Restoring a VM from a Snapshot

  1. Use your hypervisor tools to restore the VM from the snapshot.
  2. For Linux, log into the VM as root. For Windows, log in as a System Administrator and open a Command Prompt or start Windows PowerShell.

  3. Enter the hcl status command and determine if the grace period has expired.

  4. If required, re-authenticate the VM with Cryptographic Security Platform Vault for VM Encryption as described in Re-Authenticating a Standard VM or Re-Authenticating a VM with an Encrypted Root Device or Boot Disk.

  5. After the VM has been authenticated, re-synchronize the device using the hcl devicesync reason command, where reason is a user-defined reason for the re-sync. This text string is logged in the Cryptographic Security Platform Vault for VM Encryption audit log and added to the alert message sent during sync processing.

    # hcl devicesync "restored hq-4-linux from snapshot"

  6. Make sure the device list in configuration file on the VM is accurate using the hcl updateconfig command. This updates the list in real time without requiring a VM reboot.

    # hcl updateconfig
