I'm getting a BSOD (Critical_Structure_Corruption) on host after 30-90 minutes of using a vm. It never happens when not running a vm.


  • Virtualbox 6.0.6r130049 (Qt5.6.2)
  • RAM: 3192MB
  • Enabled I/O APIC
  • CPU: 1
  • Execution Cap: 80%
  • Enabled PAE/NX
  • Paravirtualization Interface: Legacy
  • Enabled VT-x/AMD-v
  • Enabled Nested Paging
  • Video Memory: 56MB
  • Monitor Count: 1
  • Graphics Controller: VBoxSVGA
  • Disabled 3D Acceleration and 2D Video Acceleration
  • Storage: SATA 32GB Dynamically Allocated
  • Guest OS: Windows 10 64 bits PRO
  • Guest Additions not installed (I tried with them installed, same problem).


  • Host OS: Windows 10 64 bits PRO
  • RAM: 16GB
  • CPU: i5 8400
  • GPU: GTX 1060 6GB

I don't know what to do, I can't use any vm. I tried searching about this error but got results that didn't help.

  • For starters, you have very little RAM to be running VMs. – user931000 Apr 26 '19 at 8:24
  • Nono, that's the setup for the guest. My bad I forgot the title, 1 sec I will fix it – roberto carlos Apr 26 '19 at 18:25
  • Did you disable Hyper-V feature and hypervisor in bcdedit? – Biswapriyo Apr 26 '19 at 18:34
  • I checked, it is disabled. Should I enable it? (I already enabled it on the BIOS) – roberto carlos Apr 26 '19 at 18:42
  • I mean, I enabled vt-x in BIOS. – roberto carlos Apr 26 '19 at 18:50

Found that this was causing the issue: https://github.com/hfiref0x/VBoxHardenedLoader/issues/4 As the link explains, if using the VBoxHardenedLoader from that page on Windows 10 it will be unstable unless you Code Sign the driver.

  • What is "this"? What steps did you follow to resolve it? While a link may be minimally helpful it gives little useful information here on this site. If the link dies or the page is deleted or moved for whatever reason then your answer may become useless. – Mokubai Apr 29 '19 at 7:26
  • Done, added explanation. Sorry! – roberto carlos Apr 29 '19 at 15:48
