Here is how I setup my VM.

Base Memory: 392MB
Video Memory: 32MB
IDE Primary Master (CD/DVD): (latest plan9 iso was mounted here )
IDE Primary Slave: Plan9.vdi(Normal, 2.00GB)
Host Driver: CoreAudio
Controller: ICH AC97
Adapter 1:
Intel PRO/1000 MT Desktop (NAT)

--samd


I had to up the video memory for the VM to 32MB.
