VMM: VMs cannot start on Core iX CPUs

Description
AndyMutz cannot start his VMs.
Host: Vista, 32-bit, VBox 3.2.0, Core i5 CPUs
Disabling nested paging allowed his VMs to start. If so there seems to be a bad bug in new VMX code.

A log of a session with nested paging disabled (no other changes please!) would be useful too.

hello,
here are two new log files, one with nested paging off and one with NP on. while running with NP on, i turned the VM forcefully off after about 5 minutes, as there simply is nothing happening and the VM seems to hang indefinitely.

Same here! 3.1.8 worked fine, 3.2.0 hangs. If setting 1 CPU in the settings, the guest boots, but it is VERY slow. 2+ CPUs - hangs.
CPU - Core I5, Host - Windows 7 x64, Guest - Windows XP or Ubuntu 10.04.

Same issue on i3-530 under Win7-64b host - all guests work fine with 3.1.8, all hang with 3.2.0 if NP enabled but work if NP disabled

Having the same problem. VMs start fine on 3.1.8 and 3.1.6 WinXP and Ubuntu guests will not start on 3.2.0
Host is 64 bit Ubuntu 10.04 kernel 2.6.32-22 on Core i5 M430
