[virttools-web PATCH 0/3] Switch www.virt-tools.org over to use GitLab Pages

[PATCH] tools: variables clean-up in libvirt-guests script

by Prathamesh Chavan

Redeclared variables in script functions marked as local. Variables `guest_running` and `guests_shutting_down` in the functions 'guest_is_on` and `check_guests_shutdown` were untouched, as the functions returned values in these variables. Signed-off-by: Prathamesh Chavan <pc44800(a)gmail.com> --- I'm submitting this as my BiteSizedTask for GSoC'20 I've cc'd Martin Kletzander, as he is mentor for this task, and to ensure that the needful was done by me. After running `make check`, I received "PASS: 98 and SKIP: 7" as the result. Travis-ci build report can be found at [1]. For my project, 'Introducing job control to the storage driver', right now I'm going through the `/src/qemu/THREADS.txt` as well as previous work done by Tucker DiNapoli during GSoC'14, as well as the proposal of Taowei Luo for GSoC'15. Their email threads are surely helping me get a better picture of the project. Apart from this, please let me know if there is anything else, which could help me with this project. Thansk!

[PATCH v3 0/3] add support for QEMU 9pfs 'multidevs' option

by Christian Schoenebeck

QEMU 4.2 added a new option 'multidevs' for 9pfs. The following patch adds support for this new option to libvirt. In short, what is this about: to distinguish files uniquely from each other in general, numeric file IDs are typically used for comparison, which in practice is the combination of a file's device ID and the file's inode number. Unfortunately 9p protocol's QID field used for this purpose, currently is too small to fit both the device ID and inode number in, which hence is a problem if one 9pfs export contains multiple devices and may thus lead to misbheaviours on guest (e.g. with SAMBA file servers) in that case due to potential file ID collisions. To mitigate this problem with 9pfs a 'multidevs' option was introduced in QEMU 4.2 for defining how to deal with this, e.g. multidevs=remap will cause QEMU's 9pfs implementation to remap all inodes from host side to different inode numbers on guest side in a way that prevents file ID collisions. NOTE: In the libvirt docs changes of this libvirt patch I simply assumed "since 6.2.0". So the final libvirt version number would need to be adjusted in that text if necessary. See QEMU discussion with following Message-ID for details: 8a2ffe17fda3a86b9a5a437e1245276881f1e235.1567680121.git.qemu_oss(a)crudebyte.com v2->v3: * Rebased to master (SHA-1 e4bf03b8ff). * Auto sense QEMU capability for command line option fsdev.multidevs instead of checking for QEMU version 4.2.

[PATCH 0/4] support for virtio packed virtqueues

by Bjoern Walk

QEMU recently (86044b24e) introduced packed virtqueues for virtio that supposedly have better cache utilization and performance compared to the default split queues. So here's a patch set that expose the virtio parameter as a optional libvirt XML attribute to virtio-backed devices, e.g.: <interface type='user'> <mac address='00:11:22:33:44:55'/> <model type='virtio'/> <driver packed='on'/> </interface> The default value if the attribute is omitted is still 'off' and regular split virtqueues are used.

[PATCH 00/15] move validations out of qemu_domain.c

by Daniel Henrique Barboza

This is a suggestion made by Peter in [1], in the review discussion of a series in which I started moving qemuCaps validation from qemu_command.c to qemu_domain.c [2]. I'll quote here what he said back then: "My only suggestion is that after this we should move all validation into a separate file. qemu_domain was a code dumping place for a long time and since we now have a lot of common code moving it out would be benficial for cleaning up an making it more obvious." This is my first go at it with a new file called 'qemu_validate.c'. The code changes are trivial - just moving stuff from qemu_domain to qemu_validate - but the amount of changes can sure make for really tedious reviews. Patches were split according to my own criteria of how annoying would it be to review each one. The maintainer is, as always, welcome to squash them up as necessary. There are still validations to be moved inside qemu_domain.c after this series. I chose to do this first round to validate the idea instead of rocking a 40-something patch series all of a sudden. Once this is figured out we can proceed with the moving. After all this is settled I intend to continue the work I started in [2], but using qemu_validate.c instead of qemu_domain.c as destination.
