So, an upgrade path seems possible, but it is not easy to find.
If you have a bullseye VM booting with OVMF_CODE.fd on a SCSI disk,
you have to:
1) change OVMF_CODE.fd into OVMF_CODE_4M.secboot.fd (or to another variant) in
the XML
2) remove (rename?) the _VARS.fd file
3) manually boot the VM from the UEFI shell
4) re-install grub ("grub-install efi")
As a side note, only the VirtIO SCSI controler is supported by
OVMF_CODE_4M.*, not lsilogic (that is the default for the
hypervisor with virt-manager/libvirt).
But this is probably #1016359
