[PATCH] conf: Check for bandwidth limits during parsing
by Michal Privoznik 13 Aug '24

13 Aug '24

The 'tc' program stores speeds in 64bit integers (unit is bytes per second) and sizes in uints (unit is bytes). We use different units: kilobytes per second and kibibytes and therefore we can parse values larger than 'tc' can handle. Reject those values right away. And while at it, fix the schema which assumed speed values fit into uint.

[PATCH] virnetlibsshsession: Reflect API change in libssh
by Michal Privoznik 12 Aug '24

12 Aug '24

As of libssh commit of libssh-0.11.0~70 [1] the ssh_channel_get_exit_status() function is deprecated and a new one is introduced instead: ssh_channel_get_exit_state(). It's not a drop-in replacement, but it's simple enough.

[PATCH] glibcompat: remove obsolete clang workaround
by Daniel P. Berrangé 12 Aug '24

12 Aug '24

This mostly reverts commit 65491a2dfe00bfcf9f09a8d6eab60234b56c8cc4. There was a bug introduced in glib 2.67.0 which impacted libvirt with clang causing -Wincompatible-pointer-types-discards-qualifiers warnings. This was actually fixed quite quickly in 2.67.1 with https://gitlab.gnome.org/GNOME/glib/-/merge_requests/1719 Our workaround was then broken with glib 2.81.1 due to commit 14b3d5da9019150d821f6178a075d85044b4c255 changing the signature of the (private) macro we were overriding. Since odd-number glib releases are development snapshots, and the original problem was only present in 2.67.0 and no other releases, just drop the workaround entirely. Signed-off-by: Daniel P.

[PATCH v2 0/6] qemu: Introduce the ability to disable the built-in PS/2 controller
by Kamil Szczęk 11 Aug '24

11 Aug '24

A while back QEMU introduced a new machine property for disabling the i8042 PS/2 controller (commit 4ccd5fe22feb95137d325f422016a6473541fe9f) 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 series of patches exposes this machine property via the 'ps2' feature, while also taking care of side-effects, such as inhibiting the implicit creation of PS/2 inputs in the domain XML. Changes from v1: - Use abstract 'generic-pc' machine type instead of concrete 'pc' for property detection. - Introduce test cases along with monitor replies and capability flags. - Add NEWS mention of the new feature.

[PATCH v2] vmx: Ensure unique disk targets when parsing
by Adam Julis 09 Aug '24

09 Aug '24

Disk targets are generated in virVMXParseConfig() with virVMXGenerateDiskTarget(). It works on combination of controller, fix offset, unit and prefix. While SCSI and SATA have same prefix "sd", function virVMXGenerateDiskTarget() could returned in some cases same targets. In this patch, after loaded SCSI and SATA disks to the def, indexes are regenerated, now simply from position of the disk in array of disks (def). With this, required uniqueness is guaranteed. Because assigned addresses of disks are generated from their indexes, for every changed SATA disk is called virDomainDiskDefAssignAddress() with the updated value. The corresponding tests have been modified to match the index changes. Signed-off-by: Adam Julis <ajulis(a)redhat.com> --- Since previous version in mailing list was complicated for trying to preserve the indexes of SCSI and previous tests, this one going to straightforward, although it changes all (SCSI and SATA) indexes. It's not a bug, since we cannot guarantee the same naming inside the guest anyway. src/vmx/vmx.c | 19 +++++++++++++++++++ tests/vmx2xmldata/esx-in-the-wild-11.xml | 4 ++-- tests/vmx2xmldata/esx-in-the-wild-12.xml | 4 ++-- tests/vmx2xmldata/esx-in-the-wild-2.xml | 4 ++-- tests/vmx2xmldata/esx-in-the-wild-8.xml | 4 ++-- tests/vmx2xmldata/scsi-driver.xml | 12 ++++++------ 6 files changed, 33 insertions(+), 14 deletions(-) diff --git a/src/vmx/vmx.c b/src/vmx/vmx.c index 227744d062..22e59726c8 100644 --- a/src/vmx/vmx.c +++ b/src/vmx/vmx.c @@ -1400,6 +1400,7 @@ virVMXParseConfig(virVMXContext *ctx, virCPUDef *cpu = NULL;
