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.

Hypercall register needs to be saved and restored for
TLB flush and IPI synthetic features enablement.
Enabling these two synthetic features improves
guest performance.

When the synthetic interrupt controller is enabled, an extra set of MSRs
must be stored in case of migration. There was one MSR missing in the
list, HV_X64_MSR_SINT14 corresponding to the 15th interrupt source from
the synthetic interrupt controller.

Updating kvm-ioctls from 0.9.0 to 0.10.0 now that Cloud Hypervisor
relies on kvm-bindings 0.5.0.
Signed-off-by: Sebastien Boeuf <sebastien.boeuf@intel.com>
Update the kvm-bindings dependency so that Cloud Hypervisor now depends
on the version 0.5.0, which is based on Linux kernel v5.13.0. We still
have to rely on a forked version to be able to serialize all the KVM
structures we need.

The rust-vmm crates we're pulling from git have renamed their main
branches. We need to update the branch names we're giving to Cargo,
or people who don't have these dependencies cached will get errors
like this when trying to build:
error: failed to get `vm-fdt` as a dependency of package `arch v0.1.0 (/home/src/cloud-hypervisor/arch)`
Caused by:

Definition of kvm_tdx_init_vm used by INIT_VM has been updated in latest
kernel, needing an update on the Cloud Hypervisor side as well.
Update structure TdxInitVm to fit this change and avoid -EINVAL to be
returned by the kernel.

This doesn't really affect the build as we ship a Cargo.lock with fixed
versions in. However for clarity it makes sense to use fixed versions
throughout and let dependabot update them.

Moving the MSHV crate form Cloud Hypervisor to rust-vmm
is done. This patch update the MSHV referent to rust-vmm

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.

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.

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.

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.

We need a dedicated function to enable the SGX attribute capability
through the Hypervisor abstraction.
Signed-off-by: Sebastien Boeuf <sebastien.boeuf@intel.com>
Previously the same function was used to both create and remove regions.
This worked on KVM because it uses size 0 to indicate removal.
MSHV has two calls -- one for creation and one for removal. It also
requires having the size field available because it is not slot based.
Split set_user_memory_region to {create/remove}_user_memory_region. For
KVM they still use set_user_memory_region underneath, but for MSHV they
map to different functions.
This fixes user memory region removal on MSHV.
