Linux Vserver, terrabytes of network traffic, or ifconfig garbeld?

I have my own little monitoring script, and I have added a few nodes to it, two of which are Linux Vserver based. Rest is OpenVZ or KVM. Now those two nodes have been up for 2 days, and my monitoring script tells me that the network interface has used hundreds of gigabytes:

|---[remy][vps12][~]

          inet addr:127.0.0.1  Bcast:0.0.0.0  Mask:255.255.255.255

          RX bytes:60834318358 (56.6 GiB)  TX bytes:60834318358 (56.6 GiB)

And the other one:

|---[remy][vps13][~]

eth0      Link encap:Ethernet
          inet addr:127.0.0.1  Bcast:0.0.0.0  Mask:255.255.255.255

          Interrupt:30 Memory:f4000000-f4012800 

lo        Link encap:Local Loopback

          RX bytes:85762275126 (79.8 GiB)  TX bytes:85762275126 (79.8 GiB)

Compare that with one of the OpenVZ nodes:

Is this a Linux Vserver specific thing or is there something else wrong?

  • It's a vserver thing. You see stats for all traffic on the node.

  • vserver as in OVZ?

  • @Jack said: vserver as in OVZ?

    No, vserver as in linux-vserver.

  • @sleddog thanks. That I find quite shitty, do you know why it has been done that way?

  • So it does not need to run through tr/iptables and slow the network speed down or create load.

  • For vserver explanation, maybe William is the best :D

    Yeah i don't think there is anyone that still uses vserver except for Edis and Alvotech :D

    Understand that, still don't like it for my own monitoring. Those two nodes are at Edis indeed.

    @William why does edis uses Vserver? LXC for example is included in mainline kernel. Except for that Vserver is grownin in the software stack, if you could today start again, would you still choose for Vserver?

    A bad choice when we started with it, can't change anymore :) And no, we would likely use OpenVZ (But not with Solus, as we are based on Debian and not CentOS)

    Why was it a bad choice? And, why did you start to use it?

  • Because it has more issues than advantages, no working IPv6 for example. Someone else picked it.

    @Raymii said: Why was it a bad choice

    Because it SUCKS MAJOR ASS - No proper (full-featured) TUN/TAP device - No IPv6 in the stable version - No per-VPS counters of traffic in ifconfig (as you noticed) -- can't use vnstat - No iptables support in the VPS (!!!) -- have to use some weird host-specific firewall web-panel - Even "mtr" does not work! Vserver is such a complete joke, it's not even funny. Run as far as you can from it, even OpenVZ is worlds better than Vserver. And of course with EDIS you can choose to buy KVM instead.

  • @rm_ said - No proper (full-featured) TUN/TAP device - No IPv6 in the stable version

    These are limitations of the technology. If you need them then it's important, if you don't then it's irrelevant. OVZ has limitations too. For example it doesn't support ip broadcast (with venet). So you can't run a samba master or a dhcp server. But if you don't need that feature then it's irrelevant.

    • No per-VPS counters of traffic in ifconfig (as you noticed) -- can't use vnstat

    You also can't monitor the load of your VPS, as the load averages are those of the host node. On the other hand, vserver is the only virtualization technology that lets you monitor the host node's load from within the VPS :)

    • No iptables support in the VPS (!!!) -- have to use some weird host-specific firewall web-panel

    Which is easy to use and works fine. If you want a reactive firewall app on the VPS it's not going to work, but again, not everyone needs or wants that.

    I bought a vserver from Edis a couple months back from a offer here. Less then $1/month. Been using it experimentally for web/mail/dns hosting, so those missing features don't matter for me. The load & transfer reporting is weird but I've gotten used to it.

    During those two months the vserver has:

    • Been up continuous, no hardware downtime at all and only some very, very minor network blips.
    • Performed extremely well, continuously. No 'laggy' times of day, no bad days versus good days.

    I've come to accept the Edis vserver for what it is -- something different that's damned reliable. I like it :)

    @sleddog said: Which is easy to use and works fine. If you want a reactive firewall app on the VPS

    I have my own firewall script uniform across all my VPSes (uploaded and updated automatically with some other scripts, only .conf changes a bit), why would I want to bother with some web-based firewall specifically on one particular host? And as I said the web firewall is host-specific, e.g. I only used Alvotech's, and it kind of sucked. Also while they were nice enough to patch in (experimental?) IPv6, there was no IPv6 support in the firewall. So while Alvotech similarly to your experience with EDIS was quite reliable and cheap, Vserver was so limiting and annoying, that I ended up cancelling it.

  • @rm_ said: And of course with EDIS you can choose to buy KVM instead.

    For my own hosting and virtualization needs proxmox and vagrant are good enough. And, I have both vserver and KVM over at Edis, and they work fine for what I do with them (lighttpd cluster). Just my monitoring on the Vserver nodes is messed up (http://vps11.sparklingclouds.nl/status/ vps12 and vps13.)

    And for the firewalling, I can see how that is an issue. I only use firewall (iptables) on openVZ nodes, have not tried this yet. The Edis panel for firewalling is quite good...
