[pve-devel] [PATCH qemu-server v2] use non SMM ovmf code file for i440fx machines

Dominik Csapak d.csapak at proxmox.com
Mon Oct 11 14:10:24 CEST 2021


ovmf with SMM enabled will not boot on i440fx (hangs on graphics
initialization), so load the non SMM variant.

should be no issue regarding live-migration since it never worked with
this anyway.

adapts the test and adds one with q35

Signed-off-by: Dominik Csapak <d.csapak at proxmox.com>

changes from v1:
* encode 'no-smm' instead of machine type in the ovmf hash
* move the is_q35 checks out of the get_ovmf_files
