Hello,
I am trying to understand the VIRT field that shows in the TOP command output. I have a users application that appears to be leaking memory. I see that the field VIRT in the top output is showing 55.8g.
The question is where is that getting stored? The disk does not appear to have that much space used on it. An the system only has 24GB of ram. Is this a combination of RAM and DISK? Here is some examples.
Hi,
First of all I appreciate this group very much for its informative discussions and posts.
Here is my question.
I have one process whose virtual memory size increases linearly from 6MB to 12MB in 20 minutes. Does that mean my process has memory leaks?

So, I would ask you a piece of advice about which books or titles could give me comprehensive information about virtual memory in UNIX. Especially, I would found out that virtual address translation corresponds structures of kernel!

virt-login-shell
VIRT-LOGIN-SHELL(1) Virtualization Support VIRT-LOGIN-SHELL(1)NAME
virt-login-shell - tool to execute a shell within a container matching the users name
SYNOPSIS
virt-login-shell
DESCRIPTION
The virt-login-shell program is a setuid shell that is used to join an LXC container that matches the user's name. If the container is not
running, virt-login-shell will attempt to start the container. virt-sandbox-shell is not allowed to be run by root. Normal users will get
added to a container that matches their username, if it exists, and they are configured in /etc/libvirt/virt-login-shell.conf.
The basic structure of most virt-login-shell usage is:
virt-login-shell
OPTIONS -h, --help
Display command line help usage then exit.
-V, --version
Display version information then exit.
CONFIG
By default, virt-login-shell will execute the /bin/sh program for the user. You can modify this behaviour by defining the shell variable
in /etc/libvirt/virt-login-shell.conf.
eg. shell = [ "/bin/ksh", "--login"]
By default no users are allowed to use virt-login-shell, if you want to allow certain users to use virt-login-shell, you need to modify the
allowed_users variable in /etc/libvirt/virt-login-shell.conf.
eg. allowed_users = [ "tom", "dick", "harry" ]
