April 28, 201610 yr I have been using and writing a lot of Docker images and thought that I would take a look at VMs. However, none will start: LC_ALL=C PATH=/bin:/sbin:/usr/bin:/usr/sbin HOME=/ QEMU_AUDIO_DRV=none /usr/local/sbin/qemu -name 'Windows 7' -S -machine pc-i440fx-2.5,accel=kvm,usb=off,mem-merge=off -cpu host,hv_time,hv_relaxed,hv_vapic,hv_spinlocks=0x1fff,hv_vendor_id=none -m 2048 -realtime mlock=off -smp 2,sockets=1,cores=1,threads=2 -uuid e8e3ee70-eaa9-e1cd-68e6-14c24d766113 -no-user-config -nodefaults -chardev 'socket,id=charmonitor,path=/var/lib/libvirt/qemu/domain-Windows 7/monitor.sock,server,nowait' -mon chardev=charmonitor,id=monitor,mode=control -rtc base=localtime -no-hpet -no-shutdown -boot strict=on -device ich9-usb-ehci1,id=usb,bus=pci.0,addr=0x7.0x7 -device ich9-usb-uhci1,masterbus=usb.0,firstport=0,bus=pci.0,multifunction=on,addr=0x7 -device ich9-usb-uhci2,masterbus=usb.0,firstport=2,bus=pci.0,addr=0x7.0x1 -device ich9-usb-uhci3,masterbus=usb.0,firstport=4,bus=pci.0,addr=0x7.0x2 -device virtio-serial-pci,id=virtio-serial0,bus=pci.0,addr=0x4 -drive 'file=/mnt/cache/.keep/vm/Windows 7/v-device qxl-vga,id=video0,ram_size=67108864,vram_size=67108864,vgamem_mb=16,bus=pci.0,addr=0x2 -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x6 -msg timestamp=on Domain id=2 is tainted: high-privileges Domain id=2 is tainted: host-cpu char device redirected to /dev/pts/0 (label charserial0) I have tried selecting other CPU cores etc. This seems to be the problem: Domain id=2 is tainted: high-privileges Domain id=2 is tainted: host-cpu argggg: I guess I need IOMMU capability?.

April 28, 201610 yr Author There is no option to enable iommu in the bios that I can see. HVM is enabled though. Is IOMMU a requirement for VMs?
April 28, 201610 yr There is no option to enable iommu in the bios that I can see. HVM is enabled though. Is IOMMU a requirement for VMs? Look for VT-d in the BIOS, i suspect it will be disabled. Just enable it (VT-d is Intel and IOMMU is AMD)
April 28, 201610 yr Author ah ok. vt-d is enabled in the bios.... It must be something else that is causing those errors. I'm on 6.2.0-beta21 Interestingly: http://ark.intel.com/products/52214/Intel-Core-i7-2600K-Processor-8M-Cache-up-to-3_80-GHz says that my processor doesnt have vt-d!

April 28, 201610 yr I could be wrong but you should still be able to have VM's you just won't be able to pass-through. You will need to use VNC to access them.
April 28, 201610 yr That's all I need. I wonder what is causing the error then The error you are seeing is not really an error. It's always in the logs. You need to post more info if you want to get a solution. Diagnostic zip and xml is a minimum.
April 28, 201610 yr Author solved - its a problem with Chrome! Firefox seems to work (adblock maybe?) the real vnc wasnt working
March 21, 20206 yr I understand this is an old thread, but just in case anyone else like me comes across this - it can also be caused when you first start a new VM, and it's attempting to boot off the install ISO. You’ll get a "press any key to boot from CD" prompt, but only for a few seconds, then the boot fails and you get a shell prompt. If you don’t get in to VNC quickly enough, it's easy to miss that "press any key" prompt.
April 4, 20206 yr Just in case anyone else runs into this issue, Safari will not open VNC properly either and you'll get the three horizontal scrolling dots, when in all actuality, your VM is running just fine. As of right now, Chrome (80.0.3987.149) in Catalina 10.15.3/.4 is working.
