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

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.

2º I cannot ping the other hosts inside the tenant network using sr-iov nics. If I use ovs nics it works.

Anyone has experienced this issues?
