That video is using VirtualBox. The error mentions macvtap – I think the GUI should allow you to add the tap as a virtio.

I would like to kindly request support/advice/feedback about an issue that I am having with the Virtual Machine Manager and OpenVSwitch. I am deploying 7 Virtual Machines (Virtual Machine Manager 1.4.1, CentOS 7) and need to connect them to an OpenVSwitch (2.5.2) bridge for SDN purposes. I installed OVS without any complications following this guide: https://gist.github.com/umardx/a31bf6a13600a55c0d07d4ca33133834 Later on, I created an OVS bridge with 7 ports, each one for my 7 VMs, following this very clear tutorial: https://www.youtube.com/watch?v=rYW7kQRyUvA At the moment I Power On any of the 7 VMs I get the following error: Error starting domain: error creating macvtap interface macvtap0@vport5 (52:54:00:55:18:e7): Device or resource busy Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/asyncjob.py", line 88, in cb_wrapper callback(asyncjob, *args, **kwargs) File "/usr/share/virt-manager/virtManager/asyncjob.py", line 124, in tmpcb callback(*args, **kwargs) File "/usr/share/virt-manager/virtManager/libvirtobject.py", line 83, in newfn ret = fn(self, *args, **kwargs) File "/usr/share/virt-manager/virtManager/domain.py", line 1489, in startup self._backend.create() File "/usr/lib64/python2.7/site-packages/libvirt.py", line 1039, in create if ret == -1: raise libvirtError ('virDomainCreate() failed', dom=self) libvirtError: error creating macvtap interface macvtap0@vport5 (52:54:00:55:18:e7): Device or resource busy I've tried cloning the VMs thinking that adding the network interface later after creating the VM was the problem but the error continues to show up. In addition I restarted the OVS service and the result is the same. Thanks in advance for your attention, I apologize if this is not the correct channel to escalate this error, and would appreciate that you point me where I should direct it to. Kind Regards, Sebastian
