To simulate shared SAN storage an additional libvirt
disk property needs to be set which disables caching.
Also updated the documentation to document this new
property and added an example on how to simulate
shared SAN storage
Closes#648
libvirt has supported specification of a guest NUMA topology since
0.9.8. This functionality can be used for basic validation of some
NUMA-dependent features during development. Add basic configuration
support, by allowing the user to specify how many NUMA nodes the
instance may have.
The following options are added:
* numa_nodes - Defaults to none
For additional information on specifying NUMA nodes with Libvirt, see:
* https://libvirt.org/formatdomain.html#elementsCPU
* Wrap to 80 characters
* Use 'Vagrant', not 'vagrant', where appropriate
* Format code as such
* Mark up code type where possible (shell, ruby, etc.)
* Don't use code fences inline
* Misc other changes
Example:
config.vm.provider :libvirt do |libvirt|
# Create a virtio channel for use by the qemu-guest agent (time sync, snapshotting, etc)
libvirt.channel :type => 'unix', :target_name => 'org.qemu.guest_agent.0', :target_type => 'virtio'
# Forward traffic to 1.2.3.4 from the guest, to the specified socket on the host
libvirt.channel :type => 'unix', :target_type => 'guestfwd', :target_address => '1.2.3.4', :target_port => '9999',
:source_path => '/tmp/foo'
end

Use the more conservative path if either disks or cdroms present for
the domain configuration.
Domain destroy including volumes will attempt to delete any attached
CDROM images as they are registered as volumes. Resulting in the
following error message:
fog-libvirt-0.0.3/lib/fog/libvirt/requests/compute/volume_action.rb:6:in
`delete': Call to virStorageVol Delete failed: cannot unlink file
'<path-to-iso>': Success (Libvirt::Error)
