I have put in a bug report as recommended. The person helping me there is requesting: Could you get a backtrace of qemu crashing - this might be easiest if your distro records core dumps somewhere. I dont know how to do this. Can someone help me figure out 1)what this is and 2) how to do it so i can get this info to the bug report? also fyi for anyone interested, my bug report and conversation: https://bugs.launchpad.net/qemu/+bug/1821054

here is a copy of the syslog. The repeated lines delineate the lines written during the latest trial.

In reply to your second message, this is the error i get when i try to attach the pci bridge you specify.

in reply to your first message, the below is the only message i get.

I am trying to setup a XP vm with hardware passthrough of an old radeon 9250 and creative labs sound blaster card. I have the cards hooked to my unraid server via a pcie to dual pci adapter (example can be found here: https://www.aliexpress.com/item/Desktop-PCI-Express-PCI-e-to-PCI-Adapter-Card-PCIe-to-Dual-Pci-Slot-Expansion-Card/32849431927.html ). My IOMMU groups show the adapter, sound card and what i believe to be the two outputs of the graphics card all in the same group. I think this is fine as all the devices are to be passed to my vm. IOMMU group 15:[12d8:e111] 01:00.0 PCI bridge: Pericom Semiconductor PI7C9X111SL PCIe-to-PCI Reversible Bridge (rev 02) [1274:5880] 02:04.0 Multimedia audio controller: Ensoniq 5880B / Creative Labs CT5880 (rev 02) [1002:5960] 02:05.0 VGA compatible controller: Advanced Micro Devices, Inc.

[AMD/ATI] RV280 [Radeon 9200 PRO] (Secondary) (rev 01) however when i try to start the vm im greeted with a popup and the message in the title: "internal error: qemu unexpectedly closed the monitor" the syslog isnt much help either. I tried to start several times in succession so that the errors would be evident in the logs: Mar 7 20:57:52 unraid kernel: vfio-pci 0000:02:05.0: Refused to change power state, currently in D0 Mar 7
