with this, we are able to create and use mediated devices,
which include Intel GVT-g (aka KVMGT) and Nvidia vGPUs, and probably more
types of devices in the future

else the environment from buildpackage gets overwritten and the '-g'
misses, which results in an debug symbols file without debug

we reverse the direction of the event socket (this does not
prevent live migration) and point it to wher qmeventd listens
Signed-off-by: Dominik Csapak <d.csapak@proxmox.com>
this is intended to be used with qmeventd, to do
the necessary cleanups when qemu crashes or is being
shut down from within the guest
this can also be the point where we could introduce
shutdown/stop/reboot hooks
Signed-off-by: Dominik Csapak <d.csapak@proxmox.com>
this adds a program that can listen to qemu qmp events on a given socket
and if a shutdown event followed by a disconnected socket occurs,
executes qm cleanup with arguments that indicate if the
vm was closed gracefully and whether the guest initiated it
this is useful if we want to cleanup after the qemu process exited,
e.g. tap devices, vgpus, etc.

On arm we start off with a pcie bridge pcie.0. We need a
keyboard in addition to the tablet device, and we need to
connect both to an 'ehci' controller.
To do all this, we also pass the $arch variable through a
whole lot of function calls to ultimately also adapt the
hotplug code to take care of the new keyboard device.

This was never actually used, but we want to use it as
alternative to checking /proc/cpuinfo for 'hvm' on ARM.

SLAAC previously set 'auto' which is not supported by nocloud network
config. On an up-to-date Ubuntu this should work as it uses 'dhcp' for
both dhcp and SLAAC. For others it was invalid anyway.

we changed $vga to a parsed hash instead of a string
and forgot to check the property type in one place
this fixes an issue where a vm with a gpu passed through
with x-vga=on could not start
Signed-off-by: Dominik Csapak <d.csapak@proxmox.com>
we change 'vga' to a property string and add a 'memory' property
with this, the user can better control the memory given to the virtual
gpu, this is especially useful for spice/qxl since high resolutions need
more memory

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.

we will use this for the qmeventd, but we have to limit this
to qemu 2.12, because we cannot add this during a live migration
Signed-off-by: Dominik Csapak <d.csapak@proxmox.com>
Instead of our own. The code is almost the same, but the
upstream implementation uses qemu's transactional system and
performs a drain() on the block device first. This seems to
help avoid some issues we run into with qcow2 files when
creating snapshots.
