Can not boot the OVMF

Can not boot the OVMF

Hi Attilio

I have updated to the upstream Xen and try to boot into OVMF bios. Instead
of fetching the OVMF code from the git mirror,  I just copy the OVMF bios
to ovmf directory.
I use the bios="ovmf" in the HVM config file. But, there is an error when I
create the domain.

root@gavin-laptop:~# xl create hvm_ubuntu.hvm
Parsing config file /root/hvm_ubuntu.hvm
WARNING: specifying "tsc_mode" as an integer is deprecated. Please use the
named parameter variant. e.g. tsc_mode="default"
failed to free memory for the domain

So, do you have any ideas about this problem? Thank you very much.

Best Regards,
Bei Guan

Really not, can you try to build the ovmf from the mirror please?

I just used your latest patch "[PATCH v4] Fetch the OVMF repository from
specific git mirror and enable it", and compiled the firmware
successfully. It's OK for me now.

I can get the right OVMF bios in tools/firmware/ovmf. I provide my
environment. It's Ubuntu 10.04 and X86_64 bit kernel.

However, I still cannot not boot into the OVMF bios. The error is the same
as the above.
Could anyone tell me how this error "failed to free memory for the domain"
came about?

Thanks.

Hi,

I trace the code and there seems to be something error in the
function libxl__domain_build_info_setdefault() in libxl_create.c.

int libxl__domain_build_info_setdefault(libxl__gc *gc,
                                        libxl_domain_build_info *b_info)
{
...

    if (b_info->type == LIBXL_DOMAIN_TYPE_HVM) {
        if (!b_info->u.hvm.bios)
            switch (b_info->device_model_version) {
            case 1: b_info->u.hvm.bios = LIBXL_BIOS_TYPE_ROMBIOS; break;
            case 2: b_info->u.hvm.bios = LIBXL_BIOS_TYPE_SEABIOS; break;
            default:return ERROR_INVAL;
            }

        /* Enforce BIOS<->Device Model version relationship */
        switch (b_info->device_model_version) {
        case 1:
            if (b_info->u.hvm.bios != LIBXL_BIOS_TYPE_ROMBIOS)
                return ERROR_INVAL;
            break;
        case 2:
            if (b_info->u.hvm.bios == LIBXL_BIOS_TYPE_ROMBIOS)
                return ERROR_INVAL;
            break;
        default:abort();
        }
    }

Note the red part of the code above. If we set the option bios="ovmf" in
HVM config file, the vale of b_info->u.hvm.bios is 3. And the
variable LIBXL_BIOS_TYPE_ROMBIOS is always 1. So, in the xl_cmdimpl.c, we
get the error "failed to free memory for the domain". Maybe this error will
also happen when we boot into the Seabios.

Please correct me if possible. Thank you very much.

OVMF and SeaBIOS are only going to be supported with upstream qemu and
ROMBIOS will only be supported with the traditional qemu tree.

Naughty of me to use the bare numbers there, I should have used the enum
names. Will send out a patch.

This sounds like bad error handling in xl to me.
