Tested in kvm-83-164.el5_5.2, this problem does not exist when disabled npt. cmd: /usr/libexec/qemu-kvm -no-hpet -rtc-td-hack -usbdevice tablet -smp 2 -m 4G -drive file=f12_32.qcow2,if=ide -net nic,vlan=0,macaddr=20:88:99:11:99:11 -net tap,vlan=0,script=/etc/qemu-ifup -uuid `uuidgen` -cpu qemu64,+sse2 -vnc :16 -monitor stdio -boot n result: f12_32bit guest can be installed successfully and then can boot successfully.
On my system this for some reason only affects F13 guests, not F11/F12 ones. Marcelo Tosatti <mtosatti> provided a temporary fix that did not require any modification of the host kernel, if I get his permission I will attach the fix to this bug.
(In reply to comment #7) > On my system this for some reason only affects F13 guests, not F11/F12 ones. I can reproduce this with f12_32bit guest in my local host using kvm-83-164.el5_5.1.
