How To Fix VIRT426 - Target Memory Buffer

SAP Error Message - Details

• Message type: E = Error

• Message class: VIRT - Virtualization Monitoring

• Message number: 426

• Message text: Target Memory Buffer

What causes this issue?

On Hyper-V: the number shows the portion (in percent) of the Memory
Demand value that the hypervisor should add as memory buffer to the VM
if there are sufficient physical memory resources available on the
virtualization host. So, the hypervisor tries to assign an amount of
memory (Target Memory) to the VM according the formula:
Target Memory = Memory Demand + (Memory Demand * Target Memory
Buffer)/100
However, the Target Memory is not guaranteed when the virtualization
host is under memory pressure.
This value is valid with activated Dynamic Memory only.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
