basically, 1 service/daemon for each container. The back-end DB would run in another "container". For example, running apache with a php web-app would be ideal for a container. In large-scale deployments, containers are used to run 1 application/server and nothing else. Use google to learn about "linux containers." I use containers daily as a way to segment off 1 program from all the others in a way that they cannot do any harm to the main OS.

explains more.Ĭontainers are a completely different thing that looks like virtualization, but it isn't. that means you can only use a 32-bit hostOS with virtualbox to do virtualization AND that only 32-bit guestOSes are possible. As we have set virt to No Virtualisation at the beginning, no matches will print No Virtualisation.If that command doesn't return anything, then your CPU doesn't support VT-x or AMD-v. A match will signified by the RSTART variable not being 0 and so we check this to find the type of virtualisatiion being utilised. When searching for lines beginning with flag, we search for strings svn or vmx using awk's match function.

At the end, print the data in the required format using the variables created. Using /proc/cpuinfo and free -mh along with awk, search for the strings required, using : as the field delimited, set variables accordingly, splitting the output of free -mh further into an array called arr based on " " as the delimiter.

I would like to also combine this info with that of /proc/meminfo or free -mh, so: "AMD Athlon(tm) II Neo N36L Dual-Core Processor, 1300 MHz, 2 cores, 4.7 GB Memory (1.8 GB Free), SVM-Virtualization" with the below output, this would look like (with "1300.000" rounded to "1300") "AMD Athlon(tm) II Neo N36L Dual-Core Processor, 1300 MHz, 2 cores, VMX-Virtualization" (or "SVM-Virtualization" or "No Virtualization") I would like to extract something like the following on a single line:, MHz, cores, Į.g.

Proc cpuinfo virtualization how to#

I know that this sort of thing can often be a very simple trick for sed/awk experts (I don't know how to approach this

Proc cpuinfo virtualization install#

I would like to pluck info from /proc/cpuinfo and /proc/meminfo (or free -m -h) "why not just ' yum install some-great-tool'?" is not ideal as all of this information is freely available to us right in /proc.

Proc cpuinfo virtualization portable#

The problem that I'm trying to solve is to produce portable output that I can display on all of the servers in our environment to show basic info at login using generic information on all CentOS / Red Hat systems.
