After some time with a lot to do outside the computer world, I am now continuing my "KVM-Project". I have gotten all my KVM-Guest to run separately, but when I try to start more then one at the same time I get the following error message and the second Guest does not start: warning: could not configure /dev/net/tun: no virtual network emulation The scripts used to start the Guests looks like this: Guest-A: kvm \ -net nic,vlan=1,model=rtl8139,macaddr=DE:ED:BE:EF:01:04 -net tap,vlan=1,ifname=qtap1,script=no,downscript=no \ -net nic,vlan=3,model=rtl8139,macaddr=DE:ED:BE:EF:03:04 -net tap,vlan=3,ifname=qtap3,script=no,downscript=no \ -m 2048 -k de-ch -vnc :4 -daemonize \ Robbie.qcow2 Guest-B: kvm \ -net nic,vlan=1,model=rtl8139,macaddr=DE:ED:BE:EF:01:03 -net tap,vlan=1,ifname=qtap1,script=no,downscript=no \ -net nic,vlan=3,model=rtl8139,macaddr=DE:ED:BE:EF:03:03 -net tap,vlan=3,ifname=qtap3,script=no,downscript=no \ -m 2048 -k de-ch -vnc :3 -daemonize \ Wilmer.qcow2 I suspect that something is not 100% correct with my network setup. I want both of the Guest to be able to access the same qtap's (1 and 3). br1 = qtap1 + eth1 br3 = qtap3 + eth3 Is it not possible to use the same qtap for two different Guests? Do I need to setup one qtap for each Guste and configure it like this: br1 = qtap1a + qtap1b + eth1 Just asking for some advice before I start fiddling around with my network- setup again.
