Hi, As report in launchpad (https://bugs.launchpad.net/qemu/+bug/712416), kvm intel kernel module is not usable with via nano (with vmx instructions). Cpu: processor : 0 vendor_id : CentaurHauls cpu family : 6 model : 15 model name : VIA Nano processor U2250 (1.6GHz Capable) stepping : 3 cpu MHz : 800.000 cache size : 1024 KB fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 10 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat clflush acpi mmx fxsr sse sse2 ss tm syscall nx lm constant_tsc up rep_good pni monitor vmx est tm2 ssse3 cx16 xtpr rng rng_en ace ace_en ace2 phe phe_en lahf_lm bogomips : 3192.36 clflush size : 64 cache_alignment : 128 address sizes : 36 bits physical, 48 bits virtual power management: Kvm version: tested with 0.12.5 and last git 0.13.50 (git repo deleted after test, I can't do "git describe" for now). Kernel version: 2.6.38 (git kvm branch compiled on 02 03 2011) Arch: x86_64 but reproductible (tested) with i386 Guest os: all, crash as soon as i enter kvm command. The problem appears with -no-kvm-irqchip or -no-kvm-pit too. The problem doesn't appear with -no-kvm or if kvm_intel kernel module is unloaded. Description of the problem: the host crash without any log when launching kvm with kvm_intel kernel module loaded. Command: kvm -m 256 fs/ubuntu_vm_1.img Thanks ! -- 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
