Support full clone when cloning VM with vcsim

[qiyanqi]

I have multiple mock hosts, and trying to create vm template on each host with vcsim. I found the cloned VM share config.hardware.device.

Is it possible to support full clone? The expectation is each VM could have its own device but not share.

Below is an example and the script to show the issue:

clone VM1 from DC0_H0_VM0, the virtual disk point to “[host-1-local-dc] clonevm_host_1/clonevm_host_1.vmdk”
After clone VM2 from DC0_H0_VM0, virtual disk for DC0_H0_VM0, VM1, VM2 are all changed to the same vmdk [host-2-local-dc] clonevm_host_2/clonevm_host_2.vmdk”.

#!/bin/bash

# run vcsim:  ./govmomi/vcsim/vcsim -dc 1 -standalone-host 3 -vm 1

export GOVC_URL=https://user:pass@127.0.0.1:8989/sdk; export GOVC_INSECURE=1


setuphost() {
    id=$1

    # create local datastore
    rm -rf /tmp/datastore-${id}; mkdir -p /tmp/datastore-${id}
    govc datastore.create -type local -name host-${id}-local-dc -path /tmp/datastore-${id} DC0_H${id}

    # clone vm from template
    govc vm.clone -vm DC0_H0_VM0 -template=true -dc DC0 -ds host-${id}-local-dc -pool=/DC0/host/DC0_H${id}/Resources clonevm_host_${id}
}

setuphost 1
echo "###### clonevm_host_1:"
govc object.collect -o -dump /DC0/vm/clonevm_host_1 config.hardware.device|grep FileName
setuphost 2
echo "###### clonevm_host_1:"
govc object.collect -o -dump /DC0/vm/clonevm_host_1 config.hardware.device|grep FileName
echo "###### clonevm_host_2:"
govc object.collect -o -dump /DC0/vm/clonevm_host_2 config.hardware.device|grep FileName
echo "###### DC0_H0_VM0:"
govc object.collect -o -dump /DC0/vm/DC0_H0_VM0 config.hardware.device|grep FileName



output:
