Hi all,
Here at my work we develop our code for an embedded system in linux, but
the application we use to put firmware onto the physical device runs
only under windows. I am investigating the feasibility of running
windows as a virtual machine, rather than our current situation where
every developer has two boxes at their desk. The new boxes at work
don't come with a serial port, so I am trying with a USB to serial
converter and running kvm like:
kvm -hda windows2.img -boot c -m 1000 -serial /dev/ttyUSB0 -smp 2 -usb
-usbdevice "tablet" -full-screen -cdrom /dev/cdrom
I can do low-cpu tasks with the embedded device like reading the current
configuration, but I can't do cpu-intensive tasks like loading a new
firmware onto the device. I have sniffed the line to see what is being
sent down the physical wires and I have logged inside windows what the
application was sending and the two are almost the same, until we meet
an ascii null. We log an ascii null (0x00) as being sent, but on the
other side of the virtual machine 0xFF is coming out. We can run the
application with Wine and download firmware but can't read the current
configuration, so it's not the linux usb to serial converter drivers.
So my question is, do you have any idea what's going wrong?
I have tried kvm72 and the 2008-08-12 nightly snapshot.
I am running an Intel(R) Core(TM)2 Duo CPU E6550 @ 2.33GHz with
2048MB RAM on Ubuntu Linux 8.04 (Hardy Heron).
if anyone can help, it would be greatly appreciated!
Thanks in advance,
Michael Malone
