Download VirtualBox 5.1.12

The sixth 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 able to 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:

• VMM: fixed VERR_IEM_ASPECT_NOT_IMPLEMENTED Guru Meditations with certain Linux guests if KVM paravirtualization is enabled (5.1 regression; bugs #15613 and #16251)
• VMM: fixed VERR_VMX_UNABLE_TO_START_VM Guru Meditations under rare conditions
• GUI: prevent a crash under certain conditions if the VM is terminated very early
• GUI: fixed certain keyboard capture issues (5.1.10 regression; Mac OS X hosts only; bug #16150)
• GUI: fixed dragging guest windows in seamless mode with the keyboard captured (X11 hosts only; bug #15837)
• GUI: fixed a problem where the new version detected dialog was covered by the appliance import dialog (Mac OS X hosts only; bug #16238)
• Storage: fixed NVMe reset processing when doing rmmod nvme; modprobe nvme in a Linux guest (bug #16080)
• Storage: fixed creating a snapshot when the VM is running and an NVMe controller is present
• Storage: fixed a problem with the LsiLogic SCSI controller where requests could be lost with SMP guests
• E1000: fixed “cable disconnected” issue (Mac OS X guests only; 5.1.10 regression; bug #16260)

• Linux hosts: compile Linux 4.9 compile fix (bug #16286)
• Linux Additions: warn the user about a known bug with older Linux guests (eg Debian 7) requiring manual work to get 3D working (bug #15319)
