I often use Rawhide in virt-manager using KVM. My host machine is Fedora 12. Recently I noticed that booting Rawhide takes ages. After more careful examination I found out that "Applying Intel CPU microcode update" line pauses the system exactly for 1 minute. Then the boot continues. I don't know if it is a problem in Rawhide or in some update of libvirt.
Anyone seen similar problem?

I've noticed this too. The `modprobe microcode` seems to take about a minute or so. This probably needs a bug report,

It's known on the devel list for days, your bug is probably a dupe ;)

It is, as mentioned in one of the comments. It's just not been marked as such yet.

Yes. There are at least two if not more upstream issues.
1) The microcode module is incorrectly (re) loading microcode onto hyperthreaded cpus (Intel only issue). This doubles the time required. 2) The udevd/firmware interface is really slow.
The most recent regression I believe is due to the fact that earlier in F12 the firmware.sh script invoked by udev was incorrect, so the firmware was actually not being loaded (that was quicker).
I had some brief discussions on lkml about all this and then turned off the service and moved the load into rc.local (nohup service microcode_ctl start &)
