parse_cmdline is required for upcoming changes related to custom CPU
types and live migration, and this way we can re-use existing code.
Provides the necessary infrastructure to parse QEMU /proc/.../cmdline.
Changing the single user (check_running) is trivial too.

Also remove unused $confdir variable in QemuConfig, but leave it and
$lock_dir there, since those paths should only be used with
cfs_config_path anyway.
nodename() is still called in multiple places, but since it's cached by
INotify it doesn't really matter.

Out code behaves like either l26 or other when the ostype is
undefined, both are not common as our webinterface _always_ sets the
ostype.
If one configured QXL with a VM as output device but does not has an
ostype set, and that works without "max_outputs=4" it really should
work with none too.

with pve-qemu-4.0.1-3 or higher it was not possible in a spice remote
session to enable more displays on the fly in linux guests.
Adding the `max_outputs` parameter to the qxl device manually restores
the functionality.

While we may not want to copy the cloudinit disk/drive, we still need
to create+allocate the volume, else the next start complains about a
missing CI drive..

This adds an extra field to agent_fmt that specifes the type of guest
agent connection to use. Currently there is no choice, and defaults to
virtio-serial. Since qemu-ga also runs over isa-serial, this allows OSes
such as NetBSD and OpenBSD, which do not have support for virtio-serial,
to run a qemu-ga.
This is an optional field, which leaves the default as virtio-serial. As
it doesn't change the default, it will require no change to older
configuration files.

Show storages configured for the target node and not for the current one
because they can be different.
Duplicated the `complete_storage` sub and extended it to extract the
targetnode from the parameters to pass it into the storage_check_enabled
function.

since PVE::Cluster::get_local_migration_ip does not exist anymore. this

the reboot request is only cleaned in the vm_start path, so if reboot
fails for some reason, the request still exists. this causes an
unintentional reboot when a shutdown/stop/hibernate is called.
to mitigate, we can just clear the reboot request in case of an error.

This brings qemu more in line with containers, and it's nicer to
allow passing the replacement config if we want to keep it, instead
of setting a "memory: 128" config.
Use that to lock it on removal before final deletion, and on legacy
tar archive restore, in between old VM destruction and new
restoration.

it has some potential semantic change too, i.e., the Storage
vdisk_list call is not wrapped by eval anymore, put as
we did some (unguarded) storage things before that call I'd say that
that does not matters much..
We try to clean all unused disks too, even if one deletion fails

When calling qmrestore a config file is created and locked with a lock
property. The following destroy_vm has been impossible as skiplock has not
been set.
Signed-off-by: Dominic Jäger <d.jaeger@proxmox.com>
This function has been used in one place only into which we inlined its
functionality. Removing it avoids confusion between vm_destroy and vm_destroy.
The whole $importfn is executed in a lock_config_full.
As a consequence, for the inlined code:
1. lock_config is redundant
2. it is not possible that the VM has been started (check_running) in the
meanwhile
Additionally, it is not possible that the "lock" property has been written into
the VM's config file (check_lock) in the meanwhile
Add warning after eval so that it does not go unnoticed if it ever comes into
action.

with qemu 4.0.1, there is now a machine type pc-q35-4.0.1 which does not fit
into our regex
this broke live migration of q35, as we give the machine type (incl version
info) to 'qm start' on the target node, which checks it against the
JSONSchema
to fix this, extend the regex to allow any number of version levels,
for q35, i440fx and virt (to be more future proof)

As mentioned on the mailing list [0] disks owned by the VM and unused

As mentioned in #2408, live-migrating a VM between storages that use
different scsi backends (scsi-hd, scsi-generic, scsi-block) breaks.
To fix, from QEMU 4.1 machine types onward (to not break current
behaviour any more), only use scsi-hd, as in recent versions, there is
almost no difference between the two anyway.
scsi-block (which potentially also breaks) requires a flag to be
manually set on the disk, so we can assume the user knows what they're
doing.

Each pending options has a hash value which has the 'force'
information encoded as entry. But, this can be { force => 1 } or
{ force => 0 }, so we actually need to check the value and not just
set force to the hash directly, as else we have force always truthy..
fixes a bug where 'detach' caused disks to be destroyed immediately,
because $force parameter was always true since hash is true.

brings us more in line with what we do in pve-container, also it's

So, while we could just make this a special case before the
config_to_command call and set the $conf->{vmstate} to the statefile
for the case were it's a valid volumeid, the special case handling
get's much easier when we do this outside of that method.
So it's basically a trade-off, and after looking far to long at all
nice revisions Alwin made for me and Fabians request, and even trying
out different approaches, it was never perfect.
But having slight code duplication over the movement mess I proposed
(as I did not had the full picture then, sorry Alwin) felt like the
slightly nicer trade off, as all worked I just use this one now, it
has very clear semantics, easy to understand and that now three lines
are duplicated is IMO irrelevant.

the volume id list is only used to activate before real start and
deactivate later, so use it for the vmstate file too.
This not only makes config_to_command have less side effects, it also
ensures that the vmstate is deactivated again
