96209e7a16 vmm: Remove the explicit call to 'Snapshottable:restore()' 
The restore path of MemoryManager is handled specially without
implementing a `Snapshottable:restore()`. Removing the explicit call to
it along the migration code path to avoid confusions.

958ef69295 tests: Rely on wtmp (the login records) to count reboot times 
The systemd journal has a known issue of generating large size logs[1],
which makes it unreliable as a source for retrieving system
information, such as for counting reboot times. This is particularly
problematic on disk-constrained systems, like the VMs we launched for
our integration tests, where the disk size is normally 2GB. By default,
the systemd journal has a size limit of 10% of the size of the
underlying file system (e.g. around 200MB for the VMs of our integration
tests), which would remove archived journal files on demand.

A better alternative to count reboot times is based on information from
`wtmp` (e.g. the login records) which is much more concise and can be
accessed via the `last` command.

2a45e44bda qcow: Fix the calculation of the number of clusters for L1 table 
In function create_for_size(), when calculating the number
of clusters for the L1 table, it incorrectly divides the total number of
entries in the L1 table by the cluster size. In fact, it should be
divided by the number of entries/addresses that can fit into a cluster.

099cdd2af8 virtio-devices, vmm: vdpa: Implement live migration support 
Vdpa now implements the Migratable trait, which allows the device to be
added to the DeviceTree and therefore allows live migrating any vDPA
device that supports being suspended.

Given a vDPA device can't be resumed from a suspended state without
having to reset everything, we don't support pause/resume for a vDPA
device, as well as snapshot/restore (which requires resume to be
supported).

In order for the migration to work locally, reusing the same device on
the same host machine, the vhost-vdpa handler is dropped after the
snapshot has been performed, which allows the destination VM to open the
device without any conflict about the device being busy.

2b150ac2ea pci, virtio-devices: Restore proper BAR type 
When restoring a VM, the BAR type can be found directly from the
snapshot resources. It is more reliable than the previous method which
was using self.use_64bit_bar from VirtioPciDevice because at the time
the BARs are allocated, the VirtioDevice hasn't been restored yet,
meaning the way to determine the value of use_64bit_bar is wrong for a
device like vDPA. At this time, the device type is not known and relying
on the stored resources is the only reliable way.

89a2562c5a pci: Optimise MSI-X table programming 
With an updated Linux kernel the kernel reprograms the same table entry
in the MSI-X table multiple times. Fortunately it does so with entry
masked (the default.)

The costly part of MSI-X table reprogramming is going out to the host
kernel to update the GSI routing entries. This change makes three
optimisations.

1. If the table entry is unchanged: skip handking updates
2. Only update the GSI routing table if the table entry is unmasked
   (this skips extra calls to the ioctl() for reprogramming the
    entries.)
3. Only generate a message on entry unmasking if the global MSI-X enable
   bit is set.

Fixes: #4273
