Gentoo USB serial passthrough KVM

I have a Conbee II Zigbee receiver. After a restart the USB passthrought stopped working (on the guest VM I always get errors like:

usb 2-2: new low-speed USB device number 25 using uhci_hcd
usb 2-2: Invalid ep0 maxpacket: 64 usb
usb2-port2: unable to enumerate USB device

So I decided, passthrough the USB serial. It’s a little tricky 🙂

    <serial type='dev'>
      <source path='/dev/ttyACM0'/>
      <target type='isa-serial' port='1'>
        <model name='isa-serial'/>
      </target>
    </serial>

The trick is the serial type because it is dev.

Glassfish start script

Hogy is kell, gentoo alatt glassfish szervert indító scriptet csinålni. Álljon alåbb a példa:
LĂ©trehozunk egy file-t /usr/local/bin/gf_start tartalma:

#!/bin/bash
/opt/glassfish/glassfish3/bin/asadmin start-domain

Kell egy stop is: /usr/local/bin/gf_stop tartalma:

#!/bin/bash
/opt/glassfish/glassfish3/bin/asadmin stop-domain

És maga az indító script /etc/init.d/glassfish aminek a tartalma:

#!/sbin/runscript

depend() {
        need net
}

start() {
        ebegin "Starting glassfish"
        # Ensure that we run from a readable working dir, and that we do not
        # lock filesystems when being run from such a location.
        cd /
        start-stop-daemon --start --quiet --background --make-pidfile --pidfile /var/run/glassfish.pid --exec /usr/local/bin/gf_start
        eend $?
}

stop() {
        ebegin "Stopping glassfish"
        /usr/local/bin/gf_stop
        eend $?
}

restart() {
        if ! service_stopped "NULL" ; then
                svc_stop || return "$?"
        fi
        svc_start
}
