Running "top" on a System with Multiple Virtual Machines

[darinpeterson]

Is it normal when running "top" from the command line to see the processes on ALL virtual servers?

The reason I ask is that I have multiple services of mysqld as well as other services that appear when running top.

If you are referring to the host system and are using OpenVZ/Virtuozzo or any other container virtualization technique (like LXC), then yes.

Thanks Falko...

On my base system I have installed 5 virtual containers on Squeeze using OpenVZ. One my web container I have nearly completed the installation of the web container.

For some reason there are 5 apache2 processes running under top. When killing them, they respawn. Do you believe there is a problem with this virtual container? Should there be 5 apache2 processes running?

I used the howto document here to install the web container: http://www.howtoforge.com/multiserve...th-ispconfig-3

Thank you for your time!

Please check the apache configuration (/etc/apache2/apache2.conf) - especially the StartServers, MinSpareServers, and MaxSpareServers settings.

Hi Falko, Here are the lines from my web server that runs under OpenVZ:
<IfModule mpm_prefork_module>
StartServers 5
MinSpareServers 5
MaxSpareServers 10
MaxClients 150
MaxRequestsPerChild 0
</IfModule>

I believe there is going to be a similar problem with mysqld when I'm finished configuring the server...
