Hi, I used spaceinvader's Macinabox to install a VM on my Unraid server that runs MacOS 10.11 "El Capitan".  I installed using a Time Machine restoration to the OS vdisk.  That booted properly and ran correctly first time.  I performed a controlled shutdown and, using the Edit feature of the VM, changed memory from 4096MB to 8192MB.  Upon restarting the VM, the system fails to boot.  It flips back and forth between showing the Clover bootloader and the initial Apple logo.  No progress bar is displayed and control returns to Clover after a few seconds.  I attempted to restore the configuration back to 4096MB but the same problem occurs.  Can someone please help me to restore operation of this machine?

new problem

your loader and nvram files are wrong. they changed when you changed ram amounts. they should point to the files in the macinabox folder.

Understand.  But I guess I'll have to reinstall because I don't have a backup of the XML file to understand what the original files were called.

 

If I want to increase memory size of the VM without risking breakage like this, what is the best way to change the value?  Manual editing of the XML?  The default size is 4GB and I want 8GB.
