[pdm-devel] [PATCH proxmox-yew-comp 1/1] pve: qemu: handle fallback enum variants

[Stefan Hanreich]

pve-api-types introduced a fallback variant for all enums returned by
the Proxmox VE API. Add code for handling those new variants to the
use sites of those enums.

For AMD SEV and BIOS it is sufficient to print the unknown values,
since the Comboboxes prevent the re-submission of unknown values
anyway, due to the force_selection property being set to true.

For the OS type, we cannot uniquely identify if an OS is Windows or
not, since it is possible for an unknown value to be either Windows or
something else. For that case, the respective input field (machine
type), that needs this information to render content, is simply
disabled.
