cannot launch xp vm on ubuntu-64bit 10.04

[spano]

i recently upgraded my ubuntu 64-bit to version 10.04.

when i attempt to launch my xp-64bit vm, the window pops up then disappears. status shows as 'aborted' in the vbox window. i was running vbox 3.1.6

i then attempted to try vbox 3.2 beta1 r60785. i still can't launch xp, but i get a popup with the following:

failed to open a session for this virtual machine win xp the vm session was aborted. details:
