Hi. I'd like to experiment with host device passthrough in ovirt 3.6. I have a temperature sensor that connects up to a serial port. I've plugged the device into one of my virt hosts, and through /dev/ttyS1, I can read it. # dmesg | grep ttyS1 [ 1.140221] 00:04: ttyS1 at I/O 0x2f8 (irq = 3) is a 16550A ls -l /sys/class/tty/ttyS1/device/driver reveals: I don't necessarily see this device listed in the host passtshrough. In addition, since I'm able to connect to the serial device right now on the host, this would mean that I need to "blacklist" that device from the host so that when it boots, it doesn't load the driver? Thanks for any help..
