Fixed in upstream merge commit eda1df0345f5a1e337e30367124dcb0e802bdfde, will be in QEMU v4.0.
The fix supersedes the old way of configuring OVMF
-drive if=pflash,format=raw,unit=0,readonly,file=/usr/share/edk2/ovmf/OVMF_CODE.fd \
-drive if=pflash,format=raw,unit=1,file=copy-of-OVMF_VARS.fd
by
-blockdev node-name=pflash0,driver=file,read-only=on,filename=/usr/share/edk2/ovmf/OVMF_CODE.fd \
-blockdev node-name=pflash1,driver=file,filename=copy-of-OVMF_VARS.fd \
-machine pflash0=pflash0,pflash1=pflash1
Verified on qemu-kvm-4.0.0-0.module+el8.1.0+3169+3c501422.x86_64:
plash device works well with blockdev.
-blockdev node-name=pflash0,read-only=on,driver=file,filename=/usr/share/OVMF/OVMF_CODE.secboot.fd \
-blockdev node-name=pflash1,driver=file,filename=/home/kvm_autotest_root/images/rhel810-64-virtio-scsi.qcow2.fd \
-machine pflash0=pflash0,pflash1=pflash1 \

Thanks. *** Bug 1717155 has been marked as a duplicate of this bug. *** Hi Laszlo: It looks that the slow train does not support Property '.pflash0'. /usr/libexec/qemu-kvm -M q35 -cpu SandyBridge -enable-kvm -m 4G -smp 4 -nodefaults \ -global driver=cfi.pflash01,property=secure,value=on \ -machine pflash0=pflash0,pflash1=pflash1 \ -blockdev node-name=pflash0,read-only=on,driver=file,filename=/usr/share/edk2/ovmf/OVMF_CODE.secboot.fd \ -blockdev node-name=pflash1,read-only=off,driver=file,filename=/tmp/new-edk2-version/OVMF_VARS.fd \ ... ... qemu-kvm: Property '.pflash0' not found Version: qemu-kvm-2.12.0-81.module+el8.1.0+3619+dfe1ae01.x86_64 edk2-ovmf-20190308git89910a39dcfd-5.el8.noarch Thank you for your help. The slow train has not gotten this feature. If it is needed there, ask for it by cloning this BZ for product "Red Hat Enterprise Linux 8". (In reply to Markus Armbruster from comment #14) > The slow train has not gotten this feature. If it is needed there, ask for > it by cloning this BZ for product "Red Hat Enterprise Linux 8". It's not needed. We don't plan to support -blockdev in RHEL8 (slow train) until a potential rebase of major virt components (qemu, libvirt, etc).
