Problem Description
During a Full Hyper-V VM restore operation, the restore fails with the error code HYPERV11. The error indicates that the assigned virtual memory size for the target virtual machine exceeds the maximum limit permitted by the Hyper-V host or its current configuration.
Traceback
The following error message is captured in the logs during the restore failure:
SyncError: Memory virtual quantity above maximum. (#10009000b : 32768) (Error Code: HYPERV11)
Cause
The restore process is attempting to provision 32 GB (32,768 MB) of memory to the virtual machine. However, this allocation exceeds the maximum supported memory limit configured on the destination Hyper-V host, or it surpasses the available physical resources.
Resolution
Follow these steps to adjust the host configuration or VM settings before retrying the restore:
Log in to the destination Hyper-V host where the restore is being attempted.
Verify host constraints: Check the host's available physical memory and any configured virtual memory provisioning constraints.
Adjust memory allocation: Ensure the target VM's memory settings are adjusted to align with the host's physical limitations and policies.
Retry the restore: Once the memory constraints are resolved or the host resources are freed up, initiate the full restore operation again.
