I successfully installed El Capitan 10.11 on my MacBook Pro (running 10.10) inside of VirtualBox 5.0.8 r103449. Everything works pretty well and the performance is quite reasonable for a virtual machine.
One issue remaining is that my resolution is fixed at 1024x768. With my Windows and Linux guests, installing the VBox Guest Additions resolves this very easily.
The supplied VBOX Guest Additions ISO has guest installation utilites for Windows, Linux, Solaris, and OS2, but lacks guest additions for OSX. Does VirtualBox provide any guest additions for El Capitan guests (running on Mac hardware)? Or is this part of the roadmap at all?
Ultimately I'm trying to resolve my resolution issues, so if anyone has suggestions for that with El Capitan, please let me know.

There are no Guest Additions for any OS X guest, so you have basic VESA graphics only.
If you have any further questions then post a VM log file: with the VM fully shut down, right click and "Show Log" in the GUI, save "VBox.log" (ONLY) to a zip, and attach the zip here.

EFI provides two distinct video interfaces: GOP (Graphics Output Protocol) and UGA (Universal Graphics Adapter). Mac OS X uses GOP, while Linux tends to use UGA. VirtualBox provides a configuration option to control the framebuffer size for both interfaces.
To control GOP, use the following VBoxManage command:
VBoxManage setextradata "VM name" VBoxInternal2/EfiGopMode N
Where N can be one of 0,1,2,3,4,5 referring to the 640x480, 800x600, 1024x768, 1280x1024, 1440x900, 1920x1200 screen resolution respectively.

What about the resolution of 1920 x 1080? Can I change to this resolution?

No. Not unless you recompile VirtualBox from your own modified trunk.
