[PATCH 0/3] Intel-IOMMU: Add dma-translation switch
by Sandesh Patel 09 Aug '24

09 Aug '24

Since Qemu commit 8646d9c (Support IR-only mode without DMA translation) version 7.1.0, Qemu support dma-translation attribute for Intel IOMMU. This patch adds a new attribute dma_translation to configure this.

incorrect-array-indexing fix is not present in latest libvirt.org/go/libvirt(v1.10005.0) - SendKey API

Hello, Due to incorrect-array-indexing bug(reported here:https://gitlab.com/libvirt/libvirt-go-module/-/issues/3) I can't send the keycodes to the guest VM using sendkey API. @berrange had fixed this issue 2year ago here: https://gitlab.com/berrange/libvirt-go-module/-/commit/72e49243e57a5f78e404… but the fix is not present in the latest libvirt.org/go/libvirt(v1.10005.0) Any idea when the fix will be available in libvirt.org/go/libvirt ? Thanks Krishna.

[PATCH 2/2] qemu: Introduce the ability to disable the built-in PS/2 controller
by Kamil Szczęk 08 Aug '24

08 Aug '24

A while back QEMU introduced a new machine option for disabling the i8042 PS/2 controller (commit 4ccd5fe22feb95137d325f422016a6473) which up until then was a built-in device included by all PC machine type descendants unconditionally. This new option allowed users to disable emulation of this controller, thus removing the default PS/2 peripherals. The rationale for why somebody might want to disable PS/2 peripherals is explained in the aforementioned commit. This introduces a new 'ps2' feature which, when disabled, results in no implicit PS/2 bus input devices being automatically added to the domain and addition of the 'i8042=off' machine option to the QEMU command-line. A notable side effect of disabling the i8042 controller in QEMU is that the vmport device won't be created. For this reason we will not allow setting the vmport feature if the ps2 feature is explicitly disabled.

[PATCH 1/2] qemu: Improve PS/2 controller detection
by Kamil Szczęk 08 Aug '24

08 Aug '24

Up until now, we've assumed that all x86 machines have a PS/2 controller built-in. This assumption was correct until QEMU v4.2 introduced a new x86-based machine type - microvm. Due to this assumption, a pair of unnecessary PS/2 inputs are implicitly added to all microvm domains. This patch fixes that by whitelisting machine types which are known to include the i8042 PS/2 controller.

Having 'py36' hardcoded here made sure it worked against that particular version even if the user has a different version, but I do not understand the benefit of running it against the current version (as opposed to just running pytest directly). My point was to update the version used in this rule; therefore I supposed, if one version were to be used, the latest of the user would make sense. For all the versions used by tox, this patch addresses particularly that: https://lists.libvirt.org/archives/list/devel@lists.libvirt.org/message/VWW… Ariel Jano > > test: all > tox >-- >2.45.2 >

[PATCH] vsh: Allow vshReadlineInit() to be called multiple times
by Michal Privoznik 08 Aug '24

08 Aug '24

Thing about vshReadlineInit() is - it's called multiple times. The first time from vshInit(), when @ctl was filled only partially (most notably, before any argv parsing is done, hence ctl->imode is set to false). The second time after argv parsing, from virshInit() -> vshInitReload(). In here, ctl->imode might have changed and thus vshReadlineInit() can't exit early - it needs to set up stuff for interactive mode (history basically). To allow vshReadlineInit() to be called again, vshReadlineDeinit() must set @autoCompleteOpaque to NULL.

[PATCH] network: fix crashing "modify" option for hostname
by Adam Julis 08 Aug '24

The original condition caused (after adding modify option) possibly access to not allocated memory. For consistency added new check for multiple same records.

[PATCH] network: NULL check for "modify" DNS-txt records

The "modify" command allowed to replace an existing record, now checks for the NULL string in the new value and throw error if found.
