Install vde2 and uml-utilities (for tunctl). With VDE it is possible to create a virtual network of QEMU machines running on one or more real computers. Virtual Distributed Ethernet (VDE) provides is a virtual switch that can connect multiple virtual machines together, both local and remote. eth0 => eth1), so add extra interface stanzas in the guest interfaces file to configure these. If you run more guests from the same image file, udev will rename the interface to avoid duplication (e.g. To run additional guests, duplicate the lines in the bridge stanza for tap1, tap2 as needed and change the ifname argument in the command line. DHCP will work so this is simplest way to go. The guest virtual network adapters will be configured by the /etc/network/interfaces file in the guest file system. Script=no,downscript=no disable the scripts /etc/qemu-ifup and /etc/qemu-ifdown as they are not needed. Ifname=tap0 - the tap name here corresponds with the name in the bridge stanza above. Launch QEMU: $ qemu-system-x86_64 -hda imagefile.img -net nic -net tap,ifname=tap0,script=no,downscript=no See bridge-utils-interfaces(5) - note that the man page warns against adding wireless adapters to the bridge (see also BridgeNetworkConnections). The three other bridge directives will speed up the activating of the bridge.

On the 'bridge_ports' line, 'all' adds all physical interfaces to the bridge virtual interfaces have to be listed explicitly. A tap device is created owned by and is brought up please note that is the username on the host system. Post-down ip tuntap del dev tap0 mode tapД®xplanation: this stanza auto loads a bridge and configures it using DHCP. Pre-up ip tuntap add dev tap0 mode tap user Remove the 'auto' line and change the 'method' of your physical, wired network adapters from 'auto' to 'manual': #auto eth0 Please note that all these changes must be done on the host system. To create a bridge between host and guests, do the following (tested on DebianSqueeze). The host and guest will not see each other. That will push out deleted file scraps, recompression should work then.Д«y default, QEMU invokes the -nic and -user options to add a single network adapter to the guest and provide NATed external Internet access. If the guest system's image is still larger than reasonable, then open up the Guest system and run ' ddВ if=/dev/zeroВ of=/tmp/junkВ В syncВ В rmВ /tmp/junk'. This conversion will save the same space and still be runnable: $ qemu-img convert -c debian.img -O qcow debian_recompressed.img After unpacking with tar xf, the sparse file is restored and can be booted immediately.Д«etter still, convert from a sparse file into the qemu's own 'Copy On Write' image. This creates a tar file of about 320M (supposed that the image contains a 1.9GB ext3 root filesystem and a 250MB swap partition). After installing a Debian base system, it fits on a CD-ROM even without compression: $ tar c -sparse -f backup.tar debian.img The disk image 'debian.img' is a sparse file. Install the system as usual to set up a sid system choose 'unstable' when being asked by the installer.ДЄfter the installation is done, the system can be booted with: $ qemu-system-x86_64 -hda debian.img -m 512.When the usual debian boot screen appears, boot into 'expert' mode.If you have KVM, you can use it by including the option -enable-kvm.the businesscard image at Д«oot the image with: $ qemu-system-x86_64 -hda debian.img -cdrom debian-testing-amd64-netinst.iso -boot d -m 512 Or with the qcow2 disk image format if you want to use QEMU's own 'Copy On Write' image format: $ qemu-img create -f qcow2 debian.qcow 2GДownload a current boot image, e.g. If you're installing a desktop environment, you'll need more than 2G. A sid system can be set up with the following steps:Д¬reate the hard disk image with: $ qemu-img create debian.img 2G

QEMU is especially handy to set up an emulated testing/unstable system when working on the Debian installer itself or on the boot system, or when trying some experimental features without impact on the productive system.
