The path argument in virDomainInterfaceStats() is intended to be the name of the tap interface on the host that's used to connect the guest to the network, eg "vnet0". You can find this name by retrieving the XML for the active domain, and looking for <target dev='xxx'/> in each <interface> element - the 'xxx' is the tap interface name, and should be put in the path arg when calling virDomainInterfaceStats().

Please Help me Too !!
Basically, it's string(/domain/devices/interface[n]/target/@dev) where n is index of the interface you wanna get statistics for. For example, if I have this in XML (virDomainGetXMLDesc()): ... <interface type='network'> <mac address='52:54:00:57:f5:50'/> <source network='default'/> <target dev='vnet0'/> <model type='virtio'/> <filterref filter='no-ip-spoofing'> <parameter name='ip_learning' value='dhcp'/> </filterref> <alias name='net0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/> </interface> <interface type='direct'> <mac address='52:54:00:16:e6:5c'/> <source dev='eth0' mode='bridge'/> <target dev='macvtap0'/> <model type='virtio'/> <alias name='net1'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x08' function='0x0'/> </interface> ... I would query for stats: virDomainInterfaceStats(dom, "vnet0", ...); virDomainInterfaceStats(dom, "macvtap0", ...); Michal
