You need to unbind from vfio for the host to see the card. You can passthru without binding to vfio to a vm. If the vm is stopped then it will return bqck to the host. I believe it will support more than 1 gpu, but the plugin may just show the first. Maybe the driver vers may not support both.

Looks like disk1 cannot be mounted
Apr 9 07:29:35 Tower emhttpd: shcmd (40): mkdir -p /mnt/disk1
Apr 9 07:29:35 Tower emhttpd: /mnt/disk1 mount error: Unsupported partition layout
Apr 9 07:29:35 Tower emhttpd: shcmd (41): umount /mnt/disk1
Apr 9 07:29:35 Tower root: umount: /mnt/disk1: not mounted.
 

Did you reboot? try both

How did you install via KVM. There are loads of segfaults in the logs are you overclocking memory?
 
 
 

is it in use by unraid or mounted via UD?

Was checking on my issue I have logged on Gitlab  https://gitlab.com/qemu-project/qemu/-/issues/1270 I will see what they are looking for to be tested.
 
They seem to indicate it may be a change in the kernel from 5.15 to 5.16

Have you updated or removed the plugins that affect the dashboard 

Have you tried using SeaBios instead of OVMF?

Followed your suggestion and this has now been merged so will appear in the next RC..
Also includes support for missing USB devices so people can change to optional or remove.

This may help 
 

Will be used space on that disk/pool

open cmd line. cd /mnt/user/domains/"Windows 11"/
 
rm vdisk1.img

Are you able to post full diagnostics? 
 
You can add into the XML, there is an issue if the nic is removed then you cannot add back in from the GUI. Fixed in 6.12
 
example XML. The PCI nic may not show if in a IOMMU group that is shared.
 
    <interface type='bridge'>
      <mac address='52:54:00:18:64:6b'/>
      <source bridge='br0'/>
      <model type='virtio-net'/>
      <address type='pci' domain='0x0000' bus='0x01' slot='0x00' function='0x0'/>
    </interface>

Not sure if this is related. Its the qemu options at the bottom to increate to 64 from 32 default. 
 
 

What time did you start the VM in the logs was it around 1200 on the 30th, You are getting call traces with VMs
 
Are you on the latest BIOS?

Unraid uses eth0 so you have to change the order in network settings.
 
or enable bothing with both 1gb and 10gb. Then disconnect the 1gb now 10g should be active link.
 
 

fatlabel is the linux command, windows various options. Not sure why you need grub as syslinux should boot ok.
 
 

Windows should have a driver for this.

Sorry missing ' on this line.
but you also need to replace the XX. 
 
<mac address='52:54:00:91:9c:aa'/>

The guest agent error message is not a problem. It is used to get the IP addresses of the guest VM but requires you to install the guest agent on the VM.
 
I did look to see if the message can be suprresed but not found a way to do it yet.

Edit the VM goto XML mode.
 
Remove <memoryBacking> <source type='memfd'/> <access mode='shared'/> </memoryBacking> Replace with <memoryBacking> <nosharepages/> </memoryBacking>  

Add mapping


 
set on auto connect

You can create the share or change setting to a different one in vm settimgs

Have you tried pci=realloc=off
