[Libvir] python libvirt methods to virDomainBlockStats and virDomainInterfaceStats

Hello all, I'm using libvirt from cvs, and in libvirt.h there are virDomainBlockStats, and virDomainInterfaceStats calls. I think it is compiled into libvirtmod, then I'm trying to write two methods, blockStats, and interfacesStats in the class virDomain at the libvirt.py library file. I'm not a specialist in python programming and it's not working. Bellow folow the code I have been wrote: def blockStats(self): """Block device stats for virDomainBlockStats """ ret = libvirtmod.virDomainBlockStats(self._o) if ret is None: raise libvirtError ('virDomainBlockStats() failed', dom=self) return ret def interfaceStats(self): """Network interface stats for virDomainInterfaceStats.""" ret = libvirtmod.virDomainInterfaceStats(self._o) if ret is None: raise libvirtError ('virDomainInterfaceStats() failed', dom=self) return ret Any help will be welcome. Best regards -- Marco Sinhoreli

Complementing the last mail: Importing the libvirtmod the virDomainInterfaceStats, and virDomainBlockStats aren't listed (using help(libvirtmod)) Regards On 9/26/07, Marco Sinhoreli <msinhore@gmail.com> wrote:

Investigating the source, I find the libvirtclass.txt file in libvirt-source/python directory with these contents: [...] Functions failed: virConnSetErrorFunc virDomainGetSchedulerParameters virConnectGetVersion virSetErrorFunc virDomainSetSchedulerParameters virConnCopyLastError virDomainBlockStats virCopyLastError virDomainGetVcpus virDefaultErrorFunc virResetError virDomainInterfaceStats On 9/26/07, Marco Sinhoreli <msinhore@gmail.com> wrote:

This isn't going to work because you need to pass the path to both calls. I think this requires a hand-written C binding.
