[-- Attachment #1 --] What I find strange is that this configuration works on Windows 11 to virtualize FreeBSD using -device vmware-svga : I:\OS\vms\qemu\qemu-system-x86_64w.exe -accel whpx -machine q35 -cpu kvm64,hv_relaxed,hv_time,hv_synic -m 8G -device vmware-svga,id=video0,vgamem_mb=16,bus=pcie.0,addr=0x1 -audiodev dsound,id=snd0 -device ich9-intel-hda -device hda-duplex,audiodev=snd0 -hda "I:\Backup\FreeBSD\FreeBSD-140-zfs.img" -device hda-duplex,audiodev=snd0 -drive file=\\.\PhysicalDrive4 -drive file=\\.\PhysicalDrive5 -drive file=\\.\PhysicalDrive6 -drive file=\\.\PhysicalDrive8 -drive file=\\.\PhysicalDrive12 -rtc base=localtime -device usb-ehci,id=usb,bus=pcie.0,addr=0x3 -device usb-tablet -device usb-kbd -smbios type=2 -nodefaults -netdev tap,id=mynet0,ifname="OpenVPN-TAP-Windows",script=no,downscript=no -device e1000,netdev=mynet0,mac=52:55:00:d1:55:01 -device ich9-ahci,id=sata -bios "I:\OS\vms\qemu\OVMF_combined.fd" One can think that it will work even on Linux for the same setup (qemu + hyper-V on Windows 11),but it does not. I'm experiencing a lot of problems when I add -accel whpx on a Debian VM. These problems go away if I remove it. Adding " -device vmware-svga,id=video0,vgamem_mb=16,bus=pcie.0,addr=0x1" to the qemu / Debian parameters will cause it won't boot. So,this : I:\OS\vms>I:\OS\vms\qemu\qemu-system-x86_64.exe -machine q35 -cpu kvm64,hv_relaxed,hv_time,hv_synic -m 8G -device vmware-svga,id=video0,vgamem_mb=16,bus=pcie.0,addr=0x1 -audiodev dsound,id=snd0 -device ich9-intel-hda -device hda-duplex,audiodev=snd0 -hda "I:\Backup\Linux\Debian.img" -drive file=\\.\PhysicalDrive5 -drive file=\\.\PhysicalDrive6 -drive file=\\.\PhysicalDrive8 -rtc base=localtime -device usb-ehci,id=usb,bus=pcie.0,addr=0x3 -device usb-tablet -device usb-kbd -smbios type=2 -nodefaults -netdev user,id=net0 -device e1000,netdev=net0,id=net0,mac=52:54:00:11:22:33 -device ich9-ahci,id=sata -bios "I:\OS\vms\qemu\OVMF_combined.fd" will cause the Debian VM to freeze before reaching the login prompt. I don't know if Linux has the proper vmware-svga driver,I didn't find it. Regarding virtualizing Windows 7 on Windows 11 using the same setup,I can't add -accel whpx and most importantly,what I care more, the -device vmware-svga does not work. So,in this kind of setup, *FreeBSD is the winner because it supports everything (hyper-V and the vmware-svga 3D accelerated device.* On Sat, Apr 27, 2024 at 9:41 PM Yusuf Khan <yusisamerican@gmail.com> wrote: > So your issue is that the performance is worse than Linux? > > There is no 3d graphics driver for virtio in mainline drm-kmod but > https://github.com/freebsd/drm-kmod/pull/119 has > experimental support, although that PR exists it seems to be > non-functional with a crash. > -- Mario.
