[Qemu-devel] [Bug 990364] Re: virtio_ioport_write: unexpected address 0x

It doesn't look like as a vritio-win driver problem. 
you get the following message 
"virtio_ioport_write: unexpected address 0x13 value 0x1"
because netkvm driver triggers BSOD event, which  happened in 
different stack, and then kills the hosting QEMU prccess
by writing to ISR register. 

In your case (minidumps in comments #1 and #11) BSOD
happened inside of Raw Input Thread, which usually caused
by all kind of key and mouse filters/loggers. 

Unfortunately minidump doesn't provide enough information
to troubleshoot such kind of problems. If it's possible - try disabling 
antivirus  and RDP on your system.

You received this bug notification because you are a member of qemu-
devel-ml, which is subscribed to QEMU.
