changelog v2:
- remove hash
- remove check if cdrom
if we try to delete a snapshot, and that is disk from the snapshot
is not attached anymore (unused), we can't delete the snapshot
with qemu snapshot delete command (for storage which use it (qcow2,rbd,...))
example:
...
unused0: rbd:vm-107-disk-3
[snap1]
...
scsi2: rbd:vm-107-disk-3,size=1G
-> die
qmp command 'delete-drive-snapshot' failed - Device 'drive-scsi2' not found
If drive is not attached, we need to use the storage snapshot delete command
tells an user what would get touched, so he has a chance to fix
unwanted things before changes are actually made.

Else an user has no idea what, or if something happened.
Gets printed to tty when using qm rescan or to tasklog for the case
where we do a rescan after restoring a backup.

Unused disk(s) appeared after a rescan of storages. Especially shown
with ceph pools, where two storage entries are made, <storage>_ct and
<storage>_vm. The rescan method did include images from both storages.
This patch filters any storage not containing the content type 'images'.

when a vm is suspended (e.g. autosuspend on windows)
we detect that it is not running, display the resume button,
but 'cont' does not wakeup the system from suspend
with this we can wake up suspended vms

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.

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

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
c971c4f221 (29.05.2012)
Already tried to remove this with commit
7b7c6d1b5d (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 dab36e1ee9 (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.

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.

move: don't error out with "you can't move a cdrom"

They get completely replaced anyway at the next start, so

*) 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.
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.
