Hi , Despite the fact that my Guest has an IP address , by running this piece of code on a KVM host : ifaces_count = F_virDomainInterfaceAddresses(domain, &ifaces,VIR_DOMAIN_INTERFACE_ADDRESSES_SRC_LEASE, NULL); ifaces_count = F_virDomainInterfaceAddresses(domain, &ifaces,VIR_DOMAIN_INTERFACE_ADDRESSES_SRC_AGENT, NULL); I'm not able to get a ifaces_count different from -1 Additionnaly : - IP Addresses are not present within the xmldesc of this Guest.(not sure that they should appear there) I'm running libvirt-1.2.17-13.el7.x86_64 Did I misunderstood something ? As ovirt manager shows the address correctly , it should be possible to get it via libvirt ... Thanks for help. J.P. Ribeauville P: +33.(0).1.47.17.20.49 .
