Black screen - trying to install Mavericks - El Cap Host

[loopy]

I am trying to set up a VM running Mavericks ( needed to test some software)
I have Virtual Box 5.0.22 , running on El Cap 10.11.5, iMac (Retina 5K, 27-inch, Late 2014)
I created a VM using "OS X Mavericks 64-bit" - accepting all defaults.
I followed the procedure for creating a bootable .dmg from the "Install Mavericks.app"
When I run the VM , I get is a black screen that resizes a couple of times, nothing more. It never proceeds past this point. It actually doesn't matter if I attach the .DMG to the "optical drive" or leave it empty.

PS Other VM's ( e.g. Ubuntu) run fine.

Log file attached

I see a lot of errors in the log, related to RAM. It's like VirtualBox doesn't believe the RAM is real/physical.

I see that VirtualBox 5.0.24 came out today, with fixes for IO APIC bugs. I guess it would do no harm to try it.

I followed the procedure for creating a bootable .dmg from the "Install Mavericks.app"

00:00:01.063276 File system of '/Users/andrewc/Downloads/mavericks.iso' (DVD) is hfs

What is the procedure that you followed?

00:00:01.098113   RamSize                 <integer> = 0x0000000200000000 (8 589 934 592, 8 GB)

Decrease that to 2 GB. For now.

00:00:01.098267   VRamSize         <integer> = 0x0000000001000000 (16 777 216, 16 MB)

Increase that to at least 32 MB.

I followed the procedure
sudo iesd -i /Users/andrewc/Downloads/Install\ OS\ X\ Mavericks.app -o Mavericks.dmg -t BaseSystem

Then set Mavericks.dmg as the startup.
I had also tried creating a Mavericks.iso

Anyway, I solved the problem by the roundabout way of creating a virtual machine on a MacBook Pro - no problems there - then copying the VM to the iMac

You must have either changed the way that you installed the VM, or the recipe of the VM itself. Otherwise it does not compute. Glad you got it working finally.
