For savevm, one can't do a:

It turns out that it's legal to create a VM with RAMBlocks that aren't
a multiple of the pagesize in use; e.g. a 1025M main memory using
2M host pages. That breaks postcopy's atomic placement of pages,
so disallow it.

Unfortunately it's legal to create a VM with a RAM size that's
not a multiple of the underlying host page or huge page size.
Recently I'd changed things to always send host sized pages,
and that breaks if we have say a 1025MB guest on 2MB hugepages.
Unfortunately we can't just make that illegal since it would break
migration from/to existing oddly configured VMs.
Symptom: qemu-system-x86_64: Illegal RAM offset 40100000
as it transmits the fraction of the hugepage after the end
of the RAMBlock (may also cause a crash on the source
- possibly due to clearing bits after the bitmap)

According to section 2.1.2 of the virtio-1 specification:
"The device SHOULD set DEVICE_NEEDS_RESET when it enters an error state that
a reset is needed. If DRIVER_OK is set, after it sets DEVICE_NEEDS_RESET,
the device MUST send a device configuration change notification to the
driver."
Commit "f5ed36635d8f virtio: stop virtqueue processing if device is broken"
introduced a virtio_error() call that just does that:
- internally mark the device as broken
- set the DEVICE_NEEDS_RESET bit in the status
- send a configuration change notification
Unfortunately, virtio_notify_vector(), called by virtio_notify_config(),
returns right away when the device is marked as broken and the notification
isn't sent in this case.
The spec doesn't say whether a broken device can send notifications
in other situations or not. But since the driver isn't supposed to do
anything but to reset the device, it makes sense to keep the check in
virtio_notify_config().
Marking the device as broken AFTER the configuration change notification was
sent is enough to fix the issue.

fw_cfg won't work with -device, as:
* fw_cfg_init1() won't get called for the device;
* The device won't appear at /machine/fw_cfg, and won't work with
the -fw_cfg command-line option.
Remove the user_creatable flag from the device class.

always fail with "Only 1 ioapics allowed". Remove the

kvmclock should be used by guests only when the appropriate CPUID
feature flags are set on the VCPU, and it is automatically
created by kvmclock_create() when those feature flags are set.
This means creating a kvmclock device using -device is useless.
Remove user_creatable from its device class.
