[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;

[PATCH v3 0/9] ch: support restore with network devices
by Purna Pavan Chandra 09 Aug '24

Current ch driver supports restore only for domains without any network configuration defined. This was because libvirt explicitly passes network fds and CH did not had support to restore with new net FDS. This support has been added recently, https://github.com/cloud-hypervisor/cloud-hypervisor/pull/6402 The changes in this patch series includes moving to socket communication for restore api, create new net fds and pass them via SCM_RIGHTS to CH.

[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.
