zyke Posted March 2, 2019 Share Posted March 2, 2019 (edited) I am running an i7-6700k with 64gb ram. in the first slot I have an MSI Geforce 970 4Gb, and in the second slot I have a Geforce 950. I am passing the 970 to the Windows VM, I've tried with both Windows 8.1 and 10, but I get extremely bad performance, laggy mouse and window movement. I've tried with reinstalling the drivers countless of times. I did try one of the tech roms, but just made the screen go black at boot. <?xml version='1.0' encoding='UTF-8'?> <domain type='kvm'> <name>Windows 10 - gaming</name> <uuid>0f8a944a-2f3b-1e40-b387-2ae19d8217c3</uuid> <metadata> <vmtemplate xmlns="unraid" name="Windows 10" icon="windows.png" os="windows10"/> </metadata> <memory unit='KiB'>8388608</memory> <currentMemory unit='KiB'>8388608</currentMemory> <memoryBacking> <nosharepages/> </memoryBacking> <vcpu placement='static'>2</vcpu> <cputune> <vcpupin vcpu='0' cpuset='0'/> <vcpupin vcpu='1' cpuset='2'/> </cputune> <os> <type arch='x86_64' machine='pc-i440fx-3.0'>hvm</type> <loader readonly='yes' type='pflash'>/usr/share/qemu/ovmf-x64/OVMF_CODE-pure-efi.fd</loader> <nvram>/etc/libvirt/qemu/nvram/0f8a944a-2f3b-1e40-b387-2ae19d8217c3_VARS-pure-efi.fd</nvram> </os> <features> <acpi/> <apic/> <hyperv> <relaxed state='on'/> <vapic state='on'/> <spinlocks state='on' retries='8191'/> <vendor_id state='on' value='none'/> </hyperv> </features> <cpu mode='host-passthrough' check='none'> <topology sockets='1' cores='1' threads='2'/> </cpu> <clock offset='localtime'> <timer name='hypervclock' present='yes'/> <timer name='hpet' present='no'/> </clock> <on_poweroff>destroy</on_poweroff> <on_reboot>restart</on_reboot> <on_crash>restart</on_crash> <devices> <emulator>/usr/local/sbin/qemu</emulator> <disk type='file' device='disk'> <driver name='qemu' type='raw' cache='writeback'/> <source file='/mnt/user/domains/Windows 10 - gaming/vdisk1.img'/> <target dev='hdc' bus='virtio'/> <boot order='1'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/> </disk> <disk type='file' device='cdrom'> <driver name='qemu' type='raw'/> <source file='/mnt/user/isos/Win10_1809Oct_EnglishInternational_x64.iso'/> <target dev='hda' bus='ide'/> <readonly/> <boot order='2'/> <address type='drive' controller='0' bus='0' target='0' unit='0'/> </disk> <disk type='file' device='cdrom'> <driver name='qemu' type='raw'/> <source file='/mnt/user/isos/virtio-win-0.1.160-1.iso'/> <target dev='hdb' bus='ide'/> <readonly/> <address type='drive' controller='0' bus='0' target='0' unit='1'/> </disk> <controller type='usb' index='0' model='ich9-ehci1'> <address type='pci' domain='0x0000' bus='0x00' slot='0x07' function='0x7'/> </controller> <controller type='usb' index='0' model='ich9-uhci1'> <master startport='0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x07' function='0x0' multifunction='on'/> </controller> <controller type='usb' index='0' model='ich9-uhci2'> <master startport='2'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x07' function='0x1'/> </controller> <controller type='usb' index='0' model='ich9-uhci3'> <master startport='4'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x07' function='0x2'/> </controller> <controller type='pci' index='0' model='pci-root'/> <controller type='ide' index='0'> <address type='pci' domain='0x0000' bus='0x00' slot='0x01' function='0x1'/> </controller> <controller type='virtio-serial' index='0'> <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/> </controller> <interface type='bridge'> <mac address='52:54:00:9d:a5:2e'/> <source bridge='br0'/> <model type='virtio'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x0'/> </interface> <serial type='pty'> <target type='isa-serial' port='0'> <model name='isa-serial'/> </target> </serial> <console type='pty'> <target type='serial' port='0'/> </console> <channel type='unix'> <target type='virtio' name='org.qemu.guest_agent.0'/> <address type='virtio-serial' controller='0' bus='0' port='1'/> </channel> <input type='mouse' bus='ps2'/> <input type='keyboard' bus='ps2'/> <hostdev mode='subsystem' type='pci' managed='yes'> <driver name='vfio'/> <source> <address domain='0x0000' bus='0x01' slot='0x00' function='0x0'/> </source> <address type='pci' domain='0x0000' bus='0x00' slot='0x05' function='0x0'/> </hostdev> <hostdev mode='subsystem' type='pci' managed='yes'> <driver name='vfio'/> <source> <address domain='0x0000' bus='0x01' slot='0x00' function='0x1'/> </source> <address type='pci' domain='0x0000' bus='0x00' slot='0x06' function='0x0'/> </hostdev> <hostdev mode='subsystem' type='usb' managed='no'> <source> <vendor id='0x046d'/> <product id='0xc248'/> </source> <address type='usb' bus='0' port='1'/> </hostdev> <hostdev mode='subsystem' type='usb' managed='no'> <source> <vendor id='0x046d'/> <product id='0xc332'/> </source> <address type='usb' bus='0' port='2'/> </hostdev> <hostdev mode='subsystem' type='usb' managed='no'> <source> <vendor id='0x1b1c'/> <product id='0x0a03'/> </source> <address type='usb' bus='0' port='3'/> </hostdev> <memballoon model='none'/> </devices> </domain> Let me know if you want me to dig up anything else that might help solve this issue. nas-diagnostics-20190302-0124.zip Edited March 2, 2019 by zyke Quote Link to comment
Warrentheo Posted March 2, 2019 Share Posted March 2, 2019 Your syslog is filled up with error's about IRQ's and call traces... Most likely the "Slowness" is the system trying its best to recover from these error's... Don't know if it is hardware failure or configuration issues... Use basic troubleshooting type steps (does it cause error's with no VM's running? does it cause error's with a simple Linux VM? Does it cause error's with Windows VM that has had all its devices and pass-throughs removed? Find something that doesn't cause errors and slowly build on top of that till you find the culprit... Also double check make sure that your host is setup correctly and BIOS is correctly configured... But basically your UnRaid Host needs to be working correctly before you can build a VM on top of it... Quote Link to comment

But basically your UnRaid Host needs to be working correctly before you can build a VM on top of it... So... I tried a lot of troubleshooting.. But I still got the IRQ problem. I saw something in the log which indicated that it got the wrong ROM. Which to me meant that it thought I was only running one GPU. So what I did was that I swapped the 970 and 950 on the motherboard. So that 950 is now in PCI-E 1 and 970 in PCI-E 2. This solved all my issues. But thanks to you I also got some other cleaning done that was problematic with the server. Big thanks for pointing me in the right direction.! TLDR: I have 2 GPU I set the GPU I wanted to use as passthrough on the PCI-E 2 rather than PCI-E1. Quote Link to comment
