Hi, I'm running a small lab at home (old PC hardware, no special server hardware). Until yesterday I used version 5.0, today I did an inplace upgrade to version 5.1. Since version 5.1 my server 2016 VMs are getting blue screens (server 2016 core and 2016 with GUI). With 5.0 everything ran stable. Blue screen is caused by ntoskrnl.exe bugcheck code 0x00000109. The host itself seems to run stable; Guest systems have virtio-win-0.1.141 drivers installed. Any idea where to look for a solution?
