It passes here, and fails with "-cpu host": PASS: CPUID consistency FAIL: Test on PCID when enabled PASS: Test on INVPCID when disabled Looks like the "Test on PCID when enabled" has problems, and the -cpu flag is a red herring. > - msr (HANG) > ./x86-run x86/msr.flat -smp 1 > > $ sudo ./x86-run x86/msr.flat -smp 1qemu-system-x86_64 -enable-kvm > -device pc-testdev -device isa-debug-exit,iobase=0xf4,iosize=0x4 > -display none -serial stdio -device pci-testdev -kernel x86/msr.flat -smp 1 > enabling apic > enabling apic > enabling apic > > "enabling apic" repeats and adding -cpu host seems to have no effect. > Interestingly enough on an Ubuntu 3.13 series kernel this PASSes. The APICBASE register is already tested by the apic testcase, and the simple-minded tests in msr.flat actually trigger a general protection fault nowadays because the quality of the emulation improved. I'm dropping the APICBASE tests from msr.flat. > - vmx (HANG) > Test suite: interrupt > PASS: direct interrupt while running guest > PASS: intercepted interrupt while running guest > PASS: direct interrupt + hlt > > Here it just hangs. It fails here for me. It could be related to APICv, can you try with the enable_apic=0 parameter to kvm-intel.ko?
