A. If you have a VM that's frozen, or just any VM or VM snapshot, and you want a memory dump, you can use the vm2dmp.exe utility that's provided by Microsoft. To dump out a running VM's memory, use the command

vm2dmp.exe -vm <Virtual Machine name> -dmp <dump file name and location>

You can also get dumps from VM snapshots and state files by using the -snap and -vsv switches, as described on the download page.
