Additionally, for users relying on NAT, the scenario where virtual machines with excessively long names refuse to start has also been effectively addressed.<\/p>\n\n\n\n<p>Linux hosts received targeted attention, specifically addressing a severe issue causing potential kernel panics when bridged networking was used alongside network interfaces managed by the ixgbe driver on newer kernels.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/linuxiac.com\/wp-content\/uploads\/2025\/07\/virtualbox7112-app.jpg\"><img decoding=\"async\" width=\"1024\" height=\"635\" src=\"https:\/\/linuxiac.com\/wp-content\/uploads\/2025\/07\/virtualbox7112-app-1024x635.jpg\" alt=\"VirtualBox 7.1.12\" class=\"wp-image-177545\" srcset=\"https:\/\/linuxiac.com\/wp-content\/uploads\/2025\/07\/virtualbox7112-app-1024x635.jpg 1024w, https:\/\/linuxiac.com\/wp-content\/uploads\/2025\/07\/virtualbox7112-app-380x236.jpg 380w, https:\/\/linuxiac.com\/wp-content\/uploads\/2025\/07\/virtualbox7112-app-768x476.jpg 768w, https:\/\/linuxiac.com\/wp-content\/uploads\/2025\/07\/virtualbox7112-app.jpg 1489w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/a><figcaption class=\"wp-element-caption\">VirtualBox 7.1.12<\/figcaption><\/figure>\n\n\n\n<p>On the Windows side, several critical improvements have been implemented. Users who previously experienced the dreaded Blue Screen of Death when closing the VirtualBox graphical interface after uninstalling the host package can now operate without worry.<\/p>\n\n\n\n<p>Additionally, Oracle has made general improvements to driver installation on Windows hosts, enhancing the user experience with smoother and more predictable setups.<\/p>\n\n\n\n<p>Furthermore, Windows host users who rely on Hyper-V can now expose AVX and AVX2 instructions to their guest systems. Additionally, the recording feature, which previously prevented some Windows guest machines from starting when recording was enabled in display settings, has also been fixed.<\/p>\n\n\n\n<p>Regarding Linux compatibility, Oracle has added essential fixes that support the upcoming Linux kernel 6.16, alongside rectifying issues affecting older Linux kernel series.<\/p>\n\n\n\n<p>Lastly, users of the Linux Guest Additions now have accurate reporting from the <code>rcvboxadd status-kernel<\/code> command on kernel versions 3.10 and older, as well as resolved initialization problems with VBoxClient on kernel 2.6 series and below.<\/p>\n\n\n\n<p>Refer to the&nbsp;<a href=\"https:\/\/www.virtualbox.org\/wiki\/Changelog-7.1#v12\" target=\"_blank\" rel=\"noreferrer noopener\">changelog<\/a> for more information about all the changes in the new version.
