On arm we start off with a pcie bridge pcie.0. We need a
keyboard in addition to the tablet device, and we need to
connect both to an 'ehci' controller.
To do all this, we also pass the $arch variable through a
whole lot of function calls to ultimately also adapt the
hotplug code to take care of the new keyboard device.

SLAAC previously set 'auto' which is not supported by nocloud network
config. On an up-to-date Ubuntu this should work as it uses 'dhcp' for
both dhcp and SLAAC. For others it was invalid anyway.

we change 'vga' to a property string and add a 'memory' property
with this, the user can better control the memory given to the virtual
gpu, this is especially useful for spice/qxl since high resolutions need
more memory

this imitates the qemu-guest-agent interface
with an 'exec' api call which returns a pid
and an 'exec-status' api call which takes a pid
the command for the exec call is given as an 'alist'
which means that when using we have to give the 'command'
parameter multiple times e.g.
pvesh create <...>/exec --command ls --command '-lha' --command '/home/user'
so that we avoid having to deal with shell escaping etc.

we have '$conf, $vmid' elsewhere for cloudinit, this was the only
function which had them in reverse

Leaving files in /tmp was mostly useful for debugging
purposes initially. Also /tmp is a rather insecure option
for this for a final version, so use
/run/pve/cloudinit/$vmid, and move the file writing into
commit_cloudinit_disk() which now takes a hash mapping file
paths to contents, to not duplicate the temp-file logic for
the different citypes.

With configdrives we end up with the /etc/network/interfaces
file containing the interface names we use on the disk, ie.
eth0/eth1/..., which doesn't work on systems which do not
use this name.
With the 'nocloud' image type we can provide a
network-config in yaml which matches mac addresses. Ideally
we'd use version 2, but debian stretch ships with a too old
cloud-init for this, so for now we're writing version 1.

We now have a patch on top of qemu to allow 'qemu-img dd'
to read from stdin when specifying input and output sizes,
as well as a way to tell it that the size of the source is
not known.

perls 'local' must be either used in front of each $SIG{...}
assignments or they must be put in a list, else it affects only the
first variable and the rest are *not* in local context.
In all cases the global signal handlers we overwrote were in cli programs or
forked workers, not in daemons.
Each disk passed as paramater is add as 'unused[n]' in the vm.conf
(the default) or ide[n]|scsi[n]|sata[n]
We rely on qemu-img(1) convert heuristics to detect the file type,
as this works in most case.
foreach_dimm() provides a guest numa node index, when used
in conjunction with the guest-to-host numa node topology
mapping one has to make sure that the correct host-side
indices are used.
This covers situations where the user defines a numaX with
hostnodes=Y with Y != X.
For instance:
cores: 2
hotplug: disk,network,cpu,memory
hugepages: 2
memory: 2048
numa: 1
numa1: memory=512,hostnodes=0,cpus=0-1,policy=bind
numa2: memory=512,hostnodes=0,cpus=2-3,policy=bind
Both numa IDs 1 and 2 passed by foreach_dimm() have to be
mapped to host node 0.
Note that this also reverses the foreach_reverse_dimm() numa
node numbering as the current code, while walking sizes
backwards, walked the numa IDs inside each size forward,
which makes more sense. (Memory hot-unplug is still working
with this.)
vm configuration
----------------
hugepages: (any|2|1024)
any: we'll try to allocate 1GB hugepage if possible, if not we use 2MB hugepage
2: we want to use 2MB hugepage
1024: we want to use 1GB hugepage. (memory need to be multiple of 1GB in this case)
optionnal host configuration for 1GB hugepages
----------------------------------------------
1GB hugepages can be allocated at boot if user want it.
hugepages need to be contiguous, so sometime it's not possible to reserve them on the fly
/etc/default/grub : GRUB_CMDLINE_LINUX_DEFAULT="quiet hugepagesz=1G hugepages=x"
