500d91311f hypervisor: aarch64: kvm: use concrete KvmVm type where possible 
The code was moved from the vmm crate to the hypervisor crate. After the
move it is trivially obvious that it only works with KVM. Use concrete
types where possible.

This allows us to drop create_device from the Vm trait.

No functional change intended.

45fbf840db hypervisor, vmm: move away from CpuId type 
CpuId is an alias type for the flexible array structure type over
CpuIdEntry. The type itself and the type of the element in the array
portion are tied to the underlying hypervisor.

Switch to using CpuIdEntry slice or vector directly. The construction of
CpuId type is left to hypervisors.

This allows us to decouple CpuIdEntry from hypervisors more easily.

No functional change intended.

This return type is not a problem since this function is implemented

mshv-specific type with `u32`.

507912385a vmm: Ensure that PIO and MMIO exits complete before pausing 
As per this kernel documentation:

      For KVM_EXIT_IO, KVM_EXIT_MMIO, KVM_EXIT_OSI, KVM_EXIT_PAPR, KVM_EXIT_XEN,
      KVM_EXIT_EPR, KVM_EXIT_X86_RDMSR and KVM_EXIT_X86_WRMSR the corresponding
      operations are complete (and guest state is consistent) only after userspace
      has re-entered the kernel with KVM_RUN.  The kernel side will first finish
      incomplete operations and then check for pending signals.

      The pending state of the operation is not preserved in state which is
      visible to userspace, thus userspace should ensure that the operation is
      completed before performing a live migration.  Userspace can re-enter the
      guest with an unmasked signal pending or with the immediate_exit field set
      to complete pending operations without allowing any further instructions
      to be executed.

Since we capture the state as part of the pause and override it as part
of the resume we must ensure the state is consistent otherwise we will
lose the results of the MMIO or PIO operation that caused the exit from
which we paused.

Fixes: #3658

658658e76c hypervisor: kvm: Ignore -EINVAL from KVM_KVMCLOCK_CTRL ioctl() 
If the guest hasn't initialised a PV clock then the KVM_KVMCLOCK_CTRL
ioctl will return -EINVAL. Therefore if running in the firmware or an OS
that doesn't use the PV clock then we should ignore that error

Tested by migrating a VM that has not yet booted into the Linux kernel
(just in firmware) by specifying no disk image:

e.g. target/debug/cloud-hypervisor --kernel ~/workloads/hypervisor-fw --api-socket /tmp/api --serial tty --console off

Fixes: #3586

7f0e7d19a6 Revert "build: bump vm-memory from 0.6.0 to 0.7.0" 
This was causing some issues because of the use of 2 different versions
for the vm-memmory crate. We'll wait for all dependencies to be properly
resolved before we move to 0.7.0.

This reverts commit 76b6c62d07.

81895b9b40 hypervisor: Implement start/stop_dirty_log for MSHV 
This patch modify the existing live migration code
to support MSHV. Adds couple of new functions to enable
and disable dirty page tracking. Add missing IOCTL
to the seccomp rules for live migration.
Adds necessary flags for MSHV.
This changes don't affect KVM functionality at all.

In order to get better performance it is good to
enable dirty page tracking when we start live migration
and disable it when the migration is done.

fdecba6958 hypervisor: MSHV needs gpa to retrieve dirty logs 
Right now, get_dirty_log API has two parameters,
slot and memory_size.
MSHV needs gpa to retrieve the page states. GPA is
needed as MSHV returns the state base on PFN.

e7c9954dc1 hypervisor, vmm: Abstract the interfaces to start/stop dirty log 
Following KVM interfaces, the `hypervisor` crate now provides interfaces
to start/stop the dirty pages logging on a per region basis, and asks
its users (e.g. the `vmm` crate) to iterate over the regions that needs
dirty pages log. MSHV only has a global control to start/stop dirty
pages log on all regions at once.

This patch refactors related APIs from the `hypervisor` crate to provide
a global control to start/stop dirty pages log (following MSHV's
behaviors), and keeps tracking the regions need dirty pages log for
KVM. It avoids leaking hypervisor-specific behaviors out of the
`hypervisor` crate.

5e0d498582 hypervisor, vmm: Add dynamic control of logging dirty pages 
This patch extends slightly the current live-migration code path with
the ability to dynamically start and stop logging dirty-pages, which
relies on two new methods added to the `hypervisor::vm::Vm` Trait. This
patch also contains a complete implementation of the two new methods
based on `kvm` and placeholders for `mshv` in the `hypervisor` crate.

Fixes: #2858
