Thanks, --hostiocache on works and machine proceeds further.

Next try:

!!Assertion Failed!!
Expression: pDev->enmState == VUSB_DEVICE_STATE_RESET
Location  : 
void vusbDevResetDone(VUSBDEV*, int, void (*)(VUSBIDEVICE*, int, void*), 
Trace/BPT trap (core dumped)

Same machine as in part one, Windows 7 Beta x64 (this matters! - x32 works).

Steps to produce:

Some time after reboot and installation of VB guest tools machine gets 
100% CPU.

VBoxManage controlvm test reset

Machine tries to boot, but waits forever on the flashing flag logo.

VBoxManage controlvm test reset

And we have a coredump.

Sphinx of black quartz judge my vow.
