Thanks, but I've pushed it yesterday and thus I can no longer add you to the commit messages. Sorry.
I've just tested this patchset on Fedora 30. (I too can reproduce the behaviour Cole saw - duplicate 'secboot' binaries.)
Build libvirt with this:
$> git describe v5.7.0-107-gb6e6d35f3f
Stop the system libvirt daemons:
$> systemctl stop libvirtd virtlockd virtlogd
Start the daemons built from Git:
$> sudo ./run src/virtlockd & $> sudo ./run src/virtlogd & $> sudo ./run src/libvirtd &
Make sure your EDK2/OVMF RPM has the 'secboot' binaries/VARS files:
$> rpm -q edk2-ovmf edk2-ovmf-20190501stable-3.fc30.noarch
$> rpm -ql edk2-ovmf | grep secboot /usr/share/OVMF/OVMF_CODE.secboot.fd /usr/share/OVMF/OVMF_VARS.secboot.fd /usr/share/edk2/ovmf/OVMF_CODE.secboot.fd /usr/share/edk2/ovmf/OVMF_VARS.secboot.fd
(The top two files are a symlink to the bottom two.)
Before invoking domCapabilities API, ensure the relevant firmware descriptor files for x86_64 have the secboot binary listed:
$> grep CODE.secboot /usr/share/qemu/firmware/40-edk2-ovmf-x64-sb-enrolled.json /usr/share/qemu/firmware/50-edk2-ovmf-x64-sb.json /usr/share/qemu/firmware/40-edk2-ovmf-x64-sb-enrolled.json: "filename": "/usr/share/edk2/ovmf/OVMF_CODE.secboot.fd", /usr/share/qemu/firmware/50-edk2-ovmf-x64-sb.json: "filename": "/usr/share/edk2/ovmf/OVMF_CODE.secboot.fd",
Yeah, I've posted a patch for that: https://www.redhat.com/archives/libvir-list/2019-September/msg00485.html The reason is that (I suspect) 40-edk2-ovmf-x64-sb-enrolled.json and 50-edk2-ovmf-x64-sb.json have the same _CODE but different _VARS. Therefore, in qemuFirmwareGetSupported() (which is called when constructing domcaps) we effectivelly see two different firmwares: https://libvirt.org/git/?p=libvirt.git;a=blob;f=src/qemu/qemu_firmware.c;h=f... Therefore, they are appended onto @fws list which is then passed to virQEMUCapsFillDomainLoaderCaps() in virQEMUCapsFillDomainOSCaps() which doesn't deduplicate them. But the same thing can happen even without FW descriptors: ./configure --with-loader-nvram="/dev/null:X:/dev/null:Y" (a very dumb config, but serves the point) which declares [{CODE = "/dev/null", NVRAM = "X"}, {CODE = "/dev/null", NVRAM "Y"}] pair. In both cases the FW image is the same and therefore it would be printed twice. To test this with latest git just revert e9d51a221c1871 because now libvirt picks FW descriptors and thus configure arg (or correspondinf qemu.conf knob) is ignrored. Michal
