We have checked three source versions 8767:0defafc42af4, 8781:dcc2beb8a1d2, 8793:974ed9f73641. The VMX/HVM (IA-32 UP mode) of changset 8767/8781 often can not be created if it was builded by gcc 3.4.2/Fedora Core 3 or gcc 4.0.1/FC4. But it works well if it was builded by gcc 3.4.3/RHEL4u1 or gcc 3.4.4/RHEL4u2. The VMX/HVM guest often hangs for many different error, serial port often show us : --------------------- XEN) (GUEST: 20) Boot from Hard Disk 0 failed (XEN) (GUEST: 20) FATAL: Not a bootable disk (XEN) (GUEST: 20) Unknown opcode at F000:09E1=0xF09E1 (XEN) (GUEST: 20) Halt called from %eip 0xD2B1A ----------------------- or ----------------------- (XEN) (GUEST: 13) rombios.c,v 1.138 2005/05/07 15:55:26 vruppert Exp $ (XEN) HVM_PIT: guest freq in cycles=189652690 (XEN) (GUEST: 13) Remapping master: ICW2 0x8 -> 0x20 (XEN) (GUEST: 13) Remapping slave: ICW2 0x70 -> 0x28 (XEN) (GUEST: 13) VGABios $Id: vgabios.c,v 1.61 2005/05/24 16:50:50 vruppert Ex$(XEN) (GUEST: 13) HVMAssist BIOS, 1 cpu, $Revision: 1.138 $ $Date: 2005/05/07 1$(XEN) (GUEST: 13) (XEN) (GUEST: 13) ata0-0: PCHS=723/16/63 translation=none LCHS=723/16/63 (XEN) (GUEST: 13) ata0 master: QEMU HARDDISK ATA-2 Hard-Disk (355 MBytes) (XEN) (GUEST: 13) ata0 slave: Unknown device (XEN) (GUEST: 13) Unknown opcode at F000:FFFF=0xFFFFF (XEN) (GUEST: 13) Halt called from %eip 0xD2B1A ------------------------ even it can be created successful. serial port also has lots of complian: ----------------------- (XEN) (GUEST: 14) Booting from Hard Disk...

So some code depends on the gcc version?
