Remix OS with VirtualBox

https://groups.google.com/forum/#!msg/remix-os-for-pc/NB6GJdAHUsA/Aw4pQgpUAQAJ

First you have to install it:

• First off make your VM and make a hard disk for it. I recommend a Dynamic VDI of at least 10GB.
• Now you need to format and partition the hard disk. I just used a Lubuntu LiveCD that included GParted to do this.
• Format the drive EXT4
• Now mount the RemixOS ISO and boot into it.
  
• On it's boot menu, quickly press [Tab]
• Modify the boot command so it says
  /kernal initrd=/initrd.img root=/dev/ram0androidboot.hardware=remix_x86_64 androidboot.selinux=permissive INSTALL=1 DEBUG=
  
• Press [Enter]
• You'll see a scroll of output and then you'll reach the install screen.
  
• Select the partition you made
• Do Not Format
• Install GRUB = YES
• Install EFI GRUB = SKIP!!!!!!!
• It'll now installed

Now you have it installed, but booting it is another matter. By default it won't boot properly. The only solution I've found so far is to run it in VGA mode from GRUB.

The quick and dirty method is to

• Find the resolution you want from the 'Color Depth 16' codes on this table. And copy down the code.
• Boot into the VM
• Press [E] on the Boot menu
• Press [E] again
• Now add "vga=" to the end plus the code you picked. So for example, the end result would be "vga=794" for 1280x1024.
• Now press [Enter], then press [B]

The VM should now boot into RemixOS. Please Note the initial boot of Android always takes a while, up to several minutes.

Obviously doing this every time is a pain. So you can modify the GRUB menu.lst file to make it permanent. To do this I just booted my Lubuntu LiveCD again, mounted the partition and then opened './grub/menu.lst' using a Root level Text Editor. ex: "sudo leafpad /media/lubuntu/Androidx86/grub/menu.lst". Just add the "vga=XXX" to the first kernal listing and save it before rebooting.

However, even after all this and getting to the Desktop, it's really unstable for some reason. I still haven't figured out why when the Guest mode from the ISO runs relatively okay. Maybe I'm missing some boot commands. I'll keep playing with it.

Also, interestingly Google Apps are installed as well, but most things crash. Most likely Installation isn't ready yet, which is why the option is missing.

PS: You can get a few more specific resolutions, but it's complicated and I'm out of time. You can learn about how here:http://stackoverflow.com/a/8273560
