qemu cardoe@gentoo.org Doug Goldstein Adds support for braille displays using brltty Enables support for Linux's Async IO Enable alsa output for sound emulation Support ISOs / -cdrom directives vis HTTP or HTTPS. Enables firmware device tree support Enables GlusterFS cluster fileystem via sys-cluster/glusterfs Enable direct iSCSI support via net-libs/libiscsi instead of indirectly via the Linux block layer that sys-block/open-iscsi does. Enable audio mixer emulation. On Fedora, known to cause performance problems when using SDL output and ALSA. For OSS, locks the sound device from other applications. Enable the ncurses-based console Enable NFS support Enable NUMA support Pin the versions of BIOS firmware to the version included in the upstream release. This is needed to sanely support migration/suspend/resume/snapshotting/etc... of instances. When the blobs are different, random corruption/bugs/crashes/etc... may be observed. Enable pulseaudio output for sound emulation Enable rados block device backend support, see http://ceph.newdream.net/wiki/QEMU-RBD Enable the SDL-based console Utilize sys-libs/libseccomp to enable kernel filtering of system calls to prevent malicious guests from doing damage. Enable Spice protocol support via app-emulation/spice Enable SSH based block device support via net-libs/libssh2 Builds the Software MMU (system) targets as static binaries Build the User targets as static binaries Enables both 'static-softmmu' and 'static-user' Enable support for snappy compression Enable SystemTAP/DTrace tracing Enable the TCG Interpreter which can speed up or slowdown workloads depending on the host and guest CPUs being emulated. In the future it will be a runtime option but for now its compile time. Enable TLS support for the VNC console server. For 1.4 and newer this also enables WebSocket support. For 2.0 and newer this also enables disk quorum support. Enable jpeg image support for the VNC console server Enable png image support for the VNC console server Enable USB passthrough via dev-libs/libusb Use sys-apps/usbredir to redirect USB devices to another machine over TCP Enable UUID support in the vdi block driver Enable VDE-based networking Enable accelerated networking using vhost-net, see http://www.linux-kvm.org/page/VhostNet Enable VirtFS via virtio-9p-pci / fsdev. See http://wiki.qemu.org/Documentation/9psetup Add support for getting and setting POSIX extended attributes, through sys-apps/attr. Requisite for the virtfs backend. Enables support for Xen backends Support xfsctl() notification and syncing for XFS backed virtual disks.
