QNX4 on Windows virtual PC?

Hi,

I’ve been following the posts about VMware here and there appears to be
quite some successes. But now someone at work told me that Windows also
seems to have a virtuall PC option. Moreover he claims that QNX4 runs on
it. Has anybody done this? And is the QNX4 support on it comparable to
that of VMware?

BTW: Suppose you have a virtual PC system (wheter VMware or the other one)
which runs a few instances of QNX4 on a FLEET LAN containing native QNX4
nodes and perhaps even other VPC systems running more QNX4 systems. If you
do a “sin net” would you see all of the instances appear on the output?

Thans for any info on this issue.

rick

never tried VPC, but with VMWare, FLEET works fine.

I run/code QNX4 on Virtual PC (6.0/1) on my Macintosh at home, and FLEET
works fine too.

Don’t know much about VirtualPC, but quick test I did with the eval version
showed
it was a tad faster then VMWare. But a friend of mine did more extensive
testing with
real world appliation and VMWare was definitely faster and much more
flexible.

With VMWare I know you can run many instances of QNX4 on the same machine
and they can all network together (along with some other QNX4 machine)

Curious: what does your netmap look like on a native QNX4 machine on the
LAN, then? You can’t map multiple nodes to one MAC address, can you? Or
perhaps the VMware machine runs it’s adapter in “promiscuous mode” and
handles packets destined for it’s internal pseudo MAC addresses?

Every virtual machine get its own MAC address, at one time I had 4 QNX VM
plus one Linux. I can understand how they can set he network card in
promiscuous mode and then listen to all packet, but what I don’t understand
is how they can transmit a packet and have the source address set to a
different MAC address then the real NIC. I guess it’s a feature NIC have
that I don’t know about :wink:

More use of VMMachine. When I grab a Windows utility that I want to try or
when I want to do some test that I beleive can corrupt the machine (adware,
spyware, etc) I run Windows inside VMWare. I keep a copy of the Virtual
partition which has only Windows install it in. Hence if there is a problem
I can come back to a “fresh install machine” in seconds, very nice.

All NIC’s I’ve seen take a fully formed packet on tx. ie the
ethernet header has to be filled in so you can specify whatever
ether src you want.

I see, thanks. For some reason I was under the impression the hardware was
taking care of that field.
