Error creating macvtap interface device or resource busy. I am using gentoo linux with kernel 4.

Error creating macvtap interface device or resource busy One possible method of eliminating this problem would be to create a separate macvtap interface for host use, and give it the IP configuration previously on the physical ethernet (see this page for an example of how to manually configure an interface on the physical host to use macvtap, and this page for a script) - in this way, the host would be an equal peer Or I can edit the xml to have a different mac address. Please make sure the network type is 'macvlan' and not 'ipvlan' Yes you cannot use eth0 in that case. The VM is fully functional. nmcli connection add type macvlan dev eth0 mode bridge tap yes ifname macvtap0 Where eth0 is your physical device. please make sure the network type is 'macvlan' and not 'ipvlan' You are running this container on a Synology device, and I do not think that the Synology kernel in DSM supports macvtap, because it uses an old Linux kernel -----Solved----Turns out it was IWD that was causing the misbehavior not systemd. I really feel like this shouldn't be a thing. I know this is a bit of a noob question so feel free to point me somewhere else if need-be. I only want the virtual OPNsense interface to have an IP, not the host interface. MACVTAP 的实现基于传统的 MACVLAN. If Docker needs to create the macvlan interface in a subinterface so is tagged, and on verious sets of documentation from different vendors the lack of mention of VLANs, VLAN How to create a new partition in RHEL 7 without reboot ? Disk /dev/sdX is being used for system partition, for example for /boot and / (root). Macvtap interfaces directly connect the lower device (in this case eth0) with the 'tap' consumer (qemu) – and because they redirect all packets sideways to the 'tap' consumer, nothing gets forwarded "up" to the host OS network stack where a bridge could see them (which would need a 3-way split), which means they can have neither a L3 IP address nor a L2 Create your macvtap interface. Either use dhcpcd@enp2s5. Likewise, frames sent by the VM are injected on the host's physical interface toward outside. 40 ipvlan40 # in two separate terminals docker run --net=ipvlan40 -it --name ivlan_test5 --rm alpine /bin/sh docker run --net=ipvlan40 -it --name @Mic92 OK so I think this is due to using networking. It did not work for me though. dhcp Trying to start the virtual machine gives me following error. 134. I've spent hours (days) googling with no joy.
