Remoted in from work, setup fresh W11 LTSC vm, tested with and without PCI devices passed through, and no errors generated. I'm assuming something has happened to corrupt my original vdisk for my primary VM, so I'll go ahead and transfer that OS image to a new vdisk and test that out. I've seen some others posting about misc behavior of VMs after 7.3 update. Is it possible something with 7.3 borked some VMs? In regards to transferring OS to a new vdisk, what is best practice? Is it as simple as creating and attaching a vdisk2 to existing VM, using Macrium (or other mirroring software) to mirror OS to vdisk2, then replacing vdisk1 with vdisk2 as primary for VM?

Re-tested with no PCI devices passed through, just VNC for remote control. Still generated corruption errors in pool device status and same errors in the VM libvert logs. I suppose it'd be worthwhile to test if this occurs on a fresh VM as well. I can set one up later this evening and see what happens.

Sorry, this is my first post to the forum. I appreciate your patience. Attached the diags below. tower-diagnostics-20260527-0030.zip

Hoping for support on this seemingly niche issue. I don't see anyone else discussing this specific problem. I updated form 7.2.2 to 7.3 today, and immediately noticed an explosion of BTRFS 'corruption errors' being generated on my cache pool when my Windows 11 VM was running. After running Memtest (clean) and a scrub of my cache pool, I pulled everything off my cache and rebuilt it. During that time, I tried running my VM after moving the vDisk to my other SSD pool, and saw the same behavior: I just checked my libvert logs for the VM, and I have multiple errors there as well: I'm assuming something has changed with 7.3 that is causing my VM to generate these errors? Below is my XML, any help would be greatly appreciated! <?xml version='1.0' encoding='UTF-8'?> <domain type='kvm' id='1'> <name>Win11_LTSC-new</name> <uuid>6621b335-dc0a-455a-fd7c-5e7666d0e68c</uuid>
