QA:Testcase Virt Multiqueue Net

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
  • Note: you might get an selinux notification on the host: https://bugzilla.redhat.com/show_bug.cgi?id=1016326
• 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.
