Lin Ma 11a887ece5 cli: --disk: Add driver.metadata_cache options
Properly setting the metadata cache size can provide better performance
in case of using big qcow2 images.

This patch introduces two driver options:
* driver.metadata_cache.max_size
* driver.metadata_cache.max_size.unit

E.g. --disk ...,driver.type=qcow2,\
     driver.metadata_cache.max_size=2,\
     driver.metadata_cache.max_size.unit=MiB

BTW, Metadata cache size control is currently supported only for qcow2.
Regarding how to properly caluclate the cache size of qcow2, Please refer
to qemu's documentation.

Virtual Machine Manager

virt-manager is a graphical tool for managing virtual machines via libvirt. Most usage is with QEMU/KVM virtual machines, but Xen and libvirt LXC containers are well supported. Common operations for any libvirt driver should work.

Several command line tools are also provided:

  • virt-install: Create new libvirt virtual machines
  • virt-clone: Duplicate existing libvirt virtual machines
  • virt-xml: Edit existing libvirt virtual machines/manipulate libvirt XML

For dependency info and installation instructions, see the INSTALL.md file. If you just want to quickly test the code from a git checkout, you can launch any of the commands like:

./virt-manager --debug ...
