Parallels Cloud Server has one serious discrepancy with libvirt: libvirt stores domain configuration files in one place, and storage files in other places (with the API of storage pools and storage volumes). Parallels Cloud Server stores all domain data in a single directory, for example, you may have domain with name fedora-15, which will be located in '/var/parallels/fedora-15.pvm', and it's hard disk image will be in '/var/parallels/fedora-15.pvm/harddisk1.hdd'. I've decided to create storage driver, which produces pseudo-volumes (xml files with volume description), and they will be 'converted' to real disk images after attaching to a VM. So if someone creates VM with one hard disk using virt-manager, at first virt-manager creates a new volume, and then defines a domain. We can lookup a volume by path in XML domain definition and find out location of new domain and size of its hard disk. Signed-off-by: Dmitry Guryanov <dguryanov@parallels.com>
LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
