Windows 10 QEMU KVM Guest keeps pausing - apparently an I/O error

Hi all,

I've been working from home the last few months and my KVM has been absolutely fine, but this afternoon, after working fine in the morning and coming back from lunch, my KVM keeps pausing, citing an "I/O error" in virt-manager.

I can't see anything in /var/log/libvirt/qemu/Windows10.log, which is the most recent logfile.

This KVM has a PCI passthrough for my GPU.

I can't unpause, clicking the resume button does nothing. I can "resolve" the issue in one of two ways:

1) Reboot the host machine
2) Close the VM window, and re-open. When I click resume then, the VM crashes and completely powers off, and I have to start again.

Any ideas? I've accomplished nothing this afternoon due to this problem

Quick update - I think the disk which holds the .qcow2 file is full, so I'm currently shrinking the virtual disk image. Will update again if this helps
