We bought a Dell server with VMWare ESXi 6.5 in 2017.
I am very sure that the MAC-address are DIFFERENT between the original-VM and the cloned-VM.
(I used
vmkfstools -i "${PREFIX_DIR}/${FROM_VM}/${FROM_VM}_0.vmdk" "${PREFIX_DIR}/${TO_VM}/${TO_VM}_0.vmdk" -d thin
sed "s/${FROM_VM}/${TO_VM}/g" "${PREFIX_DIR}/${FROM_VM}/${FROM_VM}.vmx" > "${PREFIX_DIR}/${TO_VM}/${TO_VM}.vmx"
and clicked on "I copied the VM" to do the cloning.)
However, it seems like something happened in VM-network and both VMs received same IP from the
outside-DHCP-server.
It's possible that we need to use vSphere to do this cloning-feature though~
