qemu (1.3.0+dfsg-4exp) experimental; urgency=low
Starting from 1.3.0 release, qemu-system package, which provided
QEMU system emulation targets for many architectures, has been
split into several packages, each providing a related,
per-base-architecture, set of emulators, and qemu-system-misc
package which contains some "other" architectures. There are
also qemu-system-common package, which provides common files for
all other qemu-system-*, packages. Former qemu-system package
now become a meta-package which installs emulators for all
available targets as before.

qemu (0.12.3+dfsg-3) unstable; urgency=low
Starting with QEMU 0.12.0, KQEMU support has been removed from
upstream, as it has not seen active development for a few years now,
while causing regressions or limitations for non-KQEMU users.

qemu (0.10.3-2) unstable; urgency=low
Starting with QEMU 0.10.0, it is possible to control how the host
cache is used to access block data, using the cache= suboption of the
-drive option. The following suboptions are available:
* none: The host page cache is entirely avoided.
* writeback (default in QEMU 0.9.x): Writeback caching reports data
writes as completed as soon as the data is present in the host page
cache. This is safe as long as you trust your host. If your host
crashes or loses power, then the guest may experience data
* writethrough (default in QEMU 0.10.x): The host page cache is used
to read and write data but write notification is sent to the guest
only when the data has been reported as written by the storage
Note that depending on your configuration (filesystem, encryption,
kernel version, etc.), disk accesses can be very slow with the default
cache policy (writethrough). You can use the writeback cache policy
instead, but the data integrity is not assured anymore.
See qemu(1) for more details.
