[libvirt PATCH] util: Improve comment for workaround

[PATCH 0/2] gitlab: Adapt name of CI job building the web page to 'pages'
by Peter Krempa 04 May '23

04 May '23

The subject is deliberately chosen so that it does not imply that we actually want to host libvirt.org via gitlab pages at this time. It's not possible as gitlab pages don't allow redirects to different domains: https://gitlab.com/gitlab-org/gitlab-pages/-/issues/601 The merit of this change was discussed here: https://gitlab.com/libvirt/libvirt-ocaml/-/merge_requests/23#note_1360494690 Along with this patch, a change to to the job deploying the page on libvirt.org will be needed.

[PATCH v1] use libexecdir as location for qemu-bridge-helper
by Olaf Hering 02 May '23

02 May '23

The current logic in meson.build assumes a fixed runtime path for qemu-bridge-helper in case this binary is not available during build. Since qemu-bridge-helper is not used during build it is not required to have it installed at build time. It is likely that both qemu and libvirt are built with the same --libexecdir option. So use this as the expected location for qemu-bridge-helper.

Release of libvirt-9.3.0
by Jiri Denemark 02 May '23

02 May '23

The 9.3.0 release of both libvirt and libvirt-python is tagged and signed tarballs and source RPMs are available at https://download.libvirt.org/ https://download.libvirt.org/python/ Thanks everybody who helped with this release by sending patches, reviewing, testing, or providing feedback. Your work is greatly appreciated. * New features * qemu: Introduce support for ``igb`` network interface model ``igb`` is a successor to the ``e1000e`` network device using PCIe interface. It was introduced in QEMU 8.0 * qemu: Improve handling of maximum physical address configuration * Improvements * qemu: Change default machine type for ARM and RISC-V ARM and RISC-V architectures now use the ``virt`` machine type by default. The previous defaults were nearly unusable and had to be overridden in most cases. * Improve translatable strings format substitutions All translatable error messages with substitution strings were converted to use positional modifiers to allow translators to shuffle around words in the translation. The translations in Weblate were also updated to match. * qemu: Improve validation of ``watchdog`` devices Certain invalid configurations of ``watchdog`` device are now properly detected: - hotplug of always-present platform watchdogs is forbidden - ``iTCO`` watchdog can be configured only once - ``ib700`` watchdog is allowed only on ``i440fx`` machines * Improved output of ``virt-host-validate`` on ARM Our validation tool now parses the ``IORT`` data on ARM to properly detect presence of SMMU and other features. * Bug fixes * qemu: Fix inactive internal snapshots of VM with UEFI firmware Recent changes to UEFI firmware handling resulted into breaking support for inactive internal snapshots of VMs with UEFI which historically worked. (Although the intention was to disallow them together with active ones, but the check did not work properly.) Preserve existing functionality by allowing such snapshots explicitly. * qemu: Properly configure locked memory limit for VMs with ``<disk type='nvme'`` The NVMe driver in qemu requires some memory to be locked. This was not taken into account in the code which calculates the memory limits based on devices present in the configuration * Fix native build on win32 Various improvements to the build system now allow users to build the client library of libvirt on win32 natively. * qemu: Properly detect tray of hotplugged CD-ROM devices Media in a CD-ROM device which was hotplugged could not be changed as the presence of the tray was not detected properly on hotplug. Enjoy. Jirka

[PATCH v3 00/10] Deprecate/rename singlestep command line option, monitor interfaces
by Peter Maydell 02 May '23

02 May '23

The command line option '-singlestep' and its HMP equivalent the 'singlestep' command are very confusingly named, because they have nothing to do with single-stepping the guest (either via the gdb stub or by emulation of guest CPU architectural debug facilities). What they actually do is put TCG into a mode where it puts only one guest instruction into each translation block. This is useful for some circumstances such as when you want the -d debug logging to be easier to interpret, or if you have a finicky guest binary that wants to see interrupts delivered at something other than the end of a basic block. The confusing name is made worse by the fact that our documentation for these is so minimal as to be useless for telling users what they really do. This series: * changes the command line interface: for user-mode emulators, the new option is '-one-insn-per-tb', and for system mode emulators it is a TCG accel property '-accel tcg,one-insn-per-tb=on' * updates all the places which currently directly touch the 'singlestep' global variable to instead get the current accelerator and query/set the QOM property (except the one internal to TCG itself in curr_cflags()) * documents that the old -singlestep option is deprecated * adds a new HMP command 'one-insn-per-tb', and deprecates the old 'singlestep' command. (Strictly we don't need to deprecate HMP commands, but I'd already written the code for v1 of this series and it's a minor user convenience.) * moves the 'is one-insn-per-tb on?' info from 'info status' to 'info jit' * deprecates the 'singlestep' member of the QMP StatusInfo type, with no replacement. (We have a sketch of a design of how we might provide this in QMP if we need to, but I'm pretty sure nobody using QMP is actually using the info in the 'singlestep' field, especially since it's always been wrongly documented and there's no write interface, only a read one.) Changes v2->v3: * curr_cflags() is a hot path, so use a global variable so it doesn't have to fetch the current accelerator object. (NB: I haven't done the tcg_global_cflags thing suggested in review of v2; justification in the below-the-fold part of the patch 3 commit message notes.) * put the new line in test-hmp.c in its proper alphabetical order place in patch 8 * in patch 10 don't provide a replacement field in the QMP StatusInfo type, just deprecate the old one * I finally tested that bsd-user compiles, and fixed the missing-close-bracket error in that patch :-) Patches still needing review: 3, 7, 10 thanks -- PMM Peter Maydell (10): make one-insn-per-tb an accel option softmmu: Don't use 'singlestep' global in QMP and HMP commands accel/tcg: Use one_insn_per_tb global instead of old singlestep global linux-user: Add '-one-insn-per-tb' option equivalent to '-singlestep' bsd-user: Add '-one-insn-per-tb' option equivalent to '-singlestep' Document that -singlestep command line option is deprecated accel/tcg: Report one-insn-per-tb in 'info jit', not 'info status' hmp: Add 'one-insn-per-tb' command equivalent to 'singlestep' qapi/run-state.json: Fix missing newline at end of file hmp: Deprecate 'singlestep' member of StatusInfo docs/about/deprecated.rst | 39 +++++++++++++++++++++++++++++++++++++ docs/user/main.rst | 14 +++++++++++-- qapi/run-state.json | 16 +++++++++++---- accel/tcg/internal.h | 2 ++ include/exec/cpu-common.h | 2 -- include/monitor/hmp.h | 2 +- accel/tcg/cpu-exec.c | 2 +- accel/tcg/monitor.c | 14 +++++++++++++ accel/tcg/tcg-all.c | 23 ++++++++++++++++++++++ bsd-user/main.c | 14 ++++++++----- linux-user/main.c | 18 +++++++++++------ softmmu/globals.c | 1 - softmmu/runstate-hmp-cmds.c | 25 ++++++++++++++++++------ softmmu/runstate.c | 10 +++++++++- softmmu/vl.c | 17 ++++++++++++++-- tests/qtest/test-hmp.c | 1 + hmp-commands.hx | 25 ++++++++++++++++++++---- qemu-options.hx | 12 ++++++++++-- tcg/tci/README | 2 +- 19 files changed, 201 insertions(+), 38 deletions(-) -- 2.34.1

Greetings, I'm trying to boot a VM with pi of the on sound card and the gpu using libvirt[1] and qemu I have a script that loads the needed KVM mods, starts libvirt and press the HDD Then starts the VM with virus. I've configured qemu hooks to run scripts in the relevant events. In prepare, I disable active ui, unbind the screen and consoles, unload all the mods of the hw and load the vfio mods with the IDs of the devs and allow unsafe intrs. Then libvirt tries to start the VM and fails with the this error: error: Failed to start domain 'win_user_home' error: internal error: qemu unexpectedly closed the monitor: 2023-05-01T14:59:49.968252Z qemu-system-x86_64: -device {"driver":"vfio-pci","host":"0000:05:00.0","id":"hostdev0","bus":"pci.5","multifunction":true,"addr":"0x0"}: vfio 0000:05:00.0: failed to setup container for group 14: Failed to set iommu for container: Operation not permitted The GPU has its own iommu group[2] and I pass the soundcard too. Why am I getting this error? I did got the VM to start in earlier more simple setup with less devices so I know it boots. thanks, Dagg 1. xml file: <domain type='kvm'> <name>win_user_home</name>
