[PATCH] libxl: support getting and setting parameters for the Credit2
by Dario Faggioli 30 Jan '20

30 Jan '20

With Credit2 being Xen default scheduler, it's definitely the case to allow Credit2's scheduling parameters to be get and set via libvirt. This is easy, as Credit and Credit2 have (at least as of now) the very same parameters ('weight' and 'cap'). So we can just let credit2 pass the scheduler-type check and the same code will work for both.

[PATCH v1 0/2] DAC,SELinux: do not remember/recall labels for
by Daniel Henrique Barboza 29 Jan '20

29 Jan '20

Libvirt is trying to do multiple open() calls in /dev/vfio files, which results in errors inside the security drivers and QEMU returning error 125 when attempting to hotplug a hostdev which belongs to the same IOMMU group as an existing domain hostdev. See patch 2 commit msg for more details. I found this problem when testing a PCI multifunction hotplug implementation. Since this is a problem that can happen in other currently supported scenarios, I decided it was worth sending the fix right away. Michal, I'm CCing you because I mentioned commit 4e95cdcbb3 ("security: Don't remember labels for TPM") in patch 2, which seems to fix a very similar problem. Figured you might want to take a look.

[libvirt-rust] change in coding style to follow rustfmt
by Sahid Orentino Ferdjaoui 29 Jan '20

29 Jan '20

I'm proposing to merge a change [0] so the CI would check whether the source code is well-formatted using rustfmt [1]. The aim is to add an easy convention to follow regarding the coding style. For contributors the natural thing to do before to submit any patches is to verify the format using: `cargo fmt -v -- --check` The support of rustfmt via cargo can be added using: `rustup component add rustfmt` I did not want to pollute the mailing list with such big change which doesn't bring anything. Please let me know if you have any objections. commit 851296786626d61ebec985a9caeb515514955dd8 Author: Sahid Orentino Ferdjaoui <sahid.ferdjaoui(a)canonical.com> Date: Tue Jan 28 15:05:44 2020 +0100 ensure that the code is well formatted using rustfmt. In this commit we add CI rule so travis would check whether the code is well formatted using rustfmt.

[PATCH v2 0/4] lxc: Add suport to network indexes for LXC 3.X
by Julio Faracco 29 Jan '20

29 Jan '20

This series implement support for network syntax settings for LXC 3.X. Now, indexes are part of the settings to define network interfaces. Each interface has its own index. The old style uses 'type' tag to differentiate each interface and with this, it could use one single structure. Now, network interfaces are a single array with interface pointers. Old: lxc.network.type = veth lxc.network.flags = up lxc.network.link = virbr0 New: lxc.net.0.type = veth lxc.net.0.flags = up lxc.net.0.link = virbr0 v1-v2: Moving sscanf to virStrToLong_ull according Daniel's suggestion.
