305e095d15 vmm: device_manager: Invert pci_id_list HashMap
In anticipation for further factorization, the pci_id_list is now a
hashmap of PCI b/d/f leading to each device name.

62aaccee28 vmm: Device name verification based on DeviceTree
Instead of relying on a PCI specific device list, we use the DeviceTree
as a reference to determine if a device name is already in use or not.

13724dbd22 main: Remove messages from startup
Remove the startup message containing incomplete VM configuration
details. It's a bit unusual for a tool such as Cloud Hypervisor to print
those kind of details which are a direct representation of the command

f685f0e0b2 vm-virtio: initialize MSI-X vectors with VIRTIO_MSI_NO_VECTOR
In case of the virtio frontend driver doesn't need interupts for
certain queue event, it may explicitly write VIRTIO_MSI_NO_VECTOR
to the virtio common configuration, or it may doesn't configure
the event type vector at all.

This patch initializes both MSI-X configuration vector and queue vector
with VIRTIO_MSI_NO_VECTOR, so that the backend drivers won't trigger
unexpected interrupts to the guest.

afc83582be aarch64: Enable IRQ routing for legacy devices
On AArch64, interrupt controller (GIC) is emulated by KVM. VMM need to
set IRQ routing for devices, including legacy ones.

Before this commit, IRQ routing was only set for MSI. Legacy routing
entries of type KVM_IRQ_ROUTING_IRQCHIP were missing. That is way legacy
devices (like serial device ttyS0) does not work.

The setting of X86 IRQ routing entries are not impacted.

In case CONFIGURE_MEM_SLOTS is not supported by the backend (feature not
