- Don't register a VM for DHCP on wireless.
- When copying or backing up a VM image:
- Make sure the VM is powered off.
- Do not copy the lockfile directory (the only subdirectory that ends in ".lck").
- When restoring from backup use move, not copy. This prevents issues with duplicate Mac Addresses on the same network.
- Treat each VM as a standalone computer for security purposes. Install virus scanning software. Take regular OS updates.
- Networking: use NAT Networking. This should be the default setting for your virtual machines.
- Carefully plan your disk allocations. Do not over-allocate your disk. It is dangerous to tell VMware to make images that, if they all grew to their full size, would take up more disk space than you have free. If this happens, VMware may pop up an alert warning you when you're about to use up more space than you have. That would give you a chance to free up disk space or exit cleanly. We don't recommend relying on the warning. There's no guarantee it will appear before bad things (data loss or corruption) happen.
Backups
The importance of backing up your data cannot be stressed enough. Virtual machines are at just as much risk, if not more, for data loss due to hardware failure, file corruption, system compromise, and other events. If data loss happens, a backup can make a world of difference in recovering from such an event. How you use your virtual machine will determine the best way to do backups for your virtual machines.
