hi all,
I'm trying to use openvswitch with kvm in Ubuntu latest version following the
commands in INSTALL.KVM file but when I try to run the kvm command, it fails
with error "Device 'tap' could not be initialized". Fyi, I have initialized the
tap devices using tunctl commands and ifconfig command also shows me the
configuration success. Any idea? Am I missing something here ?
bash$ sudo kvm -m 512 -net nic,macaddr=00:11:22:EE:EE:EE -net
tap,script=/etc/ovs-ifup,downscript=/etc/ovs-ifdown -drive
file=~/iso_images/linux-5.6.0-i386.iso,boot=on
/etc/ovs-ifup: could not launch network script
kvm: -net tap,script=/etc/ovs-ifup,downscript=/etc/ovs-ifdown: Device 'tap'
could not be initialized
bash$ ifconfig
.........
