I have my desktop running Rawhide. On my last few boots - I think since the move to kernel 3.11 - the kvm-intel module is not loaded on boot; I have to manually load it (and restart libvirtd.service, but I think that's a libvirtd bug...) before I can run any VMs. [adamw@adam ~]$ modinfo kvm-intel filename: /lib/modules/3.11.0-0.rc0.git3.1.fc20.x86_64/kernel/arch/x86/kvm/kvm-intel.ko license: GPL author: Qumranet alias: x86cpu:vendor:*:family:*:model:*:feature:*0085* depends: kvm intree: Y vermagic: 3.11.0-0.rc0.git3.1.fc20.x86_64 SMP mod_unload signer: Fedora kernel signing key sig_key: 39:6B:81:E1:5F:3E:FC:8E:1C:65:1F:67:7A:42:D1:F1:FA:FE:D1:5B sig_hashalgo: sha256 parm: vpid:bool parm: flexpriority:bool parm: ept:bool parm: unrestricted_guest:bool parm: eptad:bool parm: emulate_invalid_guest_state:bool parm: vmm_exclusive:bool parm: fasteoi:bool parm: enable_apicv:bool parm: enable_shadow_vmcs:bool parm: nested:bool parm: ple_gap:int parm: ple_window:int [adamw@adam ~]$ cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 42 model name : Intel(R) Core(TM) i7-2600K CPU @ 3.40GHz stepping : 7 microcode : 0x17 cpu MHz : 3706.000 cache size : 8192 KB physical id : 0 siblings : 8 core id : 0 cpu cores : 4 apicid : 0 initial apicid : 0 fpu : yes fpu_exception : yes cpuid level : 13 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 pbe syscall nx rdtscp lm constant_tsc arch_perfmon pebs bts rep_good nopl xtopology nonstop_tsc aperfmperf eagerfpu pni pclmulqdq dtes64 monitor ds_cpl vmx est tm2 ssse3 cx16 xtpr pdcm pcid sse4_1 sse4_2 popcnt tsc_deadline_timer aes xsave avx lahf_lm ida arat epb xsaveopt pln pts dtherm tpr_shadow vnmi flexpriority ept vpid bogomips : 7004.76 clflush size : 64 cache_alignment : 64 address sizes : 36 bits physical, 48 bits virtual power management: (there's 8 identical outputs, as it's a quad core HT CPU).

<dgilmore> adamw: udev should load it <nirik> adamw: in the past qemu loaded those modules, but systemd/udev folks said "no need, it should get loaded by udev" so they dropped loading it... so it sounds to me like udev isn't doing what is expected?
*** Bug 991716 has been marked as a duplicate of this bug. ***
This seems to be OK in recent kernels - pretty sure it was fixed at least by rc3, it's definitely fixed in rc4.
Perhaps the fix is in systemd [.f20] - as I has this issue on f19 with rc4 kernel-3.11.0-0.rc4.git0.2.fc20.x86_64 systemd-204-9.fc19.x86_64 I can workarround it though...
