Since 3.3.0, Coalesce setting is supported.
This case is to set coalesce and check for 4 network types and each guest interface type.
Only network/bridge guest interface type take effect for setting interface coalesce.
For each host network type, guest can use bridge/network interface type to set coalesce
except macvtap network type.
Execute 'ethtool -c ${interface}|grep "rx-frames"' and anylize the output to check
whether coalesce setting take effect or not.
For macvtap network type, guest can start but query coalesce will fail.
1. For default host network
network definition is below:
<network>
<name>default</name>
<bridge name="virbr0"/>
<forward/>
<ip address="192.168.122.1" netmask="255.255.255.0">
<dhcp>
<range start="192.168.122.2" end="192.168.122.254"/>
</dhcp>
</ip>
</network>
This is default network.
1) guest interface type 'bridge' and set coalesce:
<interface type='bridge'>
<mac address='52:54:00:a7:4d:f7'/>
<source bridge='virbr0'/>
<target dev='vnet0'/>
<model type='virtio'/>
<coalesce>
<rx>
<frames max='64'/>
</rx>
</coalesce>
<alias name='net0'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/>
</interface>
2) guest interface type 'network' and set coalesce:
<interface type='network'>
<source network='default'/>
<model type='virtio'/>
<coalesce>
<rx>
<frames max='32'/>
</rx>
</coalesce>
</interface>
2. For bridge host network
This mode need true bridge in host network.
'nmcli con add type bridge con-name br0 ifname br0'
1) guest interface type 'bridge' and set coalesce:
<interface type='bridge'>
<mac address='52:54:00:8e:f3:6f'/>
<source bridge='br0'/>
<target dev='vnet0'/>
<model type='virtio'/>
<coalesce>

</rx>
</coalesce>
<alias name='net0'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x0a' function='0x0'/>
</interface>
2) guest interface type 'network' and set coalesce:
First, define one virtual network for bridge br0
'virsh net-define net-br0.xml'
'virsh net-dumpxml net-br0'
<network>
<name>net-br0</name>
<forward mode='bridge'/>
<bridge name='br0'/>
</network>
Secondly, use this network for guest
<interface type='network'>
<source network='net-br0'/>
<model type='virtio'/>
<coalesce>
<rx>
<frames max='32'/>
</rx>
</coalesce>
</interface>
3. For openvswitch bridge host network
This mode need true openvswitch bridge in host network.
'ovs-vsctl add-br ovsbr0'
1) guest interface type 'bridge' and set coalesce:
<interface type='bridge'>
<mac address='52:54:00:8e:f3:6f'/>
<source bridge='ovsbr0'/>
<virtualport type='openvswitch'/>
<target dev='vnet0'/>

</rx>
</coalesce>
<alias name='net0'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x0a' function='0x0'/>
</interface>
2) guest interface type 'network' and set coalesce:
First, define one virtual network for openvswitch bridge ovsbr0
'virsh net-define net-ovsbr0.xml'
'virsh net-dumpxml net-ovsbr0'
<network>
<name>net-ovs0</name>
<forward mode='bridge'/>
<bridge name='ovsbr0'/>
<virtualport type='openvswitch'/>
</network>
Secondly, use this network for guest
<interface type='network'>
<source network='net-ovs0'/>
<model type='virtio'/>
<coalesce>
<rx>
<frames max='32'/>
</rx>
</coalesce>
</interface>
4. For macvtap bridge mode on host network
For this mode, first, create one virtual network.
Note, should set dev to one ture physical interface.
'virsh net-define net-br-macvtap.xml'
'virsh net-dumpxml net-br-macvtap'
<network>
<name>net-br-macvtap</name>
<forward dev='eno1' mode='bridge'>
<interface dev='eno1'/>
</forward>
</network>
Set guest to use this macvtap network and set coalesc
<interface type='network'>
<mac address='52:54:00:6e:f4:f1'/>
<source network='net-br-macvtap'/>
<model type='virtio'/>
<coalesce>
<rx>
<frames max='32'/>
</rx>
</coalesce>
<address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/>
</interface>
Steps in this test:
1. Prepare test environment,destroy or suspend a VM.
2. Prepare network if necessary.
3. Edit guest interface with definite network and set coalesce.
4. Start guest and check whether coalesce setting take effect.
5. Recover network and guest.
