355 <title>Using Qemu</title>
356
357 <para>
358 Since using qemu means using a virtual computer, the steps to set up
359 the virtual machine are in close analogy with those to set up a real
360 computer. You'll need to decide about CPU, memory, disk, USB devices,
361 network card(s), screen size, etc. Once the <quote>hardware</quote> is
362 decided, you'll have for example to choose how to connect the machine
363 to internet, and/or to install an OS. In the following, we show basic
364 ways of performing those steps. But qemu is much more than this, and it
365 is strongly advised to read the qemu documentation in
366 <filename>/usr/share/doc/qemu-&qemu-version;/qemu-doc.html</filename>.
367 </para>
368
369 <note>
370 <para>
371 It is standard practice to name the computer running qemu
372 <quote>host</quote> and the emulated machine running under qemu the
373 <quote>guest</quote>. We'll use those notations in the following.
374 </para>
375 </note>
376
377 <note>
378 <para>
379 The following instructions assume the optional symbolic link,
380 <filename>qemu</filename>, has been created. Additionally,
381 <command>qemu</command> should be run in a graphical environment.
382 But it is possible to use qemu <quote>headless</quote> or through
383 SSH. See the documentation for the various possibilities.
384 </para>
385 </note>
386
387 <bridgehead renderas="sect3">Disk</bridgehead>
388 <para>
389 A virtual disk may be set up in the following way:
390 </para>
391
392<screen><userinput>VDISK_SIZE=<replaceable>50G</replaceable>
393VDISK_FILENAME=<replaceable>vdisk.img</replaceable>
394qemu-img create -f qcow2 $VDISK_FILENAME $VDISK_SIZE</userinput></screen>
395
396 <para>
397 The virtual disk size and filename should be adjusted as desired. The
398 actual size of the file will be less than specified, but will expand as
399 needed, so it is safe to put a high value.
400 </para>
401
402 <bridgehead renderas="sect3">Operating System</bridgehead>
403 <para>
404 To install an operating system, download an iso image from your preferred
405 Linux distribution. For the purposes of this example, we'll use
406 <filename>Fedora-16-x86_64-Live-LXDE.iso</filename> in the current
407 directory. Run the following:
408 </para>
409
410<screen><userinput>qemu -enable-kvm \
411 -drive file=$VDISK_FILENAME \
412 -cdrom Fedora-16-x86_64-Live-LXDE.iso \
413 -boot d \
414 -m <replaceable>1G</replaceable></userinput></screen>
415
416 <para>
417 Follow the normal installation procedures for the chosen distribution.
418 The <parameter>-boot</parameter> option specifies the boot order of
419 drives as a string of drive letters. Valid drive letters are: a, b
420 (floppy 1 and 2), c (first hard disk), d (first CD-ROM). The
421 <parameter>-m</parameter> option is the amount of memory to use for the
422 virtual machine. The choice depends on the load of the host. Modern
423 distributions should be comfortable with 1GB.
424 The <parameter>-enable-kvm</parameter> option allows hardware
425 acceleration. Without this switch, the emulation is much slower.
426 </para>
427
428 <bridgehead renderas="sect3">Defining the virtual hardware</bridgehead>
429 <para>
430 The virtual machine hardware is defined by the qemu command line.
431 An example command is given below:
432 </para>
433
434<screen><userinput>qemu -enable-kvm \
435 -smp 4 \

528 this option if you want to boot the guest OS with UEFI.
529 </para>
530
531 <para>
532 <option>-drive file=&lt;filename&gt;,if=virtio</option>: Provide
533 Virtio interface to the guest kernel for accessing the disk image,
534 instead of simulating a real disk hardware. This can improve disk I/O
535 performance, but it requires a Virtio driver in guest kernel. Use
536 it instead of a plain <option>-drive</option> if the guest kernel

538 guest, use
539 <command>make defconfig &amp;&amp; make kvm_guest.config</command> to
540 create an initial kernel configuration with the Virtio drives enabled,
541 then make your customization. And, if the guest kernel is Linux, the
542 virtual disks using Virtio interface will be named
543 <filename>vdx</filename> in the devtmpfs, instead of
544 <filename>sdx</filename>.

548 <option>-net nic,netdev=net0,model=virtio-net-pci</option>: Provide
549 Virtio interface to the guest kernel for accessing the network
550 interface, instead of simulating a real network interface card. This
551 can improve network I/O performance, but it requires a Virtio driver
552 in guest kernel. Use it instead of a plain <option>-net</option> if
553 the guest kernel supports Virtio.

564 The above solution for networking allows the guest to access the local
565 network through the host (and possibly to access internet through the
566 local routers), but the converse is not true. Not even the host can
567 access the guest, unless port forwarding is enabled. And in the case
568 several guests are running, they cannot communicate with each other.
569 Other network devices can be used for this purpose. For example, there
570 is the <quote>socket</quote> device, which allows several guests to
571 share a common virtual network. In the following, we describe in more
572 details how to set up the <quote>bridge</quote> device, which allows
573 the guests to appear as if connected to the local network. All the
574 commands below should be run as the <systemitem
575 class="username">root</systemitem> user.
