The purpose of that step is to make sure each commit builds. The `check`
command is much faster for that purpose.
On my 32-core machine `cargo check --all` takes around 25 seconds while
`cargo build --all` takes around 35 seconds, so that's quite a bit of
time saving there.

Since all unit and integration tests are run inside containers because
they are called from dev_cli.sh, they always run as root. That's why
both unit and integration scripts can be simplified as they don't need
to apply specific capabilities and run cargo tests in a dedicated 'kvm'
group.

The Cloud-Hypervisor fork of the vhost crate contains one small
additional patch compared to the rust-vmm upstream version, meant for
increasing the connection timeout.
This patch is intended to be merged in order to check if it helps our CI
fixing the vhost-user-blk flakes that we've been observing recently.
If it fixes it, we'll submit a similar patch upstream and switch back to
the upstream vhost crate, otherwise we'll simply switch back to the
upstream crate, discarding this patch.

Because of the PCI refactoring that happened in the previous commit
d793cc4da3, the ability to fully remove a
PCI device was altered.
The refactoring was correct, but the usage of a generic function to pass
the same reference for both BusDevice, PciDevice and Any + Send + Sync
causes the Arc::ptr_eq() function to behave differently than expected,
as it does not match the references later in the code. That means we
were not able to remove the device reference from the MMIO and/or PIO
buses, which was leading to some bus range overlapping error once we
were trying to add a device again to the previous range that should have
been removed.

Run loop in hypervisor needs a callback mechanism to access resources
like guest memory, mmio, pio etc.
VmmOps trait is introduced here, which is implemented by vmm module.
While handling vcpuexits in run loop, this trait allows hypervisor
module access to the above mentioned resources via callbacks.

The PMEM support has an option called "discard_writes" which when true
will prevent changes to the device from hitting the backing file. This
is trying to be the equivalent of "readonly" support of the block
device.
Previously the memory of the device was marked as KVM_READONLY. This
resulted in a trap when the guest attempted to write to it resulting a
VM exit (and recently a warning). This has a very detrimental effect on
the performance so instead make "discard_writes" truly CoW by mapping
the memory as `PROT_READ | PROT_WRITE` and using `MAP_PRIVATE` to
establish the CoW mapping.

When all refblocks are consumed, the loop looking for the first free
cluster would access the element at refcounts[refcounts.len()], which is
out of bounds. Modify the free cluster search loop to check that the
index is in bounds before accessing it.

When the destination mode is physical, the destination field should
only be defined through bits 56-59, as defined in the IOAPIC spec. But
from the APIC specification, the APIC ID is always defined on 8 bits no
matter which destination mode is selected. That's why we always retrieve
the destination field based on bits 56-63.

to irq_fd. This is done similarly to the enable and disable helper
functions.
Also drop the pub keyword from InterruptRoute fields. It is not needed

In order to support both amd64 and arm64, we rely on the TARGETARCH
variable that is passed from the docker buildx command, based on the
platform used to build the container image.
There is no way to rely directly on $(uname -m) to assign a variable
with the correct x86_64 or aarch64 values we're looking for. Both ENV
and ARG don't evaluate the command, which means they see it as a simple
string. Using RUN is the only way to evaluate a command.
