#7052 fixed VBox causes host VGA/SVGA application segfault when the application does VGA port IO -> fixed in SVN/3.2.6 wzis
Description

I have a Chinese/Japanese/Korean console terminal emulator which runs on Linux console virtual screens. The application will do VGA port in/out for displaying the CJK characters. The application ran fine before any VM in VBox starts. What I found is, once a VM in Vbox starts, ioperm call can still succeed, but any port_in/port_out to VGA ports (e.g. CRT_I/D, SEQ_I/D) on the Linux host (not Linux VM) will segfault. The issue remains even after all VM stopped and VBox processes exited. In other words: Only reboot of the host can fix the issue. I've tested with VMware server, and found no issue with VMWare. So, confirm this is a VBox compatibility issue.

#7028 duplicate Mac OS X 10.6 Server Host & Mac OS X 10.6 Server Guest - Limited to 2GB RAM wyrdR
Description

Cannot assign more than 2GB RAM to Mac OS X Server guest.

Host is new Xserve Mac OS X Server 10.6 (64 bit) with 12GB physical RAM available.

N.B. Trying to start VM with Mac OS X Server (64 bit) selected fails – see also related ticket:

why 2GB is the max size of memory for VM using EFI?
