ChangeLog/9.0

System emulation

Removed features and incompatible changes

Consult the 'Removed features' page for details of suggested replacement functionality.

• Running QEMU with KVM requires Linux 4.4 or newer. A future version of QEMU will increase the minimum requirement for Arm hosts to Linux 4.19 (also when running KVM); if this is too restrictive for your use case, please contact us at qemu-devel@nongnu.org.
