Xen (like other) virtual machines allows VMs to be saved and resumed. Xen on Debian Lenny, for instance, is configured to save and resume virtual machines on Dom0 restarts.
Is it possible to have this behavior enabled, but prevent certain VMs from being saved? Reason behind this is that I have some VMs with client data that are using
cryptsetup-luks to store the data encrypted and I'd rather not have the encryption key being paged out to the memory save file.
Or is encrypting the storage area of the memory save files the only way around this situation?
