Download VirtualBox 5.1.8

The fourth update for VirtualBox version 5.1 has been released. VirtualBox can be used to install other operating systems in a virtual environment on a computer. In this way it is possible to use different operating systems on the same hardware side by side and at the same time. VirtualBox is available for Windows, macOS, Linux, and Solaris, and is capable of guest operating systems to turn.

In version 5.1 of VirtualBox we find, among other things, new apic implementations that provide various performance improvements, there is improved support for Python 3 and the interface has been switched to Qt5. The following improvements have also been made in this update:

The following items were fixed and/or added:

• GUI: fixed keyboard shortcut handling regressions (Mac OS X hosts only; bugs #15937 and #15938†
• GUI: fixed keyboard handling regression for separate UI (Windows hosts only; bugs #15928†
• NAT: don’t exceed the maximum number of “search” suffixes. Patch from bug #15948†
• NAT: fixed parsing of port-forwarding rules with a name which contains a slash (bug #16002†
• NAT Network: when the host has only loopback nameserver that cannot be mapped to the guests (eg dnsmasq running on 127.0.1.1), make DHCP supply NAT Network DNS proxy as nameserver.
• Bridged Network: prevent flooding syslog with packet allocation error messages (bug #15569†
• Audio: now using Audio Queues on Mac OS X hosts
• Audio: fixed recording with the PulseAudio backend (5.1 regression)
• Audio: various bug fixes
• Snapshots: fixed regression in 5.1.4 for deleting snapshots with several disks (bug #15831†
• Snapshots: crash fix and better error reporting when snapshot deletion failed
• Storage: some fixes for the NVMe emulation with Windows guests
• API: fixed initialization of SAS controllers (bug #15972†
• Build system: make it possible to build VBox on systems which default to Python 3
• Windows hosts: detect certain cases of REGDB_E_CLASSNOTREG errors and print a helpful error message
• Windows hosts: adapted to changes in Windows 10 build 14901 (bug #15944†
• Windows hosts: better support for processor groups on Windows 7 and later which is required on certain hosts with many CPUs

• Linux hosts / guests: fix for kernels with CONFIG_CPUMASK_OFFSTACK set (bug #16020†
