assigned 1500GB of Memory

Hello,

Question Background:

When I assigned 1500GB of memory to a virtual machine and tried to start it,
I got the following error.
+++++++++++++
VM {xxxx} is down with error. Exit message:
internal error: qemu unexpectedly closed the monitor:
2025-03-21T08:41:35.731777Z qemu-system-x86_64: -numa node,nodeid=0,cpus=0-119,mem=1024000: warning: Parameter -numa node,mem is deprecated, use -numa node,memdev instead
2025-03-21T08:41:35.767633Z qemu-system-x86_64: Address space limit 0xffffffffff < 0x1027fffffff phys-bits too low (40).
+++++++++++++

・If you reduce the allocated capacity to about 900GB, it will start.

Questions:
Is there any way to avoid the above error and start the virtual machine with 1500GB?
