GitHub user miloserdoff added a comment to the discussion: Error creating VLAN
@rajujith Hello. I changed the interface names and decided to look at the Cloudstack Agent log. It gave me an error: com.cloud.exception.InternalErrorException: Failed to create vnet 805: Cannot find device "br-805" /usr/share/cloudstack-common/scripts/vm/network/vnet/modifyvlan.sh: line 37: /proc/sys/net/ipv6/conf/br-805.805/disable_ipv6: No such file or directory Cannot find device "br-805.805" Failed to create vlan 805 on pif: br-805.
