Currently, the virtio specification does not include provision for the TRIM (aka DISCARD) command that allows a guest operating system to signal the disk hardware that blocks have become unused so that the underlying device may clear the physical data.
The TRIM/DISCARD command was introduced for SSD disks as an extension to the AHCI specification that is used in SATA systems.
With Virtual Machines we can use this command to tell QEMU's Qcow2 driver to reclaim unused space in the disk image. This ensures the disk image file is kept to the smallest size possible where without the TRIM/DISCARD command it grows to it's maximum configured size and never shrinks again when data is deleted.
Let's swap our default disk driver from `virtio-blk-pci` which does not support TRIM to `virtio-scsi-pci` which does.
QEMU 7.0 introduces a change/regression where it is not possible to use GL accerlation via GTK/SDL displays and also bring up SPICE: https://gitlab.com/qemu-project/qemu/-/issues/1036
This patch prevents Quickemu from bringing up SPICE when GTK or SDK are selected as the display.
Run QEMU with '-vga none' to avoid having two scanouts, one for VGA and another for virtio-vga-gl.
- Workaround for a GTK assertion failure in gtk_widget_get_realized().
- Allows seamless mouse in macOS when using the qxl-vga device.
- Enables sane default resolutions in all support macOS versions.
* Add spice-app as display option
* Rework how we set the default OUTPUT
variable display is never set and display_param_check is already checked when parsing options
* enable overriding the gl param
3d acceleration is not stable on some setups (looking at you, nvidia)

* Extra OVMF search paths needed for Solus
who have moved things around
also spotted a possible typo to investigate in the void additions
* Revert "updated submodule position"
This reverts commit 9648f79b81b5e72465785993bc62469130ac848f.
* minor cleanup
* try realign submodule backwards
- add support to choose preferred usb-controller either ehci (USB2.0) or xhci (USB 3.0)
- add support to choose preferred keyboard either ps2, usb or virtio
- add support to choose preferred keyboard-layout
- add support to choose preferred mouse either ps2, usb, tablet, virtio
- fix some bugs regarding missing variables - releated to MONTITOR_TELNET_* and SERIAL_TELNET_*
- Support implemented on commandline as well as for configuration file
- support commandline parameter --serial, --serial-telnet-host and
--serial-telnet-port
- support serial options: 'socket', 'telnet' and 'none'
- add support to find free ports for monitor-telnet and serial-telnet
- replace nc with socat
- change default port for monitor-telnet to 4440
- some bugfix
- Add commandline parameter --public-dir for custom directory
- Add commandline parameter --monitor for qemu-monitor support
- Add commandline parameter --monitor-telnet-host and --monitor-telnet-port to configure qemu-monitor via telnet
- <VMNAME>.ports enhanced to provide data for monitor-telnet
- Support implemented on commandline as well as for configuration file
- Fixed bug regarding extra_args
- add suport for custom ssh-port and spice-port
- add suport for alternate viewer: 'remote-viewer' and 'none'
- support implemented on commandline as well as for configuration file
* Add support for FreeDOS 1.2 to quickget
* Add support for freedos guests to quickemu
* Add support for FreeDOS 1.3 to quickget
* Force qemu to keep booting from cd after formatting disk
* Adjust VM settings
* Refactor FreeDOS to use create_vm
* Add FreeDOS to README
* Add unzip to README as a dependency
* Add extra_args option in vm conf file
I added this simple piece of code for any extra arguments one wants to use.
You just add extra_args variable to your vm conf file.
ex. add host disk partition
extra_args="-drive file=/dev/sdb2,cache=none,if=virtio"
This is the easiest way to "extend" quickemu functionality.
* add missing variable
* Add support for braille terminal
fixes#307
* Add braille to Readme
* quote tidying
* currently requires sdl display
noted in the docs rather than forcing so if Qemu and/or brtty provide
a solution we will get immediate or easy benefit.
* add needed sdl to braille examples
Haiku is incompatible with the q35 machine type, as it emulates a ICH9
host chipset. Instad, the "pc" machine type needs to be used (emulates
I44FX).

CD-ROM (iso), Disk, Internet and Audio are working now.
Also added forced LiveCD booting (because release named latest-iso, not latest-img).
Did some tweaks with '-machine' and '-cpu'. Now these VMs will run with 'qemu32' processor since KolibriOS throw an MTRR error (I didnt get how to fix it by any other way).
