I have a Window 8.1 host trying to start a virtual machine through Hyper-V. The VM is configure to use 10GB of RAM, I have 16GB, it should start but it doesn't.
Instead I get the message
'{VM NAME}' could not initialise.
Not Enough Memory in the system to start the virtual machine {VM NAME}
The host has 16GB RAM, of which only 4.8GB is in use. This leaves at least 11GB available for Hyper-V to use. Except it can't.
To be more accurate, task manager reports the following memory situation:-
- In use - 4.8GB
- Available - 11.0 GB
- Committed - 7.5/21.9GB
- Cached - 10.8GB
- Paged Pool - 592MB
- Non-Paged pool - 309MB
I understand that I currently have 10.8GB of "Standby" memory. But this should be released if Hyper-V asks for it right?
If I reboot then immediately ask Hyper-V to start the machine, it works, but I have to be quick because the standby memory gets filled pretty quickly.
Is this normal? Is there a way to empty the standby memory and get it back, so that I can start my VM without having to reboot the host?
