The correct vlanid range is 0~4095. After merging this patch, we can not validate a interface xml with vlanid >= 4096. [root@localhost ~]# cat vlan.xml <interface type='vlan' name='eno1.4096'> <start mode='onboot'/> <protocol family='ipv4'> <dhcp/> </protocol> <vlan tag='4096'> <interface name='eno1'/> </vlan> </interface> [root@localhost ~]# virt-xml-validate vlan.xml vlan.xml:1: element interface: Relax-NG validity error : Invalid sequence in interleave vlan.xml:6: element vlan: Relax-NG validity error : Element interface failed to validate content vlan.xml:6: element vlan: Relax-NG validity error : Element vlan failed to validate attributes vlan.xml fails to validate [root@localhost ~]# Here is a ip command help on this.
