[libvirt] [PATCH] qemu.conf: Make nvram list obsolete

by Michal Privoznik

Now that libvirt has firmware auto selection feature the nvram config knob is more or less obsolete. It still makes sense in cases where distro users are using does not provide FW descriptor files, therefore I'm not removing it.

[libvirt] [PATCH v2 00/11] conf: partial net model enum conversion

by Cole Robinson

v1 here: https://www.redhat.com/archives/libvir-list/2019-January/msg00763.html Changes since v1: - patch #7, case insensitive model input comparison - Add xml2xml testing - compile tested on freebsd12.0 This series partially converts the net->model value from a string to an enum. We wrap the existing ->model string in accessor functions, rename it to ->modelstr, add a ->model enum, and convert internal driver usage bit by bit. At the end, all driver code that is acting on specific network model values is comparing against an enum, not a string. This is only partial because of xen/libxl/xm and qemu drivers, which if they don't know anything particular about the model string will just place it on the qemu command line/xen config and see what happens. So basically if I were to pass in <model type='idontexist'/> qemu would turn that into -device idontexist,... That behavior is untouched by this series, as fully unwinding that will take some more work: * Figuring out all reasonable qemu + xen values that could actually result in a working VM config, and adding them to the enum * Figuring out a long term plan for disabling passthrough entirely. There's some discussion in the v1 thread about this. Some caveats: * vz driver is not compile tested. What's the sdk magic to actually get this building? * net model enum lookup is done case insensitive. this is to maintain the behavior of the vmx and virtualbox drivers, but it's different than all our other enum usage. Cole Robinson (11): tests: Add several net model passthrough tests conf: net: Add wrapper functions for <model> value conf: net: Rename 'model' to 'modelstr' conf: net: Add model enum, and netfront value vz: convert to net model enum bhyve: convert to net model enum qemu: Partially convert to net model enum conf: Make net model enum compare case insensitive vmx: convert to net model enum vbox: Convert to net enum model conf: Add VIR_DOMAIN_DEF_FEATURE_NET_MODEL_STRING src/bhyve/bhyve_command.c | 15 +-- src/bhyve/bhyve_parse_command.c | 10 +- src/conf/domain_conf.c | 111 ++++++++++++++---- src/conf/domain_conf.h | 35 +++++- src/libvirt_private.syms | 4 + src/libxl/libxl_conf.c | 8 +- src/libxl/libxl_domain.c | 1 + src/qemu/qemu_command.c | 13 +- src/qemu/qemu_domain.c | 32 +++-- src/qemu/qemu_domain_address.c | 13 +- src/qemu/qemu_driver.c | 14 ++- src/qemu/qemu_hotplug.c | 15 ++- src/qemu/qemu_parse_command.c | 5 +- src/security/virt-aa-helper.c | 3 +- src/vbox/vbox_common.c | 29 ++--- src/vmx/vmx.c | 55 ++++----- src/vz/vz_driver.c | 7 +- src/vz/vz_sdk.c | 17 ++- src/xenconfig/xen_common.c | 31 ++--- src/xenconfig/xen_sxpr.c | 30 ++--- tests/qemuxml2argvdata/net-many-models.args | 39 ++++++ tests/qemuxml2argvdata/net-many-models.xml | 38 ++++++ tests/qemuxml2argvtest.c | 1 + tests/qemuxml2xmloutdata/net-many-models.xml | 53 +++++++++ tests/qemuxml2xmltest.c | 1 + tests/xlconfigdata/test-net-fakemodel.cfg | 24 ++++ tests/xlconfigdata/test-net-fakemodel.xml | 39 ++++++ tests/xlconfigtest.c | 1 + .../test-paravirt-net-fakemodel.cfg | 13 ++ .../test-paravirt-net-fakemodel.xml | 40 +++++++ .../test-paravirt-net-modelstr.cfg | 13 ++ tests/xmconfigtest.c | 1 + .../xml2sexpr-fv-net-many-models.sexpr | 1 + .../xml2sexpr-fv-net-many-models.xml | 43 +++++++ tests/xml2sexprtest.c | 1 + 35 files changed, 586 insertions(+), 170 deletions(-) create mode 100644 tests/qemuxml2argvdata/net-many-models.args create mode 100644 tests/qemuxml2argvdata/net-many-models.xml create mode 100644 tests/qemuxml2xmloutdata/net-many-models.xml create mode 100644 tests/xlconfigdata/test-net-fakemodel.cfg create mode 100644 tests/xlconfigdata/test-net-fakemodel.xml create mode 100644 tests/xmconfigdata/test-paravirt-net-fakemodel.cfg create mode 100644 tests/xmconfigdata/test-paravirt-net-fakemodel.xml create mode 100644 tests/xmconfigdata/test-paravirt-net-modelstr.cfg create mode 100644 tests/xml2sexprdata/xml2sexpr-fv-net-many-models.sexpr create mode 100644 tests/xml2sexprdata/xml2sexpr-fv-net-many-models.xml -- 2.20.1

[libvirt] On the content of 'nvram' section in /etc/libvirt/qemu.conf

by Kashyap Chamarthy

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()

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.
