[libvirt] set link state for ethernet network devices
by Vasiliy Tolstov 17 May '17

17 May '17

Hi! Sometimes ago i'm write patch for setting link state of network interface for ethernet type (tap). Now i'm try libvirt 3.3.0 and see, that tap interfaces is up but in xml i'm try to specify <link state='down'> also i'm try <source><link state='down'></source> Nothing changed. Laine says, that link state is only for internal representation, and to modify link state on host side i need to specify <source><link state='down'></source>. For history please check email thread "qemu: remove unnecessary setting of tap device online state" So does this bug or it my mistake? Thanks! -- Vasiliy Tolstov, e-mail: v.tolstov(a)selfip.ru

[libvirt] [PATCH v3] qemu: Report shutdown event details
by Martin Kletzander 16 May '17

16 May '17

QEMU will likely report the details of it shutting down, particularly whether the shutdown was initiated by the guest or host. We should forward that information along, at least for shutdown events. Reset has that as well, however that is not a lifecycle event and would add extra constants that might not be used. It can be added later on. Since the only way we can extend information provided to the user is adding event details, we might as well emit multiple events (one with the reason for the shutdown and keep the one for the shutdown being finished for clarity and compatibility).

[libvirt] limit pps via bandwidth

Hi. I have a problem that some vps generate very big pps (500000). I want to limit it for some reasonable value. iptables does not support by default limit by pps more that 10000, i can use nft... but Why not use tc for this ? http://www.lartc.org/manpages/tc-pbfifo.html http://man7.org/linux/man-pages/man8/tc-sfb.8.html As i understand firstly we can limit by pps and secondly via bandwidth...

[libvirt] [PATCH v3] qemu: improve detection of UNIX path generated by libvirt
by Pavel Hrdina 16 May '17

16 May '17

Currently we consider all UNIX paths with specific prefix as generated by libvirt, but that's a wrong assumption. Let's make the detection better by actually checking whether the whole path matches one of the paths that we generate or generated in the past. The UNIX path isn't stored in config XML since libvirt-1.3.1.
