I am sure the firewalled is disable
and I didn't specify a VLAN for the public network range
and I the IP (10.13.56.254) is the network gateway.
I split up six virtual machines on one physical machine to deploy these

Could it be a problem of applying virtual machines to virtual machines on
top of virtual machines? This problem may involve layer 2 virtualization
technology, I am not very familiar with it
two systemvms have the same logs in the following
