Good day. I try to use network w/ kvm - just like I did it using qemu: sudo kvm -localtime -hda hda -m 128 -net nic -net tap but it returns me: Incorrect number of arguments for command Usage: brctl addif <bridge> <device> add interface to bridge /etc/kvm/kvm-ifdown: could not launch network script I have checked kvm --help and have seen the same syntaxis. What is wrong? Or how do You give a network access to Your KVMs? Thank You for Your time.
