Unfortunately, kvm-17 was less successful here. FC6 did not boot any 
longer after I upgraded from kvm-16 to kvm-17, so I was rather surprised 
when I read the above message.

This is the test system:
CPU: Intel(R) Core(TM)2 CPU 6600 @ 2.40GHz, Chipset: Intel 975X

The exact problem was that FC6 stopped booting before under kvm-16 it 
would display the line
IP route cache hash table entries: 4096 (order: 2, 16384 bytes)

I then reverted to kvm-16 and repeated all upgrade changes until the 
problem occurred. The culprit was found to be
