I'm not native English speaker so I'm not sure I do understand meaning correctly or if the wording is OK...
NOTE: sudo calls closefrom(2). In order to have more than one fd passed tap interface, a line to sudoers akin to: Defaults closefrom_override then calling sudo via 'sudo -C 5 -u $USER qemu-system-i386 ..' is required. See sudoers(5) and sudo(8) for details. "...more than one fd passed tap interface,...". Is this correct? What does it want to say exactly? I made my qemu VM work with multiple ifaces with following command, each VM's iface has its own tun(4) device on the OpenBSD host. $ sudo sh -c "sudo -C 5 -u jirib qemu-system-x86_64 -net nic,model=virtio,vlan=0 \ -net tap,vlan=0,fd=3 -net nic,vlan=1,model=virtio -net tap,vlan=1,fd=4 \ -no-fd-bootchk -drive file=~/tmp/qemu/virtual.img,if=virtio,format=qcow2 \ -drive file=~/downloads/install55.iso,if=scsi,media=cdrom \ -boot order=cd,once=d 3<>/dev/tun0 4<>/dev/tun1" Am I doing multi-nic qemu VM correctly? jirib
