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.

f84ddedb1a hypervisor, vmm: introduce trait functions for aarch64 PMU 
The original code uses kvm_device_attr directly outside of the
hyeprvisor crate. That leaks hypervisor details.

No functional change intended.

5f98710471 virtio-devices: vhost-user: Stop the vrings on a virtio reset 
Whenever a virtio reset happens, the vhost-user backend should be
notified that the vring should be stopped. This is performed by calling
GET_VRING_BASE on the appropriate queue indexes.

613c60fc6f virtio-devices: vhost-user: Enable correct queue indexes 
Rather than relying on the amount of queues to enable or disable the
queue that have been activated, we rely on the actual queue indexes
provided through the tuple including the queue index, the Queue and the
EventFd. By storing the list of indexes, we simplify the code and also
make it more accurate in case some queues aren't activated.

3f62a172b2 virtio-devices: Pass a list of tuples for virtqueues 
Instead of passing separately a list of Queues and the equivalent list
of EventFds, we consolidate these two through a tuple along with the
queue index.

The queue index can be very useful if looking for the actual index
related to the queue, no matter if other queues have been enabled or
not.

It's also convenient to have the EventFd associated with the Queue so
that we don't have to carry two lists with the same amount of items.

e1a63822fa virtio-devices: fs: Reduce minimal amount of enabled queues to 1 
It's not mandatory for the virtio-fs driver to enable all virtqueues
provided by the backend since all it needs is one request queue to work
correctly. Therefore we lower the minimal amount of enabled queues to 1.

ec27e0ee82 tests: Fix test_virtio_balloon_deflate_on_oom() 
It might sometimes take a few seconds for the guest to trigger the OOM
and report it back to the host. That's why this patch adds some sleep
time between the command in the guest supposedly triggering the OOM and
the check of the balloon size from the host.

Fixes #4336

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.
