[PATCH v2 0/4] Support for dirty-limit live migration
by Hyman Huang 09 Dec '23

09 Dec '23

v2: - mark the VIR_MIGRATE_DIRTY_LIMIT flag since 10.0.0 v1: The dirty-limit functionality for live migration was introduced since qemu>=8.1. In the live migration scenario, it implements the force convergence using the dirty-limit approach, which results in better reliable read performance. A straightforward dirty-limit capability for live migration is added by this patchset. Users might not care about other dirty-limit arguments like "x-vcpu-dirty-limit-period" or "vcpu-dirty-limit," thus do not expose them to Libvirt and Keep the default configurations and values in place. For more details about dirty-limit, please see the following reference: https://lore.kernel.org/qemu- devel/169024923116.19090.10825599068950039132-0(a)git.sr.ht/ Hyman Huang (4): Add VIR_MIGRATE_DIRTY_LIMIT flag qemu_migration: Implement VIR_MIGRATE_DIRTY_LIMIT flag virsh: Add support for VIR_MIGRATE_DIRTY_LIMIT flag NEWS: document support for dirty-limit live migration NEWS.rst | 8 ++++++++ docs/manpages/virsh.rst | 10 +++++++++- include/libvirt/libvirt-domain.h | 5 +++++ src/libvirt-domain.c | 8 ++++++++ src/qemu/qemu_migration.c | 8 ++++++++ src/qemu/qemu_migration.h | 1 + src/qemu/qemu_migration_params.c | 6 ++++++ src/qemu/qemu_migration_params.h | 1 + tools/virsh-domain.c | 10 ++++++++++ 9 files changed, 56 insertions(+), 1 deletion(-) -- 2.39.1

[PATCH v2 0/9] RFC: Add versioned CPUs to libvirt
by Jonathon Jongsma 08 Dec '23

08 Dec '23

For SEV-SNP support we will need to be able to specify versioned CPU models that are not yet available in libvirt. Rather than just adding a versioned CPU or two that would satisfy that immediate need, I decided to try to add versioned CPUs in a more standard way. This series generates CPU definitions for all cpu versions that are defined in upstream qemu (at least for recent Intel and AMD CPUs). libvirt already provides a select subset of these versions as configurable CPU models. But we only include the ones that have defined aliases in qemu, such as EPYC-IBPB. After this patchset, all verisioned cpu models supported by qemu will be available in libvirt. Note that I'm only adding versions that are not already available via their alias. For example, I am not adding an EPYC-v2 CPU model since it is already available as EPYC-IBPB. Changes in v2: - don't make any changes to existing CPU models - drop concept of aliases from libvirt and only provide new versioned models that aren't already available via their qemu alias.

[PATCH v1] qemu_driver: Don't handle the EOF event if monitor changed
by tugy＠chinatelecom.cn 07 Dec '23

07 Dec '23

From: Guoyi Tu <tugy(a)chinatelecom.cn> Currently, libvirt creates a thread pool with only on thread to handle all qemu monitor events for virtual machines, In the cases that if the thread gets stuck while handling a monitor EOF event, such as unable to kill the virtual machine process or release resources, the events of other virtual machine will be also blocked, which will lead to the abnormal behavior of other virtual machines. For instance, when another virtual machine completes a shutdown operation and the monitor EOF event has been queued but remains unprocessed, we immediately destroy and start the virtual machine again, at a later time when EOF event get processed, the processMonitorEOFEvent() will kill the virtual machine that just started. To address this issue, in the processMonitorEOFEvent(), we check whether the current virtual machine's monitor object matches the one at the time the event was generated. If they do not match, we immediately return.
