I have set open files for all users on a dedicated server A in /etc/security/limits.conf like below:



* hard nofile 1048576
* soft nofile 983040


And in /etc/pam.d/common-session I have loaded limits module like below:



session required pam_limits.so


I restarted server A and checking ulimit -Sn (soft limits) and ulimit -Hn (hard limits) displays the newly set values.



Now I have another dedicated server B in which I have 3 KVM machines. On the dedicated server B itself I have set open file as above and it works like a charm after a reboot. The same procedure for server's VMs fails and it shows default open files.



NOTE: They all have Debian OS



Is there something here I'm missing? Is it related to VMs at all? How should I set open files for VMs?
