Hi,

while writing SharpLibVirt I ran into several problems with some functions:

virDomainInterfaceStats ------------------------------------ It is not possible get any result, because of error "invalid argument in invalid path, 'user.0' is not a known interface". But inside LOG for this domain is

"... -net user,vlan=0,name=user.0 ... "

It is not possible get stats for nic.0 also. Tested on KVM hypervisor.

For KVM the interfaces are called things like "vnet0", "vnet1" etc. What you should do is call virDomainGetXMLDesc[1] on the domain of interest, and then parse out the /domain/devices/interface/target node from the XML. The dev attribute gives the network name[2]. virt-top contains code to do this. [1] http://libvirt.org/html/libvirt-libvirt.html#virDomainGetXMLDesc [2] http://libvirt.org/formatdomain.html#elementsNICSVirtual

virStoragePoolIsActive and virStoragePoolIsPersistent ------------------------------------------------------------------------------- Both cause crash of libvirt deamon. I dont know why.

Tested on 0.7.4 and Qemu 0.11.0

If there isn't a bug about this, then please file one.
