Could not access KVM kernel module

wallgeek opened this issue 7 years ago · comments

Getting error "Could not access KVM kernel module. NodeOS will be slower without it" in "npm start" command.

My system does not support KVM. Is there any way to proceed further without it?

You could be able to pass the --disable-kvm flag to QEmu, or also send a pull-request with a better autodetection mechanism. El 25/3/2017 23:41, "Abhishek Khare" <notifications@github.com> escribió:

I exactly had no idea how to pass --disable-kvm flag to qemu. So I tried npm start --disable-kvm but didn't work. I tried npm run build --disable-kvm but didn't work too. So I read your this link https://github.com/NodeOS/NodeOS/blob/master/scripts/start#L34 and commented out the line but didn't work.

So after scanning the script file I commented out "-enable-kvm" from args array and also commented out "args.shift()" from "if(kvm.test(contents) === false)" and now it is working fine.

I'm happy to know you were able to fix it :-)

Just curious, why are you using NodeOS for?

I have been working with Nodejs a lot these days and when I read about NodeOS, I got excited and was curious to know more about it.

I wanted to try it out and learn more about its capabilities but couldn't find proper documentation. So whatever I am getting, I am trying to figure it out as much as I can and would love to contribute, if possible, in future.

Of course it's possible :-D So far, if you find difficult to follow the documentation you could be able to send us the corrections and clarifications that you'll find, in fact documentation is an area where we need some big help here :-D Would you want to work on that? :-)

Sure, I would like to work on that. :)
