kvm-75 worked well. Now both 76 and 77 fail to boot. 76 gave no
hint and a Google check showed it to be blamed on CONFIG_KVM_GUEST
option in the linux kernel .config.
Host is Fedora 8 with kernel-2.6.26.5-28.fc8.x86_64
Guest is Fedora 9 with kernel-2.6.26.5-45.fc9.i686
Hardware is Asus P5B Deluxe, Core 2 E6600 with
flags: fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov
pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe
syscall nx lm constant_tsc arch_perfmon pebs bts rep_good pni
monitor ds_cpl vmx est tm2 ssse3 cx16 xtpr lahf_lm
Trying to boot with kvm-77 gave a debugging hint, so here is
what I get. Does not look informative to me though. This was
typed from screen (Can copy paste work?):
Startup script:
modprobe kvm-intel; sleep 1

Hope this helps.
