Maybe obvious but have you set the firewall on Win10 to allow pings ( it defaults to blocking them).

Unfortunately the BRIGDE cannot ping Win10. It can only ping router. _______________________________________________ Users mailing list -- users(a)ovirt.org To unsubscribe send an email to users-leave(a)ovirt.org Privacy Statement: https://eur02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.ovi... oVirt Code of Conduct: https://eur02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.ovi...

Hello Dominik, Please find attached the picture below. As show in the picture, what I am trying to achieve, is to create a software tap to create a connection between the bridge and windows machine. The problem also exists when trying to setup the same infrastructure using vlans or logical networks. ovirt-provider-ovn works perfect for Router to Windows connection etc. Please keep in mind that all the infrastructure shown in the picture consists only by VMs. Thanks for fast response. ________________________________ From: Dominik Holler <dholler(a)redhat.com&gt; Sent: Friday, October 11, 2019 11:47 AM To: con_louca(a)hotmail.com <con_louca(a)hotmail.com&gt; Cc: users(a)ovirt.org <users(a)ovirt.org&gt; Subject: Re: [ovirt-users] Re: Bridge issue On Fri, 11 Oct 2019 08:37:27 -0000 con_louca(a)hotmail.com wrote: ok, so the problem seems to be that the external network connecting BRIGDE to Win10 is not working. Can you please share the current ovn-controller.log of the hosts running BRIGDE and Win10? Were both hosts installed into a cluster with ovirt-provider-ovn as default network provider? Does reconfiguration of ovn like described in https://www.ovirt.org/documentation/admin-guide/chap-External_Providers.h... fixes the issue? If not, can you please share the ovn-controller.log after the reconfiguration?

I re-created your scenario, and I noticed that an On Mon, Oct 14, 2019 at 9:36 AM <con_louca(a)hotmail.com&gt; wrote: It is not possible to have multiple MAC addresses on a single port of a network of ovirt-provider-ovn, because of the way OVN is working. If the link from the client VM to the bridge VM (and from bridge VM to router) would be usual (linux bridge based) VLANs, the scenario would work.
