Thanks for bothering with our exotic problem! Hello, even this is a few Months old. I got a similar issue but i didnt even tried to use a passtrough PCI device. My instinct told me that this might be a long frustating night and it looks like i was right :) Anyway we got a ISDN USB Modem also a Fritz which can be passtrough to the Guest but guess what - the guest instantly turn off - complete segfault not even a BSOD Its also a win 2003 and has already the Fritz drivers (its a p2v) So i came to 2 possible solutions both iam not very shure about. 1. buy a ISDN Serial modem and passtrough the serial port - which should be fine. 2. get somewho the usb box running on the host - map it to an tty and run it from there. My concernc specially for method 2 is that isdn riginig in problem on ttys but i think its worth a try just to find out if its posisble to get the usb box running on the host :) anyway serial ISDN modems shoul dbe fine also for your application serial is serial - so it shoul dbe supported by any fax solution in that universe and even in some others in germany thers only one manufacturer i know of producing that stuff - its devolo having such a piece but heavy pricy - cheapest is 130€ up to 200€ compared to pci cards for 20 bucks a bit oveprices but hey if it works :) anyway - well usb and pci passtrough support in KVM is not so much supported as vmware supports it - i know it sucks a bit but actually it does make sense. you put the server in a 19" rack to protect it form heat, cleaning personell and even lightning, you buy a usv for several hundreds to protect it against powersprice and failure and then you put in a usb or pci modem - one lightning into your PABS (phonesystem) and your well protected server isnt worth the metall its made off from my point of view - networkcards and raidcontroller are the only pci(e) devices in a server - usb only a keyboard, a mouse and in emergencys a usb drive managed by the amdin himself - for eveything else theres a network device (phone, fax, coffeemachine, whatever) of course doenst help us by our problem but at least there are some real arguments against pheriphere devices in a server -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
