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

Wed Aug 26 10:54:45 UTC 2015

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?

Thanks,
Pedro Sousa
