Virtual Machine and GDB

[teawater]

Sorry, I told about ARCH because I think you were the people that ask
the same question in CLF.
He told that his VM has a new instruction set. So I think the ARCH of
his VM is not support by GDB.
If the ARCH of your VM is supported by GDB, you will not need to porting it.

This doc is very clear.

I think if your stub on VM support GDBRSP write memory command M, you
can use GDB command load do it.
