QEMU is a versatile piece of software that has lots of different use cases. Here are some common configurations to (manually...) check.

Emulation mode:
 * throw-away, user-mode/non-accelerated emulation
 * KVM guest (incompatible with Xen)
 * Xen HVM guest

User interfaces:
 * virt-manager/libvirt
 * gnome-boxes
 * !ProxMox is Debian-based and would be a good test case, but they ship their own modified qemu version
 * Xen {{{xl}}} CLI

Guest systems:
 * GNU/Linux
 * Windows: trial versions of Windows Server ISOs are easily available; pre-installed VMs are also available through modern.ie, with a [[https://github.com/lentinj/ie-vm|conversion script]]; 2012R2 is known to crash with Xen HVM on first boot (Jessie)

Networking card:
 * basic Ethernet emulation
 * VirtIO networking (accelerated)

Networking attachment:
 * slirp user-mode networking (NAT)
 * bridge
 * ...

Disk types:
 * IDE, SCSI emulation (non-accelerated)
 * VirtIO disk (accelerated, may require [[https://www.linux-kvm.org/page/WindowsGuestDrivers/Download_Drivers|drivers ISO]])
 * iSCSI client/initiator (you can install [[https://packages.debian.org/tgt|tgt]] on a separate box for a test server/target, and {{{qemu-block-extra}}})

Graphic access:
 * SDL (direct window)
 * VNC (e.g. with vncviewer)
 * Spice (e.g. with virt-manager)

== Common issues ==

Make sure you reserve enough memory (-m). For instance, Jessie's default is 128M but running the Stretch installer CD-ROM plain panics with that amount.

== ASAN build ==

[[LTS/Development/Asan]] doesn't support static builds, so in addition to the {{{DEB_*FLAGS_APPEND}}}, drop qemu-user/qemu-user-static from {{{debian/control}}} and {{{debian/control-in}}} before building.
