Previously, I’ve never had much success running trixbox within a virtual environment, but I decided to revisit the possibility with the recent release of Windows Server 2008 R2 and the latest version of trixbox (currently 2.8) and this time had much greater success.
The only thing I had to do was install the Microsoft Hyper-V Integration Components for Linux on the machine and set the kernel parameters appropriately (as described below).
You can download the .iso from Microsoft at http://www.microsoft.com/downloads/details.aspx?displaylang=en&FamilyID=ab7f4983-93c5-4a70-8c79-0642f0d59ec2.
Currently, CentOS/RedHat doesn’t appear to be supported by Microsoft, but following the steps below will allow you to install the appropriate drivers (and confirm a successful intallation): -
- Mount the downloaded .iso on your trixbox machine
- Install the kernel-devel and gcc (GNU Compiler Collection) packages by running the commands below
yum install kernel-devel
yum install gcc
- Now you’ll need to mount the CD ROM using these commands
mkdir -p /mnt/cdrom
mount /dev/cdrom /mnt/cdrom
- Copy the contents of the CD to the local machine
cp -rp /mnt/cdrom /opt/linux_ic
- Unmount the CD ROM
- Run the driver setup
- Set the kernel boot parameters as per this article
- You’ll need to restart to initialise the drivers
shutdown -r now
- When the machine is back up and running, make sure the drivers are loaded by running the command below
lsmod | grep vsc
- This should give you a result similar to the following
Now you have the integration components installed, configure the rest of the options on your trixbox and test it out. I allocated mine 512MB RAM, and it doesn’t skip a beat while I performed audio streaming tests.
