* pmb.helpers.run: support running processes in background
* enable QXL driver support in the linux kernel configurations so
that we can also use SPICE to connect to the VM.
QXL is a paravirtual graphics driver with 2D support
The SPICE project aims to provide a complete open source solution for remote
access to virtual machines in a seamless way.
Both DRM_QXL and DRM_BOCHS are enabled as modules.
According to [1], on Linux guests, the qxl and bochs_drm kernel modules
must be loaded in order to gain a decent performance
* qemu: add new option --spice to connect to VM using a SPICE client
If specified, 'pmbootstrap qemu' will look for some SPICE client in the
user's PATH and run qemu using the QXL driver.
Currently supported spice clients are 'spicy' and 'remote-viewer' but
adding support for more clients can be easily done.
qemu with qxl support will run on port 8077/tcp, which doesn't belong to
any well-known service and represents 'PM' in decimal.

Thanks to Pablo Castellano and Martijn Braam!
In postmarketOS we are now able to generate system images with the
correct configuration so that they can boot already using qemu
This commit brings the `pmbootstrap qemu` action.
This command is very handy because you don't have to set all the
qemu parameters, pmbootstrap does it for you.
* device-qemu-vexpress: Added kernel command line according to wiki
* qemu: Added workaround for image writing permissions
* qemu: Added support to launch postmarketOS in a QEMU virtual machine
- Support for emulating these architectures in QEMU: arm, aarch64, x86_84
- Generate QEMU command correctly depending no guest architecture (arm/x86)
- Run QEMU in the same architecture as the host by default
- Refactoring in pmb.parse.arch and pmb.qemu.run
- Raise exception if DTB file or system image are not present
- Display more useful information when something fails (e.g. image not found)
- Run qemu version depending on arch (host or argument), not device configured
* device-qemu-amd64: set deviceinfo_kernel_cmdline to "PMOS_NO_OUTPUT_REDIRECT"
* qemu: added --memory argument to specific guest RAM
* device-qemu-amd64: adjusted deviceinfo_kernel_cmdline (console=tty1)
* Added /etc/network/interfaces for qemu-amd64
* qemu: Added KVM support if /dev/kvm if present
* Specify separate machines for architecture
* qemu: Check if QEMU is installed instead of crashing
* Added graphics driver to qemu-aarch64
- Use arm (as used in qemu) instead of armhf (used in Alpine)
- qemu argument is -dtb
- Follow same style to build the command + arguments
* qemu: Added SSH port redirection: ./pmbootstrap.py qemu -p 2222
