Re: [Users] OS/app in the OpenVZ container

[Stoyan Stoyanov]

If thats right you just need to isolate the application process/ 
processes ? So may be the best way is just chroot it in the standard  
linux way. of course u can set limits too, but i don't thing it's  
possible in os-virtualization level to run  only application?

Yes, it's possible to run a single app in a container.
The easiest way is to let the startup scripts setup /proc, /sysfs  
and the rest of environment and then specify in inittab or rc.X what  
to run on this particular runlevel.

However, for media player you may also need to run some of X parts,  
not just a media player alone.

Thanks,

Hi All,

I'm doing some research on processing virtual machine recently.

As I what know now, I think OpenVZ vps runs the same OS kernel as  
the host system.
The vps is a group of processes which are forked on the host system.
In the OpenVZ container, thera are some processes to run an os.
Is it possible to run only one App in the container instead of the  
os based on the host os? such as a media player?
what are work should I need to do mainly?
could you give me some suggestion?

Thanks.

Tommy

hello,

I think I didn't describe my question clearly

If I want to start an app in the container, i should do the  
following step:
    1.create a container ,start it and there is an Guest OS running  
in the container now;
    2.enter the container and start the app I want;

it acts as a system virtual machine

what i want to do is :
    1.create the container
    2.start the app in the container

this will act as a process virtual machine

any suggestion?

thanks
