GP exception on vmxon
Hello, I tried to write a piece of code to start vmx.
This code is directly interacting with cpu instead of with virtual cpu
as in xen.
But every time I call vmxon, a GP exception happens.
Could anybody help me on this? The following is the context
1. After booting up to the program, I disable A20M.
2. allocate a 4kb-aligned vmxon region and calculate its physical
address.
3. setup

failed when boot the kernel image on the hard disk from syslinux on a floppy
After formatting a floppy to MSDOS format and using syslinux /dev/fd0,
I successfully installed ldlinux.sys to the root directory of the
floppy.
Then I created a syslinux.cfg under the root directtory of this floppy
to load the linux kernel in my first hard disk, 3rd partition, boot
folder. The file system
of this partition is ext3. The floppy has a FAT file system. This config
file is listed

RE: A question on vmx loader in xen - how and when rombiosis loaded into memory
Thank you.
I notice the system then jumps to F000:FFF0 to execute. But because VMX is turned on, switching to real-mode would incur problems?
I don’t find any clue to turn on the vm86 mode as Readme in the tools/firmware directory puts.

Hi,
SYSLINUX isn't designed to work that way.
It can boot kernel only from same filesystem from which it's loaded.
You need GRUB or GRUB4DOS for your task.
SYSLINUX can be used to chainload GRUB.

A question on vmx loader in xen - how and when rombios is loaded into memory
A "main" function is defined in
Xen-3.1.0-source/tools/firmware/hvmloader/hvmloader.c.
In this main function, rombios, vgabios and vmxassist are copied to
specified address,
with following commands
memcpy((void *)ROMBIOS_PHYSICAL_ADDRESS, rombios, rombios_sz);
...
memcpy((void *)ETHERBOOT_PHYSICAL_ADDRESS, etherboot,
sizeof(etherboot));
....
