Creating unique interfaceid in KVM (RHEL)

Consider the KVM VM has the below definition:

If you clone this VM using virt-clone utility, then the new VM will have the same interface id

If you need new interfaceid for every clone, then some libvirt py files will need change:

1) /usr/share/virt-manager/virtinst/deviceinterface.py

class VirtualPort(XMLBuilder):

    _XML_ROOT_NAME = "virtualport"

    type = XMLProperty("./@type")

    managerid = XMLProperty("./parameters/@managerid", is_int

    typeid = XMLProperty("./parameters/@typeid", is_int=True)

    typeidversion = XMLProperty("./parameters/@typeidversion"

    instanceid = XMLProperty("./parameters/@instanceid")

    interfaceid = XMLProperty("./parameters/@interfaceid")   <--- added="" div="" newly="">

2) /usr/share/virt-manager/virtinst/cloner.py

import uuid

and following line:

for iface in self._guest.get_devices("interface"):

    iface.target_dev = None

    if clone_macs:

        mac = clone_macs.pop()

    else:

        mac = VirtualNetworkInterface.generate_mac(self.conn)

    iface.macaddr = mac
    if iface.virtualport.type:

        iface.virtualport.interfaceid = uuid.uuid4() <--- added="" div="" newly="">
