VirtualBox related: VirtualBox Guest Additions Installation In Ubuntu, Linux Mint, Debian, Fedora And openSUSE Yet another improvement is the addition of support for the latest stable Linux 5.4 (available in the current Ubuntu 20.04 development and Debian experimental for example).
This is Windows guest/host only for now, it's disabled by default and it can be enabled by using VBoxManage ( -clipboard-file-transfers enabled|disabled - specifies if clipboard file transfers are allowed between host and guest OSes or not). VirtualBox 6.1 also includes a new experimental feature that allows transferring files between via the shared clipboard. Want to know the difference between these graphics controllers? See this page.Īs a side note, the old VBoxVGA can still be selected in the VirtualBox GUI on my Linux desktop despite what the changelog says, but the machine fails to start, so make sure you don't choose this graphics controller when using VirtualBox 6.1+. VBoxSVGA and VMSVGA now support YUV2 and related texture formats with hosts using OpenGL (macOS and Linux), which accelerates video playback when 3D is enabled by delegating the color space conversion to the host GPU. The new style 3D support (VBoxSVGA and VMSVGA) has also been further improved, with the older 3D support (VBoxVGA) being removed in this release. This release adds support for Intel CPUs starting with 5th generation Core i (Broadwell). Nested virtualization was introduced with VirtualBox 6.0 and it initially only supported host systems that run AMD CPUs.
This allows you to install a hypervisor like VirtualBox or KVM, on a VirtualBox guest, so you can then create and run virtual machines in the guest virtual machine. Also, the Oracle Cloud Infrastructure now has enhanced support for exporting a virtual machine to Oracle Cloud Infrastructure, allowing the creation of multiple VMs without re-uploading.Īnother significant improvement in this release is enhanced support for nested hardware virtualization. The new VirtualBox 6.1 brings the ability to import a virtual machine from Oracle Cloud Infrastructure, by launching the Import Appliance feature.
VirtualBox is a x86 and AMD64/Intel64 virtualization software that runs on Windows, Linux, macOS and Solaris, and supports many guest operating systems, including Windows Linux, Solaris, OpenSolaris, OS/2 and OpenBSD. I have tried having 4 GiB and 8 GiB allocated for the guest.A new major VirtualBox version has been released, bringing improvements for the new VBoxSVGA and VMSVGA graphics controllers, experimental support for file transfers via shared clipboard, support for Linux 5.4, and more. I have tried having 1, 2, and 4 cores enabled for the guest. This problem is not related to misconfiguration of the number of cores or memory for the guest. I have never experienced this slow performance before in VirtualBox, something is clearly wrong, but what is it? And how can I fix it? VirtualBox claims 2D acceleration only works for a Windows guest, so it is disabled. It seems like "Enable Nested VT-x/AMD-V" is not possible to select in the options for the guest. Interestingly, glxgears runs seemingly fine, but again, moving the window itself takes seconds and is extremely sluggish. I can verify that the usual vbox modules are running:Įverything works fine in Debian, except that the system is extremely slow.Įven the mouse cursor lags when moved around, on a clean system with nothing running. I have installed the guest additions, no errors.
I have Mojave 10.14.3, running VirtualBox 6.0.4 and with Debian 9 (with XFCE) as the guest OS.
