Hi.
I am recently installed virtual pc 2007 and did some test with mikrotik.
From what i have found virtual pc allows you to have up to four virtual network adapters and the can be bound to a physical network adapters.
I made an install for mikrotik on a virtual machine and everything worked with no complications ( just like the real thing ). I did saw some post regarding vmware and that it wouldnt be 100% operational.
But it seems that all works fine with no problem in virtual pc 2007 case.
So can somebody predict or think of any complication that might occour?
Along with automation that can be done with virtual pc i see no reason for mikrotik to be an really good solution running on windows 
Oleg,
What things are you hoping to accomplish with Virtual PC?

Nothing special really
Just to have a possibility of deploying a dedicated router on windows pc without need of dedicated hardware You never know when you might need something like that.
Running this scenario for months now w WinXP SP2 az a host on a Intel P III 1000MHz 512SDRAM w VMWare. I use the host WinXP SP2 for a dedicated download machine + smb server. No problems whatsoever except maybe just a little more latency (or less latency) no real way to tell.
I have noticed before on the non-virtual Mikrotik, that when I open a webpage I must wait a second or two before anything shows on the browser where if the connection woudl be direct to the WinXP there would be no such delay. Maybe this is caused by the PPPoE tunneling ???
vmware was first choice as it is free and very good emulator, imo - virtualPC 2007 is not free at all 
it’s not free?
you should look into things a little bit before posting things you do not know about.
ok, whatever, it is not available for linux anyway, so i do not care. i would go Xen rather than any M$ product 
but you should use emu you trust and know how it operates, so it is only your preference what you use or are willing to use
