Steven Richman 9ea4c0c4d2 hypervisor: whpx: ignore unsupported msr writes 
Don't return an error from set_msr() if the msr is unsupported. This
restores the behavior before https://crrev.com/c/5436901.

Vcpu init sets MSR_IA32_MISC_ENABLE, which isn't available in the WHPX
API.

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.

Android Specific
