Kernel version 3.9.4-1 (linux-image-3.9-1-686-pae) made things worse.
The virtual machine tries to boot the kernel, but stops after a few
seconds and the kern.log shows:
kernel: [13851.000412] kvm [7482]: vcpu0 disabled perfctr wrmsr: 0xc1
data 0xffff
virtual machine was started with:
qemu-system-i386 -machine accel=kvm -m 512 -cdrom grml32-full_2013.02.iso
qemu-system-x86: 1.5.0+dfsg-3
