Parallels Virtualization and Automation Software

RESOLUTION

To be able to add external devices inside VE please use vzdevctl command and do the following actions:

1. Make sure the device on port is working on Hardware node itslef.

2. Create legacy symbolic link, the most of software need this link to open and communicate with device on port (skip this step fro USB devices and go to point 3):

For serial ports

To obtain port name ( \DosDevices\COM1, \Device\Serial0) please run the following command:



replace indexes with correct ones (usually there is a simple mapping like Serial0->COM1, Serial1->COM2, etc).

For parallel ports

 
with same mapping rules.

3. In case of mapping of USB devices start from this step skipping step 2.

Create pnp shared device as described below, because some new soft requires interface instead of legacy link:

where : 

--deviceid – device system identification, which can be retrieved from Device Manager (Device Properties->Details->Device Instance Id) or by using of devtree command :



--alias – device alias (can be omitted, however it’s better to use one to avoid quite complicated deviceid usage ).

Other parameters

--connect – connect device to running VE right after adding this device to sytem (it’s impossible to connect device to stopped VE). If this parameter omitted , device won’t be connected, but can be connected later. If external device isn’t connected to HN it can be added and connected anyway , however it will be inactive while this device is physically connected to HN.

--onboot – device will be connected to VE automatically after VE start up , otherwise it will be necessary to use command connect manually. 

The command connect is used for connecting device to certain VE :



Please use the command dconnect for disconnection and remove for device removing as well. See more detailed description in utility help.
