the not definedness check is unecessary here, since it does not
do anything then, and to check balloon twice is also not necessary
Signed-off-by: Dominik Csapak <d.csapak@proxmox.com>
Deleting the balloon config entry means resetting it to its
default. This means having a balloon device but not actually
doing any ballooning with it (iow. resetting the VM's
'balloon' value to its specified memory.).
Hotplugging a balloon device (coming from explicit '0' to
any other value (including deleting it)) is not possible.

To avoid potential cleanup & post-start actions to cause
unwanted processes (such as gpg-agent) to be started as part
of the scope, as the enter_systemd_scope() function causes
the current process to enter the scope.

cloning a vm means copying the current state, not the
state of 'some time in the future, when the vm is started again'
we should not copy the pending changes, which also fixes the
issue that we got a wrong pending change on the disks,net,smbios,etc.

(commit message reworked from original[1])
As a temporary workaround add always a pci.3 bridge so that if
virtio-scsi-single is used, either directly or indirectly if SCSI and
iothread is selected, the respective bridge is available:
> The case where we do miss the pci.3 bridge is when using
> virtio-scsi-single, regardless of whether io threads are enabled,
> because we always put those controllers on pci bus 3 (see
> QemuServer/PCI.pm)
-- [2]
A long term solution would be to always add those bridges dynamically
and just filter out the ones which are already inside the pve-q35.cfg
file .

when using q35 as machine type, there are nested pci-bridges,
but we only checked the first layer
this resulted in not being able to hotplug scsi devices,
because scsihw0 was deeper in the pci-bridge construct, we did not see
it and tried to add it (which fails of course)
this patch checks all bridges, regardless how deeply nested they are

it is not necessary to check the romfile of the running vm
for .pxe machine types, since the machine type itself is not
hot-pluggable

With QEMU 2.10 the serial parameter of the -drive command line option
was deprecated [1], so move the logic which adds this parameter now
to the -drive analogue -device CLI option.
Features marked deprecated will continue to work for two releases[2],
so we need to switch over before 2.12, AFAICT.

Modern noVNC does not needs this anymore, actually things may get
worse if it's used. E.g., when one sets 'de' and the VM locale is
'de' you may get a 'ĸ' (unicode kra) if you want to send an ampersand
character through pressing SHIFT + 6.
Qemus manual pages confirms that this is most times not needed
anymore:
> -k language
> Use keyboard layout language (for example "fr" for
> French). This option is only needed where it is not
> easy to get raw PC keycodes (e.g. on Macs, with some
> X11 servers or with a VNC or curses display). You don't
> normally need to use it on PC/Linux or PC/Windows
> hosts.

The git history of this is not immediately obvious due to
the date of the cloud init patches, but the removal of this

We introduced our QMP socket with commit
c971c4f2213524f27125f558978a428b53628f34 (29.05.2012)
Already tried to remove this with commit
7b7c6d1b5dcee25e1194d4b8a0219bd5c31a5639 (13.07.2012)
But reverted that to allow migration of VMs still using the old
montior to ones which already switched over to the new QMP one,
in commit dab36e1ee924be0efab3f85937c23910b456f4b9 (17.08.2012)
see bug #242 for reference
This was all done and released in PVE 2.2, as no migration through
nodes differing more than one major version is possible we can
finally remove this code for good.

We don't leave this up to cloud-init as we don't want
un-hashed values at all in our configs.
Signed-off-by: Wolfgang Bumiller <w.bumiller@proxmox.com>
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.
