I'm trying to run Hiren's BootCD on QEMU but it throws a hardware error 0x80000021 on a Core 2 Duo, maybe there is some parameter missing to fix that.



$ kvm --version
QEMU emulator version 1.0 (qemu-kvm-1.0), Copyright (c) 2003-2008 Fabrice Bellard
$ uname -a
Linux tiago-pc 3.2.0-37-generic #58-Ubuntu SMP Thu Jan 24 15:28:10 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
$ lsb_release -r
Release: 12.04
$ cat /proc/cpuinfo
output file: http://pastebin.com/7afK8dZ6
$ kvm -m 512 -cdrom PATH_TO_THE_FILE/HBCD_15.2.iso -boot once=d
KVM: entry failed, hardware error 0x80000021


full output file



The boot list is shown, but doesn't matter which option I choose it always gives the same error, I've tried on qemu-system-i386 and qemu-system-x86_64 as well, resulting in the same problem.



I do upgrade and dist-upgrade every day, and I've just tried to run it on 12.10 livecd (of course, without upgrade), unless it was fixed after the release the problem still happens!



Some sites I found with this error says to add the parameter -cpu core2duo or -enable-kvm but it didn't solve the bug.

I was able to fix the problem disabling on BIOS the flag Vanderpool, it seems Core 2 Duo don't have a full virtualization support, since the error says "the guest maybe running in big real mode which is not supported on less recent Intel processors", QEMU runs well on a Core i5 I have at home, and on a Pentium 4 without VT support!



Well, I hope QEMU could workaround these kind of problem in the future, but for now the problem is fixed.
