Hi there,
Finally I got the answer from google search, refer to https://blog.flyingpenguintech.org/2017/12/ipv6-with-macvtap-and-libvirt.html
This is expected. With trustGuestRxFilters="yes", ipv6 works well.
# virsh dumpxml vm1 --xpath //interface
<interface type="direct" trustGuestRxFilters="yes">
<mac address="52:54:00:f5:0d:b1"/>
<source dev="eno1" mode="bridge"/>
<target dev="macvtap1"/>
<model type="virtio"/>
<alias name="net0"/>
<address type="pci" domain="0x0000" bus="0x01" slot="0x00" function="0x0"/>
</interface>
<interface type="direct" trustGuestRxFilters="yes">
<mac address="52:54:00:f5:0d:b1"/>
<source dev="eno1" mode="bridge"/>
<target dev="macvtap1"/>
<model type="virtio"/>
<alias name="net0"/>
<address type="pci" domain="0x0000" bus="0x01" slot="0x00" function="0x0"/>
</interface>

Hi there,I have a question regarding direct type interfaces. Would someone be able to take a look at it?When I start 2 VMs on the same host with interface "direct type + bridge mode", just as below:<interface type="direct"><mac address="52:54:00:9e:7b:51"/>
<source dev="eno1" mode="bridge"/>
<model type="virtio"/>
</interface>The 2 VMs can connect to each other via ipv4, but can not connect to each other via ipv6.Maybe it's related to some kernel parameters, but I don't know how to debug.Is there anyone who can help me?Thank you!
