[Qemu-devel] [Bug 1728256] Re: Memory corruption in Windows 10 guest / amd64

[Dmitrii Shcherbakov]

Got similar behavior with windows server 2012r2 VMs.

Environment:

Windows VMs error out and create a memory dump:

The computer has rebooted from a bugcheck.  The bugcheck was: 0x00000109
(0xa3a01f5891f186c5, 0xb3b72bdee47188a0, 0x0000032000000000,
0x0000000000000017). A dump was saved in: C:\Windows\MEMORY.DMP. Report
Id: 033018-31234-01.

Based on microsoft docs:

https://docs.microsoft.com/en-us/windows-hardware/drivers/debugger/bug-check-0x109---critical-structure-corruption
CRITICAL_STRUCTURE_CORRUPTION Parameters
Parameter  Description
1 Reserved
2 Reserved
3 Reserved
4 The type of the corrupted region. (See the following table later on this 
page.)

...
0x17 Local APIC modification <--- this


Which is the same as with other reports out there:

>From what I see the change was backported but there was no new build yet.

Title:
  Memory corruption in Windows 10 guest / amd64

Status in QEMU:
  New
Status in linux package in Ubuntu:
  Confirmed

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.
