How to know how much neighbours you've got in your OpenVZ VPS

FredQc

Have you ever wonder how much containers are running on the VPS node you're at ? There is a little trick I found while browsing Reddit:

grep devices /proc/cgroups

This should returns something like this:

devices 1 20 1

20 is the number of neighbours you have

Be advised that this works only with recent OpenVZ kernels and a patch have already been provided to "mask" this information to the end-user. Because it's providers little secret, you know ?

If you get "1" as the second number, the patch has been applied on the node. If you see nothing, your provider run an ancient Kernel.

So, I tried this little trick on my VPSes that use OpenVZ:

ImpactVPS $7 bundle devices 1 93 1

ReliableHostingServices $2 VPS devices 3 71 1

TacVPS (GVH) $7 VPS devices 4 22 1

ZXPlay 800GB HDD Special devices 4 15 1

My other VPS shows 1 or nothing.

Please read the OP...

Any hosters here wish to fix this. KernelCare hasn't patched this very well. You will have to install and manually reboot.

I noticed after my comment only for old kernel.
My kernel is always up to date

BoltVM: devices 3 113 1 - Amazing performance from an E3-1240 with 32G max.

Nothing on VPSDime or Crissic.
Patched on a new BoltVM node, XVMLabs.

I get nothing back on Wable. Guess the kernel is outdated.
