SIRIS, ALTO, and NAS: Troubleshooting slow virtual machine boot up

Follow

Issue

Virtual machines hosted on a Datto SIRIS can sometimes experience a slow boot process. This article outlines the steps to address this issue.

This article only applies to Windows VMs configured for live network connectivity in a disaster recovery environment.

Environment

  • Datto SIRIS

Cause

Non-Microsoft services enabled in msconfig.

Some services that are known to cause slow boot times:

  • Dell Server Management Tools
  • HP Server Management Tools
  • VMware Tools

Your device can also boot slowly if too many services are starting during the boot process.

Resolution

1. Boot or reboot the virtual machine into Safe Mode (external link). The boot process starts very quickly. If you miss the boot screen, reboot the VM to and try again.

2. Once the virtual machine boots into Safe Mode, access msconfig by clicking Start → Run → msconfig.

3. Choose the Services tab, check the "Hide all Microsoft services" box, and then click the Disable all button.

The "VirtualBox Guest Additions service" used for virtual drivers and is installed on the production machine during the ShadowSnap Agent installation will not be impacted by these steps. It will still start when you reboot the virtual machine.

4. Reboot the virtual machine. The machine should now boot into the virtual environment at normal speed with live networking enabled.

5. Re-enable ShadowProtect Service, StorageCraft Raw Agent, and StorageCraft Shadow Copy Provider so that the next backup can complete properly.
