Xenner fails to identify TAP device because libvirt does not configure MAC address
Last modified: 2008-03-13 17:38:32 EDT
Description of problem:
Xenner needs to know the name of the TAP devices used for guest networking. When
the libvirt QEMU driver invokes Xenner it merely passes a file descriptor.
Xenner turns this into a interface name by querying each network interface in
turn looking for one with matching mac address.
libvirt though does not set the MAC address on the tap device it creates, so
Xenner never finds the matching device. The QEMU driver can simply set the MAC
address on the TAP device before invoking Xenner.
