vzeventd(8)

📦 version 4.9.4, in ubuntu jammy

✨ vzeventd — the OpenVZ events daemon ✨

okay so bestie, welcome to vzeventd(8) from the Containers section 💅 this is the little daemon that just gets things done whenever the OpenVZ kernel has something to say. she's giving backstage crew energy — you never see her, but the whole show falls apart without her 🎀

🌸 SYNOPSIS 🌸

vzeventd [-v] [-d]

vzeventd -h

🦋 DESCRIPTION 🦋

So basically, this daemon is the designated listener 👂 she takes care of events sent over by the OpenVZ kernel (via a netlink socket, iykyk) and then does the required actions for those events by running specific scripts. Every single event she receives comes with two things: an event name and a container ID. that's it, that's the whole message 🫶

For every known event, the event script

/usr/lib/vzctl/vzctl/scripts/vzevent-event_name

gets executed, and the container ID is passed into that script as the VEID environment variable. Periodt. 💖

  • Event scripts that don't exist? ignored. not her problem 🙈
  • Unknown events? also ignored — but logged, because she's not gonna let that slide silently 👑

The following events are recognized:

  • start
  • stop
  • mount
  • umount
  • reboot

and the following event scripts are provided, bestie:

  • vzevent-stop — takes care of removing ARP and routing records for the given CT from CT0. cleaning up the receipts, literally ✨
  • vzevent-reboot — takes care of rebooting a given CT. the main character move 🔥

💅 OPTIONS 💅

  • -v — increase verbosity. and yes, you can use it multiple times — stack it like jewelry, go off 💖
  • -d — debug mode. she does not daemonize, she runs in the foreground so you can watch her work. very voyeuristic of you 🍓
  • -h — display help and exit. the classic "just tell me what you do" button 🌸

⭐ EXIT STATUS ⭐

Returns 0 upon success. that's it. she succeeded. slay 💅✨
