I installed the 64 bit RC6 rawhide using the rawhide anaconda. This is the first time I used Fedora 21 Anaconda instead of a Heisenbug anaconda.
I could not get the Fedora 21 anaconda to use my local tree for the install. Selecting "closest mirror" worked but slowly - took 90 minutes to install. What is wrong with the "default" file??????

RC6 rawhide seems to run fine except for virbr0. Neither net manager nor I can grok it.
Phoronix test suite 5.0 gives frame rates about 8 times slower than on Heisenbug with Nvidia drivers.
