CFP: KVM Forum 2020

by Paolo Bonzini

================================================================ KVM Forum 2020: Call For Participation October 28-30, 2020 - Convention Centre Dublin - Dublin, Ireland (All submissions must be received before June 15, 2020 at 23:59 PST) ================================================================= KVM Forum is an annual event that presents a rare opportunity for developers and users to meet, discuss the state of Linux virtualization technology, and plan for the challenges ahead. This highly technical conference unites the developers who drive KVM development and the users who depend on KVM as part of their offerings, or to power their data centers and clouds. Sessions include updates on the state of the KVM virtualization stack, planning for the future, and many opportunities for attendees to collaborate. After more than ten years in the mainline kernel, KVM continues to be a critical part of the FOSS cloud infrastructure. Come join us in continuing to improve the KVM ecosystem. We understand that these are uncertain times and we are continuously monitoring the COVID-19/Novel Coronavirus situation. Our attendees' safety is of the utmost importance. If we feel it is not safe to meet in person, we will turn the event into a virtual experience. We hope to announce this at the same time as the speaker notification. Speakers will still be expected to attend if a physical event goes ahead, but we understand that exceptional circumstances might arise after speakers are accepted and we will do our best to accommodate such circumstances. Based on these factors, we encourage you to submit and reach out to us should you have any questions. The program committee may be contacted as a group via email: kvm-forum-2020-pc(a)redhat.com. SUGGESTED TOPICS ---------------- * Scaling, latency optimizations, performance tuning * Hardening and security * New features * Testing KVM and the Linux Kernel: * Nested virtualization * Resource management (CPU, I/O, memory) and scheduling * VFIO: IOMMU, SR-IOV, virtual GPU, etc. * Networking: Open vSwitch, XDP, etc. * virtio and vhost * Architecture ports and new processor features QEMU: * Management interfaces: QOM and QMP * New devices, new boards, new architectures * New storage features * High availability, live migration and fault tolerance * Emulation and TCG * Firmware: ACPI, UEFI, coreboot, U-Boot, etc. Management & Infrastructure * Managing KVM: Libvirt, OpenStack, oVirt, KubeVirt, etc. * Storage: Ceph, Gluster, SPDK, etc. * Network Function Virtualization: DPDK, OPNFV, OVN, etc. * Provisioning SUBMITTING YOUR PROPOSAL ------------------------ Abstracts due: June 15, 2020 Please submit a short abstract (~150 words) describing your presentation proposal. Slots vary in length up to 45 minutes. Submit your proposal here: https://events.linuxfoundation.org/kvm-forum/program/cfp/ Please only use the categories "presentation" and "panel discussion" You will receive a notification whether or not your presentation proposal was accepted by August 17, 2020. Speakers will receive a complimentary pass for the event. In case your submission has multiple presenters, only the primary speaker for a proposal will receive a complimentary event pass. For panel discussions, all panelists will receive a complimentary event pass. TECHNICAL TALKS A good technical talk should not just report on what has happened over the last year; it should present a concrete problem and how it impacts the user and/or developer community. Whenever applicable, focus on work that needs to be done, difficulties that haven't yet been solved, and on decisions that other developers should be aware of. Summarizing recent developments is okay but it should not be more than a small portion of the overall talk. END-USER TALKS One of the big challenges as developers is to know what, where and how people actually use our software. We will reserve a few slots for end users talking about their deployment challenges and achievements. If you are using KVM in production you are encouraged submit a speaking proposal. Simply mark it as an end-user talk. As an end user, this is a unique opportunity to get your input to developers. PANEL DISCUSSIONS If you are proposing a panel discussion, please make sure that you list all of your potential panelists in your the abstract. We will request full biographies if a panel is accepted. HANDS-ON / BOF SESSIONS We will reserve some time for people to get together and discuss strategic decisions as well as other topics that are best solved within smaller groups. These sessions will be announced during the event. If you are interested in organizing such a session, please add it to the list at http://www.linux-kvm.org/page/KVM_Forum_2020_BOF Let people you think who might be interested know about your BOF, and encourage them to add their names to the wiki page as well. Please add your ideas to the list before KVM Forum starts. HOTEL / TRAVEL -------------- This year's event will take place at the Conference Center Dublin. For information on hotels close to the conference, please visit https://events.linuxfoundation.org/kvm-forum/attend/venue-travel/. Information on conference hotel blocks will be available later in Spring 2020.

[PATCH v5 0/4] introduction of migration_version attribute for VFIO live migration

by Yan Zhao

This patchset introduces a migration_version attribute under sysfs of VFIO Mediated devices. This migration_version attribute is used to check migration compatibility between two mdev devices. Currently, it has two locations: (1) under mdev_type node, which can be used even before device creation, but only for mdev devices of the same mdev type. (2) under mdev device node, which can only be used after the mdev devices are created, but the src and target mdev devices are not necessarily be of the same mdev type (The second location is newly added in v5, in order to keep consistent with the migration_version node for migratable pass-though devices) Patch 1 defines migration_version attribute for the first location in Documentation/vfio-mediated-device.txt Patch 2 uses GVT as an example for patch 1 to show how to expose migration_version attribute and check migration compatibility in vendor driver. Patch 3 defines migration_version attribute for the second location in Documentation/vfio-mediated-device.txt Patch 4 uses GVT as an example for patch 3 to show how to expose migration_version attribute and check migration compatibility in vendor driver. (The previous "Reviewed-by" and "Acked-by" for patch 1 and patch 2 are kept in v5, as there are only small changes to commit messages of the two patches.) v5: added patch 2 and 4 for mdev device part of migration_version attribute. v4: 1. fixed indentation/spell errors, reworded several error messages 2. added a missing memory free for error handling in patch 2 v3: 1. renamed version to migration_version 2. let errno to be freely defined by vendor driver 3. let checking mdev_type be prerequisite of migration compatibility check 4. reworded most part of patch 1 5. print detailed error log in patch 2 and generate migration_version string at init time v2: 1. renamed patched 1 2. made definition of device version string completely private to vendor driver 3. reverted changes to sample mdev drivers 4. described intent and usage of version attribute more clearly. Yan Zhao (4): vfio/mdev: add migration_version attribute for mdev (under mdev_type node) drm/i915/gvt: export migration_version to mdev sysfs (under mdev_type node) vfio/mdev: add migration_version attribute for mdev (under mdev device node) drm/i915/gvt: export migration_version to mdev sysfs (under mdev device node) .../driver-api/vfio-mediated-device.rst | 183 ++++++++++++++++++ drivers/gpu/drm/i915/gvt/Makefile | 2 +- drivers/gpu/drm/i915/gvt/gvt.c | 39 ++++ drivers/gpu/drm/i915/gvt/gvt.h | 7 + drivers/gpu/drm/i915/gvt/kvmgt.c | 55 ++++++ drivers/gpu/drm/i915/gvt/migration_version.c | 170 ++++++++++++++++ drivers/gpu/drm/i915/gvt/vgpu.c | 13 +- 7 files changed, 466 insertions(+), 3 deletions(-) create mode 100644 drivers/gpu/drm/i915/gvt/migration_version.c -- 2.17.1

[PATCH libvirt v1 0/6] Fix ZPCI address auto-generation on s390

by Shalini Chellathurai Saroja

The ZPCI address validation or autogeneration does not work as expected in the following scenarios 1. uid = 0 and fid = 0 2. uid = 0 and fid > 0 3. uid = 0 and fid not specified 4. uid not specified and fid > 0 5. 2 ZPCI devices with uid > 0 and fid not specified. This is because of the following reasons 1. If uid = 0 or fid = 0 the code assumes that user has not specified the corresponding address 2. If either uid or fid is provided, the code assumes that both uid and fid addresses are specified by the user. This patch fixes these issues. Shalini Chellathurai Saroja (6): conf: fix ZPCI address validation on s390 tests: qemu: add tests for ZPCI on s390 conf: fix ZPCI address auto-generation on s390 qemu: move ZPCI uid validation into device validation tests: qemu: add more tests for ZPCI on S390 tests: add test with PCI and CCW device src/conf/device_conf.c | 45 ++++++-------- src/conf/domain_addr.c | 59 +++++++++++++------ src/conf/domain_conf.c | 2 +- src/libvirt_private.syms | 4 +- src/qemu/qemu_validate.c | 26 +++++++- src/util/virpci.c | 23 ++------ src/util/virpci.h | 6 +- .../hostdev-vfio-zpci-autogenerate-fids.args | 31 ++++++++++ .../hostdev-vfio-zpci-autogenerate-fids.xml | 29 +++++++++ .../hostdev-vfio-zpci-autogenerate-uids.args | 31 ++++++++++ .../hostdev-vfio-zpci-autogenerate-uids.xml | 29 +++++++++ .../hostdev-vfio-zpci-ccw-memballoon.args | 28 +++++++++ .../hostdev-vfio-zpci-ccw-memballoon.xml | 17 ++++++ .../hostdev-vfio-zpci-duplicate.xml | 30 ++++++++++ ...ostdev-vfio-zpci-invalid-uid-valid-fid.xml | 21 +++++++ .../hostdev-vfio-zpci-multidomain-many.args | 6 +- .../hostdev-vfio-zpci-set-zero.xml | 21 +++++++ .../hostdev-vfio-zpci-uid-set-zero.xml | 20 +++++++ tests/qemuxml2argvtest.c | 25 ++++++++ .../hostdev-vfio-zpci-multidomain-many.xml | 6 +- 20 files changed, 387 insertions(+), 72 deletions(-) create mode 100644 tests/qemuxml2argvdata/hostdev-vfio-zpci-autogenerate-fids.args create mode 100644 tests/qemuxml2argvdata/hostdev-vfio-zpci-autogenerate-fids.xml create mode 100644 tests/qemuxml2argvdata/hostdev-vfio-zpci-autogenerate-uids.args create mode 100644 tests/qemuxml2argvdata/hostdev-vfio-zpci-autogenerate-uids.xml create mode 100644 tests/qemuxml2argvdata/hostdev-vfio-zpci-ccw-memballoon.args create mode 100644 tests/qemuxml2argvdata/hostdev-vfio-zpci-ccw-memballoon.xml create mode 100644 tests/qemuxml2argvdata/hostdev-vfio-zpci-duplicate.xml create mode 100644 tests/qemuxml2argvdata/hostdev-vfio-zpci-invalid-uid-valid-fid.xml create mode 100644 tests/qemuxml2argvdata/hostdev-vfio-zpci-set-zero.xml create mode 100644 tests/qemuxml2argvdata/hostdev-vfio-zpci-uid-set-zero.xml -- 2.21.1

[PATCH v2 1/3] libxl: Add 'permissive' option for PCI devices

by Marek Marczykowski-Górecki

From: Simon Gaiser <simon(a)invisiblethingslab.com> By setting the permissive flag the Xen guest access to the PCI config space is not filtered. This might be a security risk, but it's required for some devices and the IOMMU and interrupt remapping should (mostly?) contain it. Because of it (and that the attribute is Xen only), in an example include "permissive='no'" - to not expose users copying from documentation to extra risk. Example usage: <devices> ... <hostdev mode='subsystem' type='pci' managed='yes' permissive='yes'> <source> <address domain='0x0000' bus='0x06' slot='0x02' function='0x0'/> </source> </hostdev> </devices> Signed-off-by: Simon Gaiser <simon(a)invisiblethingslab.com> Signed-off-by: Marek Marczykowski-Górecki <marmarek(a)invisiblethingslab.com> --- Changes in v2: - improve documentation (version info, example) - update schema - use virTristateBool - add a test - improve commit message - news entry --- docs/formatdomain.html.in | 7 +++++-- docs/news.xml | 11 +++++++++++- docs/schemas/domaincommon.rng | 10 ++++++++++- src/conf/domain_conf.c | 19 +++++++++++++++++++- src/conf/domain_conf.h | 1 +- src/libxl/libxl_conf.c | 1 +- tests/libxlxml2domconfigdata/moredevs-hvm.json | 6 ++++++- tests/libxlxml2domconfigdata/moredevs-hvm.xml | 5 +++++- 8 files changed, 58 insertions(+), 2 deletions(-) diff --git a/docs/formatdomain.html.in b/docs/formatdomain.html.in index c530573..0d1146e 100644 --- a/docs/formatdomain.html.in +++ b/docs/formatdomain.html.in @@ -4987,7 +4987,7 @@ <pre> ... <devices> - <hostdev mode='subsystem' type='pci' managed='yes'> + <hostdev mode='subsystem' type='pci' managed='yes' permissive='no'> <source> <address domain='0x0000' bus='0x06' slot='0x02' function='0x0'/> </source> @@ -5082,7 +5082,10 @@ (or <code>virsh nodedev-detach</code> before starting the guest or hot-plugging the device and <code>virNodeDeviceReAttach</code> (or <code>virsh nodedev-reattach</code>) after hot-unplug or - stopping the guest. + stopping the guest.

[PATCH v2 00/40] convert virObjects to GObject

by Rafael Fonseca

This patch series convert various simple instances of virObject to a GObject equivalent. virLockableObject and virObjects which are subclassed will be covered in future patchsets. New in v2: - use *Dispose for unreffing objects and *Finalize for freeing data, as suggested in the GLib documentation - use `g_clear_object` instead of `if + g_object_unref` - properly update gendispatch as types are converted - virDomain is now converted to GObject too - added a helper function for freeing array of GObjects - added previously missed conversion spots Rafael Fonseca (40):
