Description

Configure multiple networking queues for your VM. This is a performance optimization.

Setup

Functioning virt host and VM created on F20+.

How to test

  • Start with a shutoff VM. Edit the guest XML: sudo virsh edit test-day-vm
  • In the <interface> block, add the following XML: <driver name='vhost' queues='4'/>
  • Save and exit
  • Launch the VM, login, go to a root terminal.
  • Enable the queues with: ethtool -L eth0 combined 4
  • Ping something to verify networking at least didn't fall over :)
  • Shutdown the VM, undo the changes if desired.

Expected Results

No obvious errors occur, all results are as indicated.
