docker-android under VM has slow performance about docker-android

[fernandoravagnani-luizalabs]

@butomo1989 here was the steps to enable the virtualization in the VM:

• first we upgraded the VM's virtual machine hardware, from version 8 to version 10

• after that, we enabled the hardware virtualization support on the VM

• finaly we checked the Expose hardware assisted virtualization to the guest OS. After this checked option, we were able to use the kvm feature on the OS

ps: using hardware or software CPU and MMU was praticaly the same performance

Hi @butomo1989,

I realized that it was not so clear in the issue, but it's a VM running on a physical machine with VMWare ESXI 5.5, Hardware acceleration enabled on bios and Nested Virtualization provided.
It can be easily verified with a ubuntu packet called cpu-checker that u can install with:

apt-get install cpu-checker

Once it's installed, we can check the Kvm status with the command:

kvm-ok

It would tell us if this environment is ready to virtualization with hardware acceleration, like shown below:

There's no any parallel process running, this ubuntu is exclusively for this device virtualization and the numbers with two devices with and without stress.

Without stress:

With stress (intense interaction with Google Maps):

What about Vagrant? Then the setup could be automated as well (don't have experience with it though).

Hi @alanbueno ,

Thank you for reporting this issue. as I understand that you are using VMWare to simulate linux OS, could you provide me guideline or step how you enable hardware virtualisation in that VM to be able to use x86 image (of course you can create PR for it)? because as far as I remember VM do not support hardware virtualisation (see #11 ).

In my linux computer 1 docker-container of docker-android consume 1 GB RAM, but the usage of RAM will get bigger when you start play with it and also depends on your application. e.g. hello world android application in emulator should consume less memory than any other bigger application like google map. Could you run top in your command line in your linux machine and see how many memory do you need for docker-android and how many free memory do you have? and is there any other parallel process running in that VMWare?

Hi,

@alanbueno Honestly I never try to run x86 docker-android image under VM. I just created gitter and could you join there: https://gitter.im/butomo1989/docker-android ? I might need additional informations so I can help you.

@fernandoravagnani-luizalabs Cool! Last time I tried with VM from virtualbox that was created by docker-machine and it didn't work. I will try again to create VM by myself. but I am really glad that it works with other VM like ESXi although there is performance issue. Thank you for the guideline!

@fernandoravagnani-luizalabs It would be great if you can put that information somehow in README.md and create PR.

I tried following cases:
Host OS: OSX; Virtualbox: Ubuntu 16.04; Status: failed (x86 cannot be run under that VM)
Host OS: Ubuntu 16:04; Virtualbox: Ubuntu 16.04; Status: failed (x86 cannot be run under that VM)

It seems Virtualbox has issue with nested virtualisation.

• https://gns3.com/discussions/gns3-vm-your-cpu-does-not-suppor

and the solution is by using VMWare.

I will try to run under VMWare player and will provide the docs in the end. Regarding vagrant I might just create ticket and mark as "help wanted". Maybe someone who has experience with vagrant can investigate it. @andrcuns
