Hello,
I was planning on adding multiple physical functions using the built in SR-IOV features offered by libvirt to a create a bigger pool of virtual functions using the
<forward mode='hostdev' managed='yes'> heading
(I want to be able to use more virtual machines then there are virtual functions available on an ethernet port).
As soon as I try to define multiple physical functions in a pool, I get this error:
error: Failed to define network from biggernetwork.xml error: XML error: Only one <pf> element is allowed in <forward> of network bigger network
when using this command:
sudo virsh net-define biggernetwork.xml
on the following XML document:
<network> <name>bigger network</name> <forward mode='hostdev' managed='yes'> <pf dev='eth5'/> <pf dev='eth7'/> </forward> </network>
You need to define only the PF and libvirt will handle the rest: https://wiki.libvirt.org/page/Networking#Assignment_with_.3Cinterface_type.3... Michal
