Hello again :)

How can I eliminate these services? I don't have free RAM on one of my VPS.

    Their kernel tasks, so their needed.

    I actually sorta prefer Mach's way of doing it, which is just to bundle everything to kernel_task.

    oh... it is like my other VPS? Because look at this:

    BuyVM:

    free -m
             total       used       free     shared    buffers     cached
Mem:           256         15        240          0          0          0
-/+ buffers/cache:         15        240
Swap:            0          0          0

 ps ax
  PID TTY      STAT   TIME COMMAND
    1 ?        Ss     0:00 init [3]
 1855 ?        Ss     0:00 syslogd -m 0

29801 pts/0    Ss     0:00 -bash
29820 pts/0    R+     0:00 ps ax

    And this VPS I am talking about:

    free -m
             total       used       free     shared    buffers     cached
Mem:           128        110         17          0          9         80
-/+ buffers/cache:         20        107
Swap:          509          1        508

    Do the types of virtualization differ on the said servers?

  • netomxnetomx Moderator, Veteran

    They are OpenVZ

    In KVM and Xen, Linux likes to cache ram. As you can see from your free -m you are only using 20 mb of ram as the real amount of ram being used is the one before caches and buffers. Hope that helps ;)

    So, my VPS from prometeus, is Xen? I thought it was OpenVZ.

    In OpenVZ, you don't see any of them processes because you don't have your own kernel. Whereas in Xen/KVM you do have your own kernel so you see and manage them.

    You should ignore them, their usually harmless.

    Either Xen, KVM or OpenVZ with vSwap (vswap likes to cache ram too).
