April 28, 20224 yr So I am having an issue with my nvidia gpu that is passed through to my windows 10 VM. Everything was working fine, shut my machine down. Next time I boot it up, I get a black screen and my log file is full. I get this error in the VM log "2022-04-28T01:17:44.019508Z qemu-system-x86_64: vfio_region_write(0000:10:00.0:region1+0x158a80, 0xff2067b2ff2067b2,8) failed: Device or resource busy" when I check my Syslog, I have this error "Apr 27 21:17:44 Gallifrey kernel: vfio-pci 0000:10:00.0: BAR 1: can't reserve [mem 0xb0000000-0xbfffffff 64bit pref]" and it fills up the whole log file. Still pretty new to this, so if there is anything I need to post, some one please let me know. Any help would be appreciated gallifrey-syslog-20220428-0136.zip Edited April 28, 20224 yr by Liqwid_Kirk
April 28, 20224 yr Apr 27 21:01:11 Gallifrey kernel: pci 0000:10:00.0: BAR 1: assigned to efifb BAR1 is assigned to efifb, add parameter to your syslinux config video=efifb:off and reboot the server Search the forum for this, there are posts with more details. Edited April 28, 20224 yr by ghost82

Where do you add it in the syslinux config?
April 28, 20224 yr I don't want to sound rude, but...did you do a search in the forum? For example this post has also a screenshot: https://forums.unraid.net/topic/119572-passthrough-1050-ti-as-secondary-card/?do=findComment&comment=1096013 Note that in the screenshot it's wrong, parameters must be all in the same line, most probably your will be: append video=efifb:off initrd=/bzroot

It's all good, I am still pretty new to the OS and also trying to figure out how to search issues in the forum. I did see a post that mentioned the append part. I stubbed a pci-e controller a while ago and realized what to do. It works fine now. The windows VM boot just fine now. Thanks for all your help
