qemu-system-x86_64: "Bad system call"

[KedalionDaimon]

Trying to run QEMU results in "Bad system call" and return to the iSH shell.

specifically, even this triggers it:

qemu-system-x86_64 --help

... and any attempts to run any virtual machine, of course, fail, too.

EDIT: qemu-system-aarch64 and qemu-system-i386 behave the same way, talking of an iPhone 15 running iOS 17.4.1.

I tried that too sometime before, I think the issue lies in the reason that iSH has a lot of limitations.

Qemu system uses pretty complicated vm and interrupt handlers in the kernel (the kvm subsystem). Since ish reimplements kernel features we would have to also implement them which would take ages. We still have bugs in simple syscalls that handle linking and UDP sockets. It would be nice to have but realistically speaking pretty far in the future.

Anyway cheers, I suggest you run your vms on a different machine and access them over ssh.
