The 'migrate_speed' can be set in the VM config. Additionally the 'migrate'
bwlimit from datacenter.cfg (storage-specific limits play no role for

the speed. Take the lower of the two.

commit 4530494bf9 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.
This was reported at:

the check for targetstorage in:
if ($self->{running} && $self->{opts}->{targetstorage} && $local_volumes->{$volid}->{ref} eq 'config') {
was obsolete, as we always set the tragetstorage opts variable to '1'
in a broader "use same sid for remote local" check above.
So removing it leads to the same if truthtable but fixes the
check if we should fallback to the volume's SID if targetstorage is
not set, as else it seemed to be always set, and '1' is naturally not
a correct stroage ID.

When enabled, the `ssd` property exposes drives as SSDs (rather than
rotational hard disks) by setting QEMU's `rotation_rate` property [1,
2] on `ide-hd`, `scsi-block`, and `scsi-hd` devices. This is required
to enable support for TRIM and SSD-specific optimizations in certain
guest operating systems that are limited to emulated controller types
(IDE, AHCI, and non-VirtIO SCSI).
This change also unifies the diverging IDE and SATA code paths in
QemuServer::print_drivedevice_full(), which suffered from:
* Code duplication: The only differences between IDE and SATA were in
bus-unit specification and maximum device counts.
* Inconsistent implementation: The IDE code used the new `ide-hd`
and `ide-cd` device types, whereas SATA still relied on the deprecated
`ide-drive` [3, 4] (which doesn't support `rotation_rate`).
* Different feature sets: The IDE code exposed a `model` property that
the SATA code didn't, even though QEMU supports it for both.

/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.

*) always replace old cloudinit images
*) apply pending cloudinit changes when generating a new
image
For cloudinit we now always use vdisk_free before
vdisk_alloc in order to always replace old images, this
allows us to hotplug a new drive by setting it to
`none,media=cdrom` first (to eject the disk), then setting
it back to 'storage:cloudinit' to have a new image generated
after applying the currently pending changes.
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.

in case of e.g. a non-existant guest-agent command, it would return
{ error: {someerrorobject} }
but we did only include the 'return' property
in case we do not get any and the error property is set,
return that
i looked at all the paths were we use the QMPClient, and either
we have our own callback for the result,
or we do not rely on the result being empty upon an error, so this
should not break anything

socat tunnel for nbd mirror was introduce here
https://pve.proxmox.com/pipermail/pve-devel/2017-January/024777.html
to workaround when nbd client was hanging on non responding nbd server.
We have added a 30s timeout on socat tunnel, but when we migrate
multiple disks, it can break migration if for example first disk
is already finished and don't send any new datas in the tunnel.
The connect timeout bug has been fixed in qemu 2.9,
so we can remove the socat tunnel now.
With shared=1, (live) migration ignores the disk and assumes it is
present on all target nodes. This works similar to shared=1 on LXC
mountpoints.

Fixes problems in CLIHandler using the code pattern:
while (my $line = <>) {
...
}
For why this causes only _now_ problems lets first look how <>
behaves:
"The null filehandle <> is special: [...] Input from <> comes either
from standard input, or from each file listed on the command line.
Here's how it works: the first time <> is evaluated, the @ARGV array
is checked, and if it is empty, $ARGV[0] is set to "-" , which when
opened gives you standard input. The @ARGV array is then processed
as a list of filenames." - 'perldoc perlop'
Recent changes in the CLIHandler code changed how we modfiied @ARGV
Earlier we assumed that the first argument must be the command and
thus shifted it out of @ARGV, now we can have multiple levels of
(sub)commands. This change also changed how we handle @ARGV, we do
not unshift anything but go through the arguments until we got to
the final command and copy the rest of @ARGV as we know that this
must be the commandos arguments.
For '<>' this means that ARGV was still fully populated and perl
tried to open element as a file, which naturally failed.
Thus the change in pve-common only exposed this 'dangerous' code
pattern.
