* Fixed regression when using additional disks. Now disk_bus setting
applies only to main disk.
* Added ability to change additional disk bus on reload. Updated readme.

* Added the suspend_mode domain specific option. Now it can perform a
managed save/resume. Switching this domain specific option can be done
when the domain is supended, it will correctly resume the domain.

* Added support to modify domain specific options on already defined
domain, updated relevant documentation. For list of modifiable options
please see updated documentation.
* Added new domain specific option - uuid. To force domain UUID when
creating new VM.

Readme file is large, so navigation may be quite compilated.
Table of contents improves navigation but adds a little work when the content is changed.

For better VM performance CPU type should be set not to qemu64, but to
the host cpu type.
For example see the difference (uppercased)
flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov
pat pse36 clflush mmx fxsr sse sse2 ss syscall nx rdtscp lm constant_tsc
rep_good nopl eagerfpu pni pclmulqdq vmx ssse3 cx16 pcid sse4_1 sse4_2
x2apic popcnt tsc_deadline_timer aes xsave avx hypervisor lahf_lm
tpr_shadow vnmi flexpriority ept xsaveopt
Added extensions when emulating host cpu model:
flags : fpu VME de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov
PAT pse36 clflush mmx fxsr sse sse2 SS syscall nx RDTSCP lm CONSTANT_TSC
rep_good nopl EAGERFPU pni PCLMULQDQ vmx SSSE3 cx16 PCID SSE4_1 SSE4_2
x2apic popcnt TSC_DEADLINE_TIMER AES XSAVE AVX hypervisor lahf_lm
tpr_shadow vnmi flexpriority ept XSAVEOPT
Nested virtualization requires VMX/SVM capabilities, which are still
being added when domain.nested is set to true.
Using the current default value for cpu_mode everyone will benefit from
the better VMs performance.

This is required because in current versions of libvirt, it is not
possible to specify a boot order when attaching a device; therefore we
can only parse the entire domain XML after all devices have been created
and then assign boot ordering according to the Vagrantfile
specification. This allows us to specify exact boot order for hd, cdrom
and network.
Vagrant already supports VMs without boxes with Docker.
We leverage this in libvirt as well. The use case for this is to PXE
oot a vagrant VM that is then installed over the network then
installed over the network; a different use case would be to test PXE
booted clients that do not use a hard drive whatsoever.
```ruby
Vagrant.configure("2") do |config|
config.vm.provider :libvirt do |libvirt|
# very useful when having mouse issues when viewing VMs via VNC
libvirt.input :type => "tablet", :bus => "usb"
end
end
```
Useful when configuring Virtualized Switch topologies using Switch VMs like Cumulus
Linux.
vagrant network interface auto_config is disabled in the code. This may be
re-enabled in a future update, once it is better understood how to
auto configure these types of links. All guestOS ports, for now, that are
connected to a tcp tunnel are in a link down state.
TCP tunnels allow guest OSes to exchange STP and LLDP information as
if they are directly connected to each other.
This is not possible with the default virtual switch network mode.
Reference:
https://libvirt.org/formatdomain.html#elementsNICSTCP
Allow control of the volume size to be increased from the box default
virtual_size value so that it is possible to use a box configured with a
minimal initial disk size and create virtual guests with larger disk
sizes.
Warn the user and ignore sizes that are less than the box size, and
inform them that a manual filesystem resize will be needed to take
advantage of the additional available disk space.
fixes: #37
I ran into a trouble, as my box(ubuntu) was *not* installed zlib1g-dev package
by default, so update README.md to hint guys to install this package for
ubuntu/debian system.
