Hi I'm running a kvm-84 host with 2.6.28.7. Guests are two lenny and one Centos52 running a oracle db for test purpose. The host is a C2D E8400 @ 3.00GHz, 4G. HostOS debian lenny x86_64. I've lenny guests on on other hosts where I do not get this errors. I assume it is the centos guest which cause the output like this: [ 277.352002] br0: topology change detected, propagating [ 277.352004] br0: port 9(tap3) entering forwarding state [ 544.336354] kvm: 2130: cpu0 unhandled wrmsr: 0xc0010117 data 0 [ 560.347632] kvm: emulating exchange as write [ 864.493086] kvm: 2175: cpu0 unhandled wrmsr: 0xc0010117 data 0 [ 868.595641] kvm: 2180: cpu0 unhandled wrmsr: 0xc0010117 data 0 [ 1376.695123] kvm: 2231: cpu0 unhandled wrmsr: 0xc0010117 data 0 [ 1837.129301] kvm: 2231: cpu0 unhandled wrmsr: 0xc0010117 data 0 [ 2137.066450] kvm: 2231: cpu0 unhandled wrmsr: 0xc0010117 data 0 [ 2138.887426] emulation failed (mmio) rip 1c21 63 ed 58 75 [ 2138.887453] emulation failed (mmio) rip 1c21 63 ed 58 75 [ 2138.887477] emulation failed (mmio) rip 1c21 63 ed 58 75 [ 2138.887501] emulation failed (mmio) rip 1c21 63 ed 58 75 [ 2138.887525] emulation failed (mmio) rip 1c21 63 ed 58 75 [ 2138.887549] emulation failed (mmio) rip 1c21 63 ed 58 75 [ 2138.887573] emulation failed (mmio) rip 1c21 63 ed 58 75 [ 2138.887597] emulation failed (mmio) rip 1c21 63 ed 58 75 [ 2138.887621] emulation failed (mmio) rip 1c21 63 ed 58 75 [ 2201.858240] __ratelimit: 13683 callbacks suppressed [ 2201.858242] kvm: 2265: cpu0 unhandled wrmsr: 0xc0010117 data 0 [ 6586.374984] vcpu not ready for apic_round_robin [ 6586.376625] kvm: 2265: cpu0 unhandled wrmsr: 0xc0010117 data 0 [ 9171.274875] kvm: 2265: cpu0 unhandled wrmsr: 0xc0010117 data 0 [ 9817.268743] kvm: 2265: cpu0 unhandled wrmsr: 0xc0010117 data 0 [10019.314284] kvm: 2265: cpu0 unhandled wrmsr: 0xc0010117 data 0 [10021.239293] emulation failed (pagetable) rip 403 69 00 00 00 [10021.239320] emulation failed (pagetable) rip 403 69 00 00 00 [10021.239345] emulation failed (pagetable) rip 403 69 00 00 00 [10021.239369] emulation failed (pagetable) rip 403 69 00 00 00 [10021.239394] emulation failed (pagetable) rip 403 69 00 00 00 [10021.239419] emulation failed (pagetable) rip 403 69 00 00 00 [10021.239443] emulation failed (pagetable) rip 403 69 00 00 00 [10021.239468] emulation failed (pagetable) rip 403 69 00 00 00 [10021.239493] emulation failed (pagetable) rip 403 69 00 00 00 [10026.241002] __ratelimit: 3341322 callbacks suppressed [10026.241004] emulation failed (pagetable) rip 403 69 00 00 00 [10026.241030] emulation failed (pagetable) rip 403 69 00 00 00 [10026.241054] emulation failed (pagetable) rip 403 69 00 00 00 [10026.241079] emulation failed (pagetable) rip 403 69 00 00 00 [10026.241104] emulation failed (pagetable) rip 403 69 00 00 00 [10026.241128] emulation failed (pagetable) rip 403 69 00 00 00 [10026.241153] emulation failed (pagetable) rip 403 69 00 00 00 [10026.241178] emulation failed (pagetable) rip 403 69 00 00 00 [10026.241203] emulation failed (pagetable) rip 403 69 00 00 00 [10026.241227] emulation failed (pagetable) rip 403 69 00 00 00 [10031.245002] __ratelimit: 3338789 callbacks suppressed [10031.245004] emulation failed (pagetable) rip 403 69 00 00 00 [10031.245029] emulation failed (pagetable) rip 403 69 00 00 00 [10031.245054] emulation failed (pagetable) rip 403 69 00 00 00 [10031.245078] emulation failed (pagetable) rip 403 69 00 00 00 [10031.245103] emulation failed (pagetable) rip 403 69 00 00 00 [10031.245128] emulation failed (pagetable) rip 403 69 00 00 00 [10031.245153] emulation failed (pagetable) rip 403 69 00 00 00 [10031.245177] emulation failed (pagetable) rip 403 69 00 00 00 [10031.245202] emulation failed (pagetable) rip 403 69 00 00 00 [10031.245227] emulation failed (pagetable) rip 403 69 00 00 00 [10036.249004] __ratelimit: 3341353 callbacks suppressed [10036.249006] emulation failed (pagetable) rip 403 69 00 00 00 [10036.249031] emulation failed (pagetable) rip 403 69 00 00 00 [10036.249056] emulation failed (pagetable) rip 403 69 00 00 00 [10036.249081] emulation failed (pagetable) rip 403 69 00 00 00 [10036.249105] emulation failed (pagetable) rip 403 69 00 00 00 [10036.249130] emulation failed (pagetable) rip 403 69 00 00 00 [10036.249155] emulation failed (pagetable) rip 403 69 00 00 00 [10036.249180] emulation failed (pagetable) rip 403 69 00 00 00 [10036.249204] emulation failed (pagetable) rip 403 69 00 00 00 [10036.249229] emulation failed (pagetable) rip 403 69 00 00 00 [10041.253004] __ratelimit: 3340817 callbacks suppressed [10041.253007] emulation failed (pagetable) rip 403 69 00 00 00 -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
