Configuring KVM for Pexip Infinity
This section describes the KVM configuration required before you install the Management Node or install a Conferencing Node.
Prerequisites
This guide assumes that you have a KVM environment already installed. You must ensure that:
- the KVM environment may be managed through libvirt
- the virt-manager, virsh and virt-install applications are available for use on the client system that is managing the KVM environment; to do this, run the command:
sudo apt-get install virt-manager libvirt-bin
The libvirt command line tools are used to import the disk image and create the VM. Note that we use the libvirt command line tools to perform the import as they provide greater control than Virtual Machine Manager. For more information, see http://libvirt.org/drvqemu.html.
Synchronizing time
Pexip Infinity uses NTP servers to obtain accurate system time. This is necessary to ensure correct operation, including configuration replication and log timestamps.
All host servers must be synchronized with accurate time before you install the Management Node or Conferencing Nodes on them.
NTP must be enabled on the Management Node VM before you deploy any Conferencing Nodes (this is done during installation of the Management Node).
We strongly recommend that you configure at least three distinct NTP servers or NTP server pools on all your host servers and the Management Node itself. This ensures that log entries from all nodes are properly synchronized.
The VMs hosting the Management Node and Conferencing Nodes use the UTC timezone, and all logs are in UTC. Do not attempt to change the timezone on these systems. Note however that the administrator web interface uses your local time.
Install the NTP package on your host server using the appropriate package management tool for your Linux distribution.
Enabling automatic startup
You can only enable automatic startup after the Management Node or Conferencing Node has been deployed.
To enable automatic startup using Virtual Machine Manager:
- Connect to the Virtual Machine Manager (virt-manager) that is managing the node's VM.
-
Select the node's VM and then, from the toolbar, select the
icon .A new window for that VM is opened.
- If necessary, select to display the VM information.
- From the sidebar menu, select .
- Select the Start virtual machine on host boot up check box.
- Select .
