Yes there's no reason to forbid that, it's just that we're not adding new tests but we can potentially change any future use_shmem to not test shmem anymore.. instead we test something we don't suggest users to use.. The only concern is a small /dev/shm mount, am I right? Would it work if switch to memory-backend-memfd,shared=on? Thanks, -- Peter Xu
