Re: [Rdo-list] SR-IOV on openstack: no valid host is found

Sounds like issues in the environment, The PF (Physical function (external port)) connected to some switch, if so as Trunk? *From:* rdo-list-bounces(a)redhat.com [mailto:rdo-list-bounces@redhat.com] *On Behalf Of *Joe Talerico *Sent:* Wednesday, August 26, 2015 16:26 *To:* Pedro Sousa *Cc:* rdo-list(a)redhat.com *Subject:* Re: [Rdo-list] SR-IOV on openstack: no valid host is found On Wed, Aug 26, 2015 at 6:54 AM, Pedro Sousa <pgsousa(a)gmail.com&gt; wrote: Hi, Some update on this, although I can launch the VM and see the VF inside it, I have 2 problems 1º Sometimes I don't get ip from dhcp when I launch a new instance. Does the VF have the right VLAN tag? 2º I cannot ping the other hosts inside the tenant network using sr-iov nics. If I use ovs nics it works. Are VLANs setup properly?
