Re: SR-IOV pool with static MAC address and vlan

Hi Paul, You can set the static MAC address and VLAN in the interface section of the VM xml. So it will not change even when the VM shuts down and restarts. VM interface xml: <interface type='network'> <mac address='52:54:00:85:e2:cd'/> <source network='hostdev_net'/> <vlan> <tag id='42'/> </vlan> </interface> And set the network(vf pool) with xml like below: # cat hostnet.xml <network> <name>hostdev_net</name> <forward mode='hostdev' managed='yes'> <pf dev='eth0'/> </forward> </network> (eth0 is the PF's name, refer to https://libvirt.org/formatnetwork.html#connectivity, hostdev part) or: # cat hostnet.xml <network> <name>hostdev_net</name> <forward mode='hostdev' managed='yes'> <address type='pci' domain='0x0000' bus='0x03' slot='0x10' function='0x0'/> <address type='pci' domain='0x0000' bus='0x03' slot='0x10' function='0x2'/> </forward> </network> (the address is VF's pci address, you can specify multiple addresses at once) # virsh net-define hostnet.xml # virsh net-start hostdev_net Hope it helps.
