Edit SeaBIOS version string

[pinkpepper]

Hi all,
I tried to edit SMBios version setting via GUI method but when launching Windows 10 guest and inspect system information, it seems to not set it correctly.
How can I accomplish that thing?

Thank you

Hi,
Please provide us with the VM config and the output of cat /etc/pve/storage.cfg command.

Here it is

dir: local
        path /var/lib/vz
        content vztmpl,backup,iso

lvmthin: local-lvm
        thinpool data
        vgname pve
        content images,rootdir

lvmthin: vm
        thinpool vm
        vgname vm
        content rootdir,images
        nodes pve-homelab

you can edit the SMBIOS settings in the UI under the VM's Options tab. Note that for Windows, you might need to fix the machine version (Edit Machine in the VM's Hardware tab) to 8.0 or lower, because newer QEMU defaults to SMBIOS v3 tables and Windows doesn't parse them. Alternatively to fixing the machine version, using OMVF/UEFI should work.

it doesn't work, it doesn't change the string rel-x.xx...prebuild.qemu.org

SMBIOS v3

are you sure that smbios == seabios
?

in my case, you only need to rebuild seabios from source

I never claimed that. But SMBIOS tables are used by both SeaBIOS and OVMF/UEFI. But you are right, the SMBIOS table exposed in the UI only changes (in the result of dmidecode) the System Information, not the BIOS Information.

To change the BIOS Information, you'd need to change the type=0 table. This can be done via custom args, e.g.
qm set 131 --args "-smbios type=0,version=123"

Yes, it works. thanks
