this makes it possible to give a storage for state saving, if one
wants to use a different storage than for snapshots or does not
want to save this info into the config

if a vm has the 'suspended' lock, we resume with the saved state
and remove the lock, the saved vmstate and the saved runningmachine
after the vm started

the idea is to have the same logic as with snapshots, but without
the snapshotting of the disks, and after saving the vm state (incl memory),
we hard shut off the guest.
this way the disks will not be touched anymore by the guest
to prevent any alteration of the vm (incl migration, hw changes, etc) we
add a config lock 'suspend'

we map scsiX to virtioscsiX/scsihwX when we use virtio-scsi-single to add
and iothread so we have to map it back when we delete an iothread, else the
parsing fails with
'invalid drive key: virtioscsi0'

qemu-img uses the qemu default initiator name 'iqn.2008-11.org.linux-kvm'
since we use the one of the host (/etc/iscsi/initiatorname.iscsi) when
using it with a running vm, we want to using it also when moving a disk
with qemu-img
to do that we have give qemu-img the image in as a full option string
this fixes the issue that we could not move an zfs-over-iscsi disk
without allowing the default qemu initiator

Adds the 'cicustom' option to specify either or both network and user
options as property strings. Their parameters are files in a snippets
storage (e.g. local:snippets/network.yaml). If one or both are specified
they are used instead of their respective generated configuration.
This allows the use of completely custom configurations and is also a
possible solution for bug #2068 by specifying a custom user file that
contains package_upgrade: false.
Tested with Ubuntu 18.10 and cloud-init 18.4.7

we also need to set the link status if the whole device changed,
otherwise a change of macaddress allows a network connection even
if link_down is set to 1

with such a shared memory device, a vm can share data with other
vms or with the host via memory
one of the use cases is looking-glass[1] with pci-passthrough, which copies
the guest fb to the host and you get a high-speed, low-latency
display client for the vm
on vm stop we delete the file again

This allows to set the wwn parameter for ide, sata and scsi disks in the VM
config and passes it to the qemu command on execution.
VirtIO Block does not supports this property, so exclude it from
there.

Space or newline after ':' is recognized as a mapping and as a result an
ipv6 ending in ':' is not parsed as a string. The solution is to quote
the address. For consistency all other addresses (including mac) are
quoted.

Currently Proxmox VE always deallocates HugePagesTLB
when starting a new machine and it makes it impossible
to preconfigure kernel /proc/cmdline with persistent allocation.
This change makes deallocation to prefer defaults set by /proc/cmdline,
by parsing the cmdline and respecting hugepages= and hugepagesz=.

commit 3c23aa808ccc946bad92d9bc63b6f833c61d0f52 tried to fix a issue
where after a stop mode backup a scope could still linger around, but
it actually removed the wrong check. If we want to remove a
lingering, not yet cleaned up, scope we need to check if said scope
exists not if a VM process is still running. While they are corelated
the scope will always get cleaned up _after_ it's processes are gone.
Should fix#2043, but as this is seemingly not that easy to fix one
for all I'll put the should as disclaimer here.

this adds a new config option for it, and executes it on four
points in time:
'pre-start'
'post-start'
'pre-stop'
'post-stop'
on pre-start we abort if the script fails
and pre-stop will not be called if the vm crashes or if
the vm gets powered off from inside the guest

a bit ago we had a control.in file which generated the control one,
so we added the build result to the list of git ignored files.
This is not the case anymore.

The qm CLI command offer the config and showcmd functions. Both of those
outputs may vary with respect to a given snapshot. This adds a switch
that shows the corresponding snapshot's config and command line.
The code needs a newer libpve-guest-common-perl, thus bumping the
dependency.

this patch allows the user to explicitely set a virtual vga,
even when using the 'x-vga' flag, this is sometimes necessary,
as some users need the 'x-vga' flag on the pci device,
but still want to use a virtual vga

commit 4530494bf9f3d45c4a405c53ef3688e641f6bd8e introduced an
regression with local disk migrations if the VM is online and thus
needs to live migrated and no target storage was passed as parameter.
We made the hack to write "1" to the targetstorage option in this
case obsolete, but it was still used on deciding if there are any
drives to mirror at all. Here it is enough to check if there are any
'online_local_volumes' because that hash gets only filled if we can
and are told to live mirror local disk on migrations anyway. Also,
we abort early if local disks are found and the 'with-local-disks'
option is not set.
