Made the same experience: I was using 2 VMs created some time ago under VBox 3.0.4. Upgraded from 3.1.8 to 3.2.0 and manually ran "/etc/init.d/vboxdrv setup" to rebuild the kernel modules. Both VMs are Windows XP SP3 32bit and run fine (unmodified) under 3.2.0. When I enable Page Fusion on both VMs, the first VM runs fine but 30 seconds after starting the second VM, the first and some times also the second VM locks up.
"VBoxManage controlvm VMNAME poweroff" also hangs but "kill PID" (PID=process ID of the hanging VBoxHeadless process) stops the VMs in a way that they can be reconfigured/restarted (no need to reboot host).
Host system has an Intel Q9400 (Quad) with 8GB RAM running Ubuntu Jaunty (9.04 amd64) and I'm using VBoxHeadless to start the machines. ACPI, IOAPIC, VT-x, VTX-VPID and nested paging are enabled, PAE and large pages are disabled.
Any ideas on what I'm doing wrong here?
