Either we need to help Vadim reproduce this so he can take a look. Vadim: were you able to reproduce this? Or someone interested in Windows driver debugging can see if they can debug this. The symptom is that the guest driver is placing invalid descriptors into the vring. QEMU tries to map the memory and finds the address is in a memory-mapped I/O region instead of a RAM region. Normally the vring descriptors only point into RAM, so this is a guest driver bug where the vring is being corrupted somehow. If anyone wants to take a look I can try to help guide them along the virtio-specifics. Stefan
