Hi Andrew I am not aware of any issue to connect engine to specific switch (try to connect other host to the switch to check this assumption) Looks like it's auto-negotiation issue. Try to disable it (on the switch side too) Regards, Genadi ----- Original Message ----- From: "Andrew Precht" <andrewprecht06@gmail.com> To: users@ovirt.org Sent: Thursday, May 28, 2015 12:37:57 AM Subject: [ovirt-users] connecting my oVirt engine to a 100mb switch Hi all, I’m having problems connecting my oVirt engine to a 100mb switch. I’m not having any problems connecting to 1gb. But, I need to also have a connection to a 100mb network. I’ve tried configuring ethtool_opts on the interface. However, this only results in the NIC not coming up and showing: Speed: Unknown! and Duplex: Unknown! (255), when I run ethtool ethX Is it possible to connect the engine to a 100mb switch? Thanks PS. I also posted this question over on the oVirt G+ page. I apologize if that's incorrect but I have G+ open all day... _______________________________________________ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
