# HG changeset patch # User Ian Jackson <Ian.Jackson@xxxxxxxxxxxxx> # Date 1277741623 -3600 # Node ID 408b0b6768fc7a789c032d40d48cd7ecb2042904 # Parent dcb1cd697788a647d392b5d0bb581976c978abb8 libxl: Specify no nics to qemu when no emulated nics qemu will default to one emulated NIC if no network configuration is specified on the command-line.
