Disks support in this driver was implemented with an assumption, that disk images can't be created by hand, without VM. So complex storage driver was implemented with workaround. This is not true, we can create new disks using ploop tool. So the first step to reimplement disks support in parallels driver is to do not use information from the storage driver, until we will implement VIR_STORAGE_TYPE_VOLUME disks. So after this patch disks can be added in the same way as in any other driver: you create a disk image and then add an entry to the XML definition of the domain with path to that image file, for example: <disk type='file' device='disk'> <driver type='ploop'/> <source file='/storage/harddisk1.hdd'/> <target dev='sda' bus='sata'/> <address type='drive' controller='0' bus='0' target='0' unit='0'/> </disk> This patch makes parallels storage driver useless, but I'll fix it later. Now you can create an image by hand, using ploop tool, and then add it to some domain. 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.
