If you wish to share a virtual image, and the virtual images does NOT allow re-assignment of IP addresses, this can be a challenge.
Fortunately, there is a method to address.
If you have moved or copied a vmware image (snapshot copy), the generate MAC address within the *.vmx configuration file may also change. When you restart your moved/copied image, the IP address assigned by Vmware DHCP services will provide a new IP address.
One method is to roll-back the MAC address to the older version, if this is your own HOST OS vmware system.
If this is a copy to share with others, it will be necessary for the user to update their own (NAT) to the same IP range, or setup a new HOST-ONLY with the same IP range.
To force the SAME IP address to be used, the following configuration files may be edited for Vmware Workstation/Player. Vmware Fusion has similar files with different names.
If you find this useful, please let me know.
I am using this process for the CA Identity Suite virtual application solution; when I build "sandbox" environments for customers to share.
