[libvirt PATCH v3 0/4] Ask qemu about migration blockers
by Eugenio Pérez 20 Jul '22

20 Jul '22

There are some hardcoded migration blockers in libvirt, like having a net vhost-vdpa device. While it's true that they cannot be migrated at the moment, there are plans to be able to migrate them soon. They'll put a migration blockers in the cases where you cannot migrate them. Ask qemu about then before rejecting the migration. In case the question is not possible, assume they're not migratable. v3: * Return ok in qemuMonitorJSONGetMigrationBlockers is there are no blockers. * Fix indentation * Report all blockers instead of only the first. * Squash some patches * Move note to function doc. * s/QEMU_MIGRATION_BLOCKED_REASONS/QEMU_CAPS_MIGRATION_BLOCKED_REASONS/ v2: * Ask qemu if it has some pending blockers before try the migration Eugenio Pérez (3): qemu_monitor: add support for get qemu migration blockers qemu_migration: get migration blockers before hardcoded checks qemu_migration: Do not forbid vDPA devices if can query blockers Jonathon Jongsma (1): qemu: introduce capability QEMU_CAPS_MIGRATION_BLOCKED_REASONS src/qemu/qemu_capabilities.c | 2 + src/qemu/qemu_capabilities.h | 1 + src/qemu/qemu_migration.c | 38 +++++++++++++++- src/qemu/qemu_monitor.c | 11 +++++ src/qemu/qemu_monitor.h | 4 ++ src/qemu/qemu_monitor_json.c | 43 +++++++++++++++++++ src/qemu/qemu_monitor_json.h | 3 ++ .../caps_6.0.0.aarch64.xml | 1 + .../qemucapabilitiesdata/caps_6.0.0.s390x.xml | 1 + .../caps_6.0.0.x86_64.xml | 1 + .../caps_6.1.0.x86_64.xml | 1 + .../caps_6.2.0.aarch64.xml | 1 + .../qemucapabilitiesdata/caps_6.2.0.ppc64.xml | 1 + .../caps_6.2.0.x86_64.xml | 1 + .../caps_7.0.0.aarch64.xml | 1 + .../qemucapabilitiesdata/caps_7.0.0.ppc64.xml | 1 + .../caps_7.0.0.x86_64.xml | 1 + .../caps_7.1.0.x86_64.xml | 1 + 18 files changed, 112 insertions(+), 1 deletion(-) -- 2.31.1

[PATCH] schemas: Update ref acpi for devices

[PATCH] qemu: domainjob: remove async variable from qemuDomainObjBeginJobInternal()
by Kristina Hanicova 20 Jul '22

This patch removes variable 'async', which is used only once, and replaces it with direct comparison with an enum member.

[libvirt PATCH] nodedev: support 'mtty' device for testing
by Jonathon Jongsma 20 Jul '22

20 Jul '22

It would be nice to be able to test the mediated device capabilities without having physical hardware which supports it. The 'mtty' kernel module presents a virtual parent device which is capable of creating 'fake' mediated devices, and as such it would be useful for testing. However, the 'mtty' device is not part of an existing device subsystem (e.g. PCI, etc), so libvirt ignores it and it does not get added to the node device list. And because it does not get added to the node device list, it cannot be used to create child mdevs using `virsh nodedev-create`. There is already a node device type capability VIR_NODE_DEV_CAP_MDEV_TYPES that indicates whether a device supports creating child mediated devices, but libvirt assumes that this is a nested capability (in other words, it assumes that the primary capability of a device is something like PCI). If we allow this MDEV_TYPES capability to be a primary device capability, then we can support virtual devices like 'mtty' as a parent for mediated devices.
