Is there any possibilities to limit disk IO for virtualization guest
I would like to know, if it is possible to limit IOps for jails, or
Bhyve guest, or VirtualBox quests. There are ways to limit CPU or
RAM for them, but CPU and RAM are really huge these days. On the
other hand, HDDs are still very IO limited and if one guest runs
disk IO hungy task, then all other guest are affected / slow.
I read about plugable GEOM scheduler few years ago (GEOM_SCHED), but
it seems that it is dead project and there is no module for it to
allow some scheduling according to PID, JID or something like this.
So do we have anything like this for Jails or Bhyve?

Well, there is rctl. I haven't tried it yet though.
As far as I know, it is just another way to limit CPU, memory, swap,
SysV semaphores, but no way to limit disk iops or bandwidth.
