How to discover all the instances in each vlan?using topology discover or any other way
hello,erveyone. I need to discover all the VMs in the Openstack. I've developed a topology discovery program using ICMP and runs in a VM. When the network mode is Flat or FlatDHCP, it works well, but when the network mode is Vlan, it cannot find other Vlan's machine. I konw it's caused by the isolation of Vlan. So how to find all the VMs when the network mode is Vlan??? We can use any way except checking the database... Thanks in advance!
