Feb 28, 2018 - Proxmox Serial Port Pass Through Windows In Kitchen. Qemu USB passthrough (windows. Br0 -vga qxl -spice port=5930,disable-ticketing. I have a problem with port forwarding when I create VMs. I have problem on guest vm proxmox with windows 7.1 OS, i add 4 serial port, but why read in guest.

We are using Linux + KVM + Qemu with libvirt on our servers to manage virtual WIndows 2008 Servers. The Host is Ubuntu 11.04. The point is on one of our Windows server 2008 guest, we need to connect a dial-up modem. After connecting the modem to the Host, we found that it was connected to /dev/ttyS0. We did checked that the modem was recognized using echo atdt3333333 > /dev/ttyS1 Server.xml configuration contains Now, launching our virtual server, Windows doesn't see any COM port at all, and therefore doesn't see the modem ( all sort of virsh define / stop / start.

Had been done ) Does anyone know how to achieve this?
