[PATCH] docs: manpages: Strip table of contents from manpages
by Peter Krempa 23 Sep '20

23 Sep '20

After meson conversion the man pages started to contain the table of contents. In autoconf we prevented this by a 'grep -v ::contents' in the command building the manpages. A more cultured solution is to strip out the 'contents' docutils element directly. Reported-by: Daniel P.

[PATCH v2] docs/system: clarify deprecation schedule
by Stefan Hajnoczi 23 Sep '20

23 Sep '20

The sentence explaining the deprecation schedule is ambiguous. Make it clear that a feature deprecated in the Nth release is guaranteed to remain available in the N+1th release. Removal can occur in the N+2nd release or later. As an example of this in action, see commit 25956af3fe5dd0385ad8017bc768a6afe41e2a74 ("block: Finish deprecation of 'qemu-img convert -n -o'"). The feature was deprecated in QEMU 4.2.0. It was present in the 5.0.0 release and removed in the 5.1.0 release. Suggested-by: Daniel P.

[PATCH v2] util: support PCI passthrough net device stats collection
by zhenwei pi 23 Sep '20

23 Sep '20

Collect PCI passthrough net device stats from kernel by netlink API. Currently, libvirt can not get PCI passthrough net device stats, run command: #virsh domifstat instance --interface=52:54:00:2d:b2:35 error: Failed to get interface stats instance 52:54:00:2d:b2:35 error: internal error: Interface name not provided The PCI device(usually SR-IOV virtual function device) is detached while it's used in PCI passthrough mode. And we can not parse this device from /proc/net/dev any more. In this patch, libvirt check net device is VF of not firstly, then query virNetDevVFInterfaceStats(new API). virNetDevVFInterfaceStats parses VFs info of all PFs, compares MAC address until the two MAC addresses match. '#ip -s link show' can get the same result. Instead of parsing the output result, implement this feature by libnl API. Notice that this feature deponds on driver of PF. Test on Mellanox ConnectX-4 Lx, it works well. Also test on Intel Corporation 82599ES, it works, but only get 0. (ip-link command get the same result).
