[libvirt] limit pps via bandwidth
by Vasiliy Tolstov 16 May '17

16 May '17

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... What do you think? -- Vasiliy Tolstov, e-mail: v.tolstov(a)selfip.ru

[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.
