Very good post about recovering vmx from vmware.log
http://www.vi-toolkit.com/wiki/index.php/Recover_vmx_from_log_file
How to identify duplicate MACs.
Vcenter takes care of not allocating duplicate MACs, but it might be worthwhile
to check it, if you are merging two Vcenters or adding hosts from standalone to a vcenter. This could happen if you have UCS ( allocation could happen from a MAC pool
or ESXi holding previous service profile's mac in /etc/vmware/esxi.conf)
From Switch (N5K), show mac-address-table and two veths should not be having same MAC address even if they are different vlan.
From ESX perspective.
vim-cmd hostsvc/datastore/listsummary|egrep "url|name"
for vmid in `vim-cmd vmsvc/getallvms|awk '{print $1}'|grep -v Vmid`;do echo $vmid ;vim-cmd vmsvc/device.getdevices $vmid|grep macAddress;done | |sort| uniq -c|sort| grep -v "^ 1"
Also you can look at UUID
