Xen and serial ports access from domU

Howto use the serial ports (/dev/ttySX) from a xen domU

I've recently migrated a zabbix server from a standalone machine to a xen vm.
Attached to serial port of the old server there was a GSM modem used by smstools to send via SMS some of zabbix alarms.
So I wanted to use the same modem with the new domU zabbix server: this is my little howto to get a xen domU access serial ports.

  1. First of all we have to avoid the dom0 to access the serial ports of the machine:
    with debian create a new file (eg.serial-blacklist) in /etc/modprobe.d/ specifying the blacklisting for 3 kernel modules related to serial ports
    blacklist 8250
    blacklist 8250_pnp
    blacklist serial_core
  2. Configure the vm: in the configuration file for the domU specify the following lines:
    irq = [4]
    ioports = ['3f8-3ff']
  3. On the domU filesystem verify the availability of the kernel modules in /lib/modules/`uname -r`/kernel/drivers/serial:
    8250.ko  8250_pci.ko  8250_pnp.ko  jsm  serial_core.ko  serial_cs.ko
  4. In order to have the correct devices in /dev directory install udev:
    apt-get install udev
