[PATCH 0/5] multiple memory backend support for CPR Live Updates
by mgalaxy＠akamai.com 06 Mar '24

06 Mar '24

From: Michael Galaxy <mgalaxy(a)akamai.com> CPR-based support for whole-hypervisor kexec-based live updates is making progress on qemu-devel. In support of this, we need NUMA to be support in these kinds of environments. To do this we use a technology called PMEM (persistent memory), which underpin the ability for CPR Live Updates to work so that QEMU memory can remain in RAM and be recovered after the kexec has completed. Our systems are highly NUMA-aware, and so this patch series enables NUMA awareness for live update and also allows live migrations to work. Further, we make a small change that allows live migrations to work between *non* PMEM-based systems and PMEM-based systems (and vice-versa). This allows for seemless upgrades from non-live-compatible systems to live-update-compatible sytems without any downtime. Michael Galaxy (5): qemu.conf changes to support multiple memory backend directories Update cleanup routines to handle multiple memory backing paths instead of just one. Implement multiple memory backing paths Support live migration between file-backed memory and anonymous memory.

[PATCH 00/25] qemu: Remove use of '-usb' to instantiate controllers
by Peter Krempa 06 Mar '24

06 Mar '24

This patchset removes the use of '-usb' legacy controller specification. For the vast majority of platforms/machines (most of the irrelevant ones) which don't actually have a concept of implicit USB qemu ignores the '-usb' argument. For the relevant platforms libvirt would already pick exactly the same controller and thus '-usb' wouldn't be used at all. There's a small handful of ARM boards 'realview' and 'versatilepb' where libvirt would pick the wrong one as default if some controllers were compiled out and thus reallistically '-usb' would have effect for those although would be unusable as libvirt's bus name for the bus is incorret and thus no devices would be usable. For the two mostly obsolete board types this series can break ABI in the aforementioned corner case. Other than that this removes all the legacy code which makes USB controller selection utterly confusing. Peter Krempa (25): tests: Replace mentions of the removed 'qemucapabilitiesnumbering' tool qemucapabilitiesdata: Document faked caps dumps testutilshostcpus: Add support for VIR_ARCH_ARMV7L

[PATCH 01/14] hw/core/machine-smp: Remove deprecated "parameter=0" SMP configurations
by Zhao Liu 06 Mar '24

06 Mar '24

From: Zhao Liu <zhao1.liu(a)intel.com> The "parameter=0" SMP configurations have been marked as deprecated since v6.2. For these cases, -smp currently returns the warning and adjusts the zeroed parameters to 1 by default. Remove the above compatibility logic in v9.0, and return error directly if any -smp parameter is set as 0.

[GSOC] Handshake
by Mostafa ali 05 Mar '24

05 Mar '24

Hello lovely people, hope you are all well! I'm looking to contribute to libvirt during the upcoming GSOC 2024, specifically to the XML fuzzing idea. Little about me: I'm a recent graduate of Cairo University, Department of Computer Engineering. I'm extremely interested in all things involving programming languages, compilers, interpreters or metaprogramming and systems programming in general. I'm currently teaching part-time at my university. After reading your GSOC FAQ and the 4 libvirt-specific requirements listed, I have compiled libvirt on my machine and the tests do seem to have run successfully if ninja's terminal logging is to be trusted. After (obviously!) subscribing to your development list, it now remains to have an upstream contribution and the interview. 1- Regarding the interview, the FAQ says it will probably be conducted over IRC. I haven't used IRC before, currently reading up on how to use it. Any specific advice/irc client/guide regarding that ? Also, will the interview be conducted before the acceptance of the contribution or after it ? 2- Regarding the required contribution, I see here https://gitlab.com/libvirt/libvirt/-/issues?label_name=bitesizedtask 2 issues that look interesting, the one about converting the json parsing library and another about switching the code to use Glib's autofree instead of malloc and free. The json one looks more interesting (and difficult!) but it looks like it was already assigned to someone else (and also that it's a whole other GSOC project ?). So is the autofree one suitable as a good first issue for me? That's all. Sorry for any inconvenience and many thanks for your time. Regards, Mostafa

[PATCH v2] storage: Upgrade default qcow2 version
by Abhiram Tilak 05 Mar '24

05 Mar '24

Change the default to modern qcow2 as it's supported by all qemu versions supported by libvirt and `qemu-img` already defaults to the new format since QEMU 1.7. Some Unittests require changes to pass, now that version 1.1 is default. Unittests like `qcow2-1.1.argv` may not be relevant anymore, but this patch doesn't affect them.

[PATCH v2] storage: Upgrade default qcow2 version
by Abhiram Tilak 05 Mar '24

05 Mar '24

Change the default to modern qcow2 as it's supported by all qemu versions supported by libvirt and `qemu-img` already defaults to the new format since QEMU 1.7. Some Unittests require changes to pass, now that version 1.1 is default. Unittests like `qcow2-1.1.argv` may not be relevant anymore, but this patch doesn't affect them.

[PATCH] virsh: Fix overflow error of freepages command
by Adam Julis 05 Mar '24

05 Mar '24

Trying to print pages of a size larger than the UINT_MAX of the given platform (for example, around 4G on 64-bit intel), a system error was printed, but this is a legitimate request, fixed. vshCommandOptScaledInt requiers set maximum returning size for the variable '&bytes'. It was set as UINT_MAX, while the public API variable 'kibibytes', which loads the 'bytes' lately, is type of UINT. Since it's kibibytes, the value in bytes should be 1024* bigger and it still will works correctly. So the correct max size of bytes is UINT_MAX * 1024.

[PATCH 0/2] storage: Upgrade default qcow2 verion to 1.1
by Abhiram Tilak 05 Mar '24

05 Mar '24

Right now the default qcow2 version if not specified explicitly, defaults to 0.10. Certain features like live snapshots, cluster size specification require 1.1 to work. This patch series aims at upgrading the qcow2 default image version, and use compatibility version 1.1 unless specified. This also requires correcting multiple testcases related to this compat version. If any other locations require changing, they will be added as a part of this series. Resolves: https://gitlab.com/libvirt/libvirt/-/issues/602 Abhiram Tilak (2): storage: change assigning qcow2 compat to 1.1 from 0.10 automatically storage: fix testcases on changing the default qcow2 compat to 1.1 src/storage/storage_util.c | 2 +- .../storagevolxml2argvdata/luks-convert-encrypt2fileqcow2.argv | 2 +- tests/storagevolxml2argvdata/qcow2-compat.argv | 2 +- tests/storagevolxml2argvdata/qcow2-from-logical-compat.argv | 2 +- tests/storagevolxml2argvdata/qcow2-luks-convert-encrypt.argv | 2 +- .../qcow2-luks-convert-encrypt2fileqcow2.argv | 2 +- tests/storagevolxml2argvdata/qcow2-luks.argv | 2 +- .../qcow2-nobacking-convert-prealloc-compat.argv | 2 +- .../storagevolxml2argvdata/qcow2-nobacking-prealloc-compat.argv | 2 +- .../qcow2-nocapacity-convert-prealloc.argv | 2 +- tests/storagevolxml2argvdata/qcow2-nocapacity.argv | 2 +- tests/storagevolxml2argvdata/qcow2-nocow-compat.argv | 2 +- tests/storagevolxml2argvdata/qcow2-zerocapacity.argv | 2 +- 13 files changed, 13 insertions(+), 13 deletions(-) -- 2.42.1
