5756	VirtualBox guest freezes while starting at 0% if serial ports are enabled => Fixed in SVN	Mike		"Running VirtualBox 3.1.0 r55467 on Ubuntu 9.10 (non-OSE) installed via apt from the virtualbox.org apt repository.

VM guest OS is Windows XP.

I was running the OSE in the Ubuntu repositories before, but found I would require USB support since virtualbox only supports 2 serial ports at a time.

Now, when starting my VM, if BOTH serial ports are enabled, the VM freezes at 0% while ""Starting virtual machine...""

My serial settings are:
Port 1
Enabled
COM1
Host Device
/dev/ttyS0

Port 2
Enabled
COM2
Host Device
/dev/ttyS1

It freezes up with any settings for the second serial device. I have verified that nothing is using the serial ports, and that they function from the host machine."	defect	closed	uart	VirtualBox 3.1.0	fixed	serial freeze startup		other	Linux
