[libvirt] On the content of 'nvram' section in /etc/libvirt/qemu.conf
by Kashyap Chamarthy 17 Apr '19

17 Apr '19

I learnt from Dan Berrangé that the 'nvram' section in `/etc/libvirt/qemu.conf` will now go away in light of all the work done in QEMU ('firmware.json', et al) and libvirt (the firmware auto-selection). But for my own education, can anyone confirm that the current content of 'nvram' is out of date in terms of mapping of OVMF binaries to their corresponding variable store ("VARS") files? Let's see what I mean. On my Fedora 29 box, in `/etc/libvirt/qemu.conf`, I see the following mapping of OVMF binaries to their correspoindg "VARS" file under the 'nvram' section: #nvram = [ # "/usr/share/OVMF/OVMF_CODE.fd:/usr/share/OVMF/OVMF_VARS.fd", # "/usr/share/OVMF/OVMF_CODE.secboot.fd:/usr/share/OVMF/OVMF_VARS.fd", # "/usr/share/AAVMF/AAVMF_CODE.fd:/usr/share/AAVMF/AAVMF_VARS.fd", # "/usr/share/AAVMF/AAVMF32_CODE.fd:/usr/share/AAVMF/AAVMF32_VARS.fd" #] Now let's enumerate the content of 'edk2-ovmf' package: $> rpm -ql edk2-ovmf /usr/share/OVMF /usr/share/OVMF/OVMF_CODE.fd /usr/share/OVMF/OVMF_CODE.secboot.fd /usr/share/OVMF/OVMF_VARS.fd /usr/share/OVMF/OVMF_VARS.secboot.fd /usr/share/OVMF/UefiShell.iso /usr/share/doc/edk2-ovmf /usr/share/doc/edk2-ovmf/README /usr/share/doc/edk2-ovmf/ovmf-whitepaper-c770f8c.txt /usr/share/edk2 /usr/share/edk2/ovmf /usr/share/edk2/ovmf/EnrollDefaultKeys.efi /usr/share/edk2/ovmf/OVMF_CODE.fd /usr/share/edk2/ovmf/OVMF_CODE.secboot.fd /usr/share/edk2/ovmf/OVMF_VARS.fd /usr/share/edk2/ovmf/OVMF_VARS.secboot.fd /usr/share/edk2/ovmf/Shell.efi /usr/share/edk2/ovmf/UefiShell.iso /usr/share/licenses/edk2-ovmf /usr/share/licenses/edk2-ovmf/LICENSE.openssl /usr/share/licenses/edk2-ovmf/License.txt There is the /usr/share/edk2/ovmf/OVMF_VARS.secboot.fd file (which comes with the default UEFI keys enrolled). So, the mapping of OVMF binary to VARS file in the earlier mentioned 'nvram' section should have been: /usr/share/OVMF/OVMF_CODE.secboot.fd:/usr/share/edk2/ovmf/OVMF_VARS.secboot.fd Yes? -- /kashyap

[libvirt] [PATCH] qemu: Simplify interface handling in qemuConnectDomainXMLToNative()
by Michal Privoznik 17 Apr '19

17 Apr '19

Firstly, VIR_STRDUP() accepts NULL, so there is no need to check if the string we want to duplicate is not-NULL. Secondly, virDomainNetSetModelString() also accepts NULL.
