qemu (1.7.0+dfsg-2) unstable; urgency=low qemu-kvm package is back with just a one-line shell wrapper /usr/bin/kvm which runs qemu-system-x86. -- Michael Tokarev Thu, 28 Nov 2013 20:42:53 +0400 qemu (1.3.0+dfsg-2exp) experimental; urgency=low * Since version 1.3 of qemu, all remaining bits of former qemu-kvm were merged into qemu. So since this version, we don't have separate qemu-kvm source package, and qemu-kvm binary package becomes transitional, from qemu-kvm to qemu-system-x86. New executable to run instead of kvm is qemu-system-x86_64. We provide a command-line compatibility wrapper in the usual place, /usr/bin/kvm, which prepends a few command-line flags and calls qemu-system-x86_64. The result should behave the same as old qemu-kvm. The main difference between old qemu-kvm (kvm) binary and qemu-system-x86_64 is that qemu-system-x86_64 (new) does not enable kvm by default, user should do that explicitly by specifying either -enable-kvm option (in which case the command will fail if kvm extensions are not available due to hardware lacking them or other reasons), or using -machine accel=kvm:tcg, which will fall back to emulation mode if kvm can not be initialized. The latter is the way used in the wrapper script. * Old qemu-kvm way to specify bootable device by using ,boot=on device property is not supported by qemu-system-x86_64. That way has been deprecated in Debian version of qemu-kvm for a while too, it worked but produced a warning. The most important reason why it existed was to support booting from SCSI devices (from virtual LSI Logic SCSI controller). This device is now supported natively using bootorder property, like all other devices. * Old qemu-kvm used to emulate virtual Realtek RTL8139 network card by default. New qemu emulates Intel e1000 NIC instead. The latter is more efficient and featureful, but unless you explicitly specified which NIC to emulate, you may need to reconfigure either your guest or the command line you use to run it. * Please note that old qemu-kvm configuration files (in /etc/kvm/) are no longer used. -- Michael Tokarev Tue, 22 Jan 2013 01:12:52 +0400
