We might want to explore [`sysinfo`](https://docs.rs/sysinfo) for getting CPU frequencies from the OS instead of parsing CPUID (x86 only) ourselves. See [hermit-os/kernel/xtask/src/ci/qemu.rs#L283-L291](https://github.com/hermit-os/kernel/blob/4ce7439440eb19a13a88f65d61ef23debecac6f5/xtask/src/ci/qemu.rs#L283-L291) for example.

During the unikernel meet-up, I just tried uhyve in a Linux VirtualBox VM (with nested virtualization enabled) and I get ``` cfinck@kubuntuvm:~/unikernel-meetup/hands-on-session/hello-hermit$ RUST_BACKTRACE=1 uhyve -v target/x86_64-unknown-hermit/debug/hello-hermit thread 'main' panicked at...

Unsoundness in the implementation of several functions

### The source of unsoundness https://github.com/hermit-os/uhyve/blob/419435763d826e4578d6d234549cce9a37b11e4c/src/linux/virtqueue.rs#L51-L54 Hi, we consider that `ring_elem` is unsound because it allows `u8` pointer cast to arbitrary pointer types and dereference the types. It can break...
