Regarding Virtual Machine kernel mode debugging

Perhaps not the prime place to air this request but the response of this
community will be invaluable in assessing its usefulness.

Virtual Machine producers and the owner of the KdDbg stub drivers in
Windows:

Please consider a ‘standard’ transport for KDBG between VMs and the
hypervisor / primary (host) environment that is not so brain-dead as polling
a virtualized serial port warped through a host pipe that can’t seem to
perform any better than a real serial port.

We got FireWire in the physical world (if you can get it to work) and now a
(very expensive) USB-dongle-USB solution. But heck, lots of decent KDBG is
done in VMs and it would sure be useful to have a *high performance* *high
reliability* solution to this very common scenario.

As the Bartles & James adds used to say, “Thanks for your support.”

I understand your complaint. My management has been very sensitive lately
about discussions of upcoming products. So I’ll just say at the moment that
I understand your complaint.

Ditto; I do a lot of development in VMs of hardware-less networking
components.
