Pass-through method only works for TCP and UDP connections. To get more performance use the same color depth for your host as you use in the guest.

-vga qxl - More powerful graphics card for use with SPICE.

#QEMU MONITOR INSTALL#

Install x11-drivers/xf86-video-vmware in Linux guests, VMware Tools in Windows XP and newer guests. -vga vmware - VMware SVGA-II, more powerful graphics card.Linux, Windows XP and newer guest have a built-in driver. -boot d - Boot the first virtual CD-ROM drive.-boot c - Boot the first virtual hard drive.With this syntax you can set multiple drives. -drive file=IMAGE.iso,media=cdrom - Set a virtual CDROM drive and use the specified image file for it.-drive - Advanced configuration of a virtual CDROM drive:.-cdrom /dev/cdrom - Set a virtual CDROM drive and use the host drive for it.-cdrom IMAGE.iso - Set a virtual CDROM drive and use the specified image file for it.The AHCI emulation supports NCQ, so multiple read or write requests can be outstanding at the same time. -drive id=disk,file=IMAGE.img,if=none -device ahci,id=ahci -device ide-hd,drive=disk,bus=ahci.0 - Set emulation layer for an ICH-9 AHCI controller and use the specified image file for it.-drive file=/dev/sdX#,cache=none,if=virtio - Set a virtual VirtIO-BLK hard drive and use the specified partition for it.-drive file=IMAGE.img,if=virtio - Set a virtual VirtIO-BLK hard drive and use the specified image file for it.You need at least one virtio-scsi-controller and for each block device a -drive and -device scsi-hd pair. -device virtio-scsi-pci,id=scsi0 -drive file=/dev/your/block,if=none,format=raw,discard=unmap,aio=native,cache=none,id=someid -device scsi-hd,drive=someid,bus=scsi0.0 Very fast Virtio SCSI emulation for block discards ( TRIM), native command queuing ( NCQ).-drive - Advanced configuration of a virtual hard drive:.-hda IMAGE.img - Set a virtual hard drive and use the specified image file for it.For instance: -m 256M ( M stands for Megabyte, G for Gigabyte). -m MEMORY - Specify the amount of memory (default: 128 MB).

Use -smp $(nproc) to use all currently available cores. The number can be higher than the available cores on the host system.

-smp - Specify the number of cores the guest is permitted to use.

-cpu host - (Recommended) Emulate the host processor.

To see a list of supported architectures, run: qemu-system-x86_64 -cpuВ ?

-cpu - Specify a processor architecture to emulate.

-object rng-random,id=rng0,filename=/dev/urandom -device virtio-rng-pci,rng=rng0 - Pass-through for host random number generator.

) and hardware virtualization acceleration

-machine type=q35,accel=kvm - Modern chipset (PCIe, AHCI.

Substitute X for the number of the display (0 will then listen on 5900, 1 on 5901, etc).ДЇor example to have QEMU send the display to a GTK window add the following option to the list:

-display vnc=127.0.0.1: - Start a VNC server on display X (accepts an argument (X) for the display number).

This is probably the option most users are looking for.

-display gtk - Display video output in a GTK window.

This option is different than the -nographic option.

-display none - Do not display video output.

-display curses - Displays video output via curses.

-display sdl - Display video output via SDL (usually in a separate graphics window).

There are a few available options to specify the kind of display to use in QEMU.
