摘要:
Systems and methods for copy and decrypt support for encrypted virtual machines are disclosed. An example method may include receiving, at a source host machine hosting a virtual machine (VM), a request to migrate the VM to a destination host machine, identifying a first page of memory of the VM on the source host machine for migration, write-protecting the first page, the first page of memory encrypted with a VM-specific encryption key, allocating a second page, executing a copy-and-reencrypt command using the first page and the second page as parameters for the copy-and-reencrypt command, the copy-and-reencrypt command to output the second page comprising contents of the first page re-encrypted with a migration key, and transmitting contents of the second page to the destination host machine.
