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.
New deprecated options and features
Consult the "Deprecated Features" chapter of the QEMU System Emulation User's Guide for further details of the deprecations and their suggested replacements.
