ready.
(In reply to comment #10) > Is it a regression? If so, since which version? will test previous version when the machine is available.
What about 16 CPU host?? After Thu, its ald RC.
already test on the 16 cpu host. result is PASS. 599034#c8
If this is in fact something that is proven to happen only with kvmclock, would be good to test with the new set of patches, that just got commited to RHEL5, and make sure they work. I just checked, and kernel-2.6.18-202.el5 has all the patches you need.

Can you close it?
