Cannot use OVS commands with libvirt
I have an Ubuntu 18.04 on which I have installed OVS. I have created a bridge 'br1', and the output of
$sudo ovs-vsctl show
Bridge "br1"
Port "enp0s25"
Interface "enp0s25"
Port "br1"
Interface "br1"
type: internal
I am now trying to create VMs with virt-install and have them create a port on the OVS bridge and connect to it. Following the virt-install manual, in my VM configuration file I added:
<interface type='bridge'>
<source bridge='br1'/>
<virtualport type='openvswitch'>
</virtualport>
<target dev='tap0'/>
<model type='rtl8139'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x05' function='0x0'/>
</interface>
And when I try to start the VM I get the following error:
internal error: Unable to add port tap0 to OVS bridge br1
And looking further into the libvirt logs I found:
libvirtd[2926]: 2018-12-11 11:53:10.382+0000: 2930: error : virCommandWait:2601 :
internal error: Child process (ovs-vsctl --timeout=5 -- --if-exists del-port tap0 --

set Interface tap0 external-ids:iface-status=active) unexpected exit status 126:
libvirt: error : cannot execute binary ovs-vsctl: Permission denied
To use the OVS commands like ovs-vsctl you need to use sudo, so my user is in the sudoers group, but I can't manage to get this to work.
Any idea is welcome and kindly appreciated. Thank you, and have a nice day :)
