* 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.
