7052	VBox causes host VGA/SVGA application segfault when the application does VGA port IO -> fixed in SVN/3.2.6	wzis		"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."	defect	closed	host support	VirtualBox 3.2.4	fixed			other	Linux
