Description Adam Williamson 2013-07-12 18:51:31 EDT
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.

(there's 8 identical outputs, as it's a quad core HT CPU).

Not sure what other info you might need.

<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?

Comment 3 Adam Williamson 2013-08-07 14:58:43 EDT
This seems to be OK in recent kernels - pretty sure it was fixed at least by rc3, it's definitely fixed in rc4.
Comment 4 Satish Balay 2013-08-07 15:03:36 EDT
Perhaps the fix is in systemd [.f20] - as I has this issue on f19 with rc4


I can workarround it though...
