Hello everyone,

XCP-NG 8.2.1 here. Recently, I encountered issues with SR network connectivity (10Gb iSCSI), which caused a few virtual machines (VMs) to stop and subsequently fail to start, displaying the well-known error message: FAILED_TO_START_EMULATOR. While restarting the toolstack or the host are proven solutions, I would like to suggest two additional approaches:

1. If you have at least two hosts in the same pool, attempt to start the VM on another host.
2. Create a snapshot of the VM and immediately revert to it. Then try to start the VM again. This should resolve the issue.
