I've also had the exact symptoms and issues you've described. I have also noticed that the VM would BSOD with the CRITICAL_STRUCTURE_CORRUPTION message when the host system would read VM memory from swap.
After disabling swap on the host system I've completely managed to eliminate this BSOD issue. Hopefully it's also applicable to your system so you can atleast figure out how to move forward. -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1728256 Title: Memory corruption in Windows 10 guest / amd64 Status in QEMU: New Bug description: I have a Win 10 Pro x64 guest inside a qemu/kvm running on an Arch x86_64 host. The VM has a physical GPU passed through, as well as the physical USB controllers, as well as a dedicated SSD attached via SATA; you can find the complete libvirt xml here: https://pastebin.com/U1ZAXBNg I built qemu from source using the qemu-minimal-git AUR package; you can find the build script here: https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=qemu-minimal-git (if you aren't familiar with Arch, this is essentially a bash script where build() and package() are run to build the files, and then install them into the $pkgdir to later tar them up.) Starting with qemu v2.10.0, Windows crashes randomly with a bluescreen about CRITICAL_STRUCTURE_CORRUPTION. I also tested the git heads f90ea7ba7c, 861cd431c9 and e822e81e35, before I went back to v2.9.0, which is running stable for over 50 hours right now. During my tests I found that locking the memory pages alleviates the problem somewhat, but never completely avoids it. However, with the crashes occuring randomly, that could as well be false conclusions; I had crashes within minutes after boot with that too. I will now start `git bisect`ing; if you have any other suggestions on what I could try or possible patches feel free to leave them with me.
