George Burgess IV cdaf2bd57f kvm: add mut to mutable binding 
`KVM_CREATE_DEVICE` turns into an `ioctl` that mutates `device`, so
`device` must be declared as `mut`. Rust 1.78 forwards `device.fd == 0`
to the `Ok(...)` return, which made this incorrect code more visible.

BUG=b:361302729
TEST=Built & ran with Rust 1.78.

Hypervisor Support

Multiple hypervisor backends are supported. See Advanced Usage for overriding the default backend.

Hypervisors added to crosvm must meet the following requirements:

  • Hypervisor code must be buildable in crosvm upstream.
    • Within reason, crosvm maintainers will ensure the hypervisor's code continues to build.
  • Hypervisors are not required to be tested upstream.
    • We can't require testing upstream because some hypervisors require specialized hardware.
    • When not tested upstream, the hypervisor's maintainers are expected to test it downstream. If a change to crosvm breaks something downstream, then the hypervisor's maintainers are expected to supply the fix and can't expect a revert of the culprit change to be accepted upstream.

KVM

  • Platforms: Linux
  • Tested upstream: yes

KVM is crosvm's preferred hypervisor for Linux.
