The problem with 3D support is essentially that you need to use the proprietary Windows drivers with direct access to the GPU (because GPUs themselves aren't virtualizable). There is a way round it using VFIO and video passthrough (I use it for gaming) but it requires a lot of setup and depends on your specific hardware, BIOS and chipset. poc ___ users mailing list -- users@lists.fedoraproject.org To unsubscribe send an email to users-le...@lists.fedoraproject.org Fedora Code of Conduct: https://getfedora.org/code-of-conduct.html List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@lists.fedoraproject.org

I have tried KVM periodically, but the performance is always horrible with Windows VMs, and since having a place to run all that "windows-only" software is my primary reason for using VMs, I have always been forced back to VirtualBox. --Greg ___ users mailing list -- users@lists.fedoraproject.org To unsubscribe send an email to users-le...@lists.fedoraproject.org Fedora Code of Conduct: https://getfedora.org/code-of-conduct.html List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@lists.fedoraproject.org

Re: Thunar confused by kernel 5.0.5
Sam Varshavchik: Is anyone running XFCE seeing Thunar being very confused when booting kernel 5.0.5? Mine no longer automounts my removable usb storage mp3 player. As a consolation prize, of sorts, Thunar informs me that /boot, /home, /sys, and the like, are removable volumes, and shows a folder icon for each one of them on the desktop. With an option to unmount them, of course. Plugging and unplugging the USB device is detected, in some way, with the typical stuff showing up in /var/log/messages, but thunar doesn't see it. Everything's fine in 5.0.4. I use Xfce and have the same kernel (5.0.5), no problems here. -- David Dusanic ___ users mailing list -- users@lists.fedoraproject.org To unsubscribe send an email to users-le...@lists.fedoraproject.org Fedora Code of Conduct: https://getfedora.org/code-of-conduct.html List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@lists.fedoraproject.org
Fedora Virtualization (quemu/kvm) vs Virtualbox
On a i7+16Gb+SSD notebook of a my friend I have install Fedora 29 workstation (all work fine! ... thank to all!) and into qemu/kvm/libvirtd via virt-manager I have install a win10pro with all virtio driver (disk, network, ecc..). After few days my friend say me that the win10 is slow and less efficient than same installation on another PC with VirtualBox. He told me "virtualbox is better and faster" I have heard this statement in other cases in the past and the only solution (sig!) was to replace qemu with virtualbox. There is some other solution to optimize qemu/kvm on Fedora to increase the performance for win10 VM? Someone has some performance comparison between the two virtualization system?
