Libvirt provides a portable, long term stable C API for managing the
virtualization technologies provided by many operating systems. It
includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware
vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER
Hypervisor.

For example: >>> dom.memoryStats() libvir: QEMU Driver error : Requested operation is not valid:\ domain is not running There are six such python API functions like so. The root reason is that generator.py script checks the type of return value of a python stub function defined in libvirt-api.xml or libvirt-override-api.xml to see whether to add the raise clause or not in python wrapper code in libvirt.py. The type of return value is supposed to be C types. For those stub functions which return python non-integer data type like string, list, tuple, dictionary, the existing type in functions varies from each other which leads problem like this. Currently, in generator.py, it maintains a buggy whitelist for stub functions returning a list type. I think it is easy to forget adding new function name in the whitelist. This patch makes the value of type consistent with C type "char *" in libvirt-override-api.xml. For python, any of types could be printed as string, so I choose "char *" in this case. And the comment in xml could explain it when adding new function definition. <function name='virNodeGetCPUStats' file='python'> ... - <return type='virNodeCPUStats' info='...'/> + <return type='char *' info='...'/> ... </function> |

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.
