I am practically exhausted. I have this rtclock_init panic problem and I saw most of it solve by adding bussratio="multiplier". But where actually do u change that in virtualbox? As in which option give u the ability to insert those code in VB?
I know this in an old thread but I had this problem with the latest VirtualBox.
I corrected this boot/install error by VirtualBox -> Settings -> System -> Chipset (Was set to IH9 or something, selected PIIX3)
This is Virtualbox 4+
Actually that's not correct! busratio=16 worked
But I have a problem after it installs and restarts I get FATAL: No bootable medium found System Halted.
If I don't remove the cdrom drive it says System config file /com.apple.Boot.plist was not found
