VMs Crashing

[Mike86]

Hello,

I had a problem where none of my VMs would launch -- getting different errors such as "Unable to load header file", and "Access Denied". After updating to the latest version of Virtualbox Manager (7.0.12) the problem seemed to be fixed -- I could open and use the VMs. But after a short while the two VMs I had open froze and were no longer usable. I have attached the log and any help is appreciated.

One thing that may or may not be involved: the Extension Pacl is not matched (EP version must match the host Virtualbox version):

00:00:07.206300 VirtualBox VM 7.0.12 r159484 win.amd64 (Oct 12 2023 19:53:29) release log
00:00:07.363721 Installed Extension Packs:
00:00:07.363739 Oracle VM VirtualBox Extension Pack (Version: 6.1.26 r145957; VRDE Module: VBoxVRDP; Crypto Module: unusable because of 'VBoxExtPackVMRegister returned VERR_VERSION_MISMATCH, pReg=0000000000000000 ErrInfo='Helper version mismatch - expected 0x3 got 0x50000'')

The OS inside the VM BSODs:

00:21:50.718973 GIM: HyperV: Guest indicates a fatal condition! P0=0x109 P1=0xa39fc3dc2c38db2e P2=0xb3b6d0627ebb3e92 P3=0x6 P4=0x18

The VM "hardware" stays running, so maybe the problem is inside the OS? Try a new fresh install in a new VM, no need ot activate. See if the new OS stays running.

Thanks, I've updated the Extension Pack and will see if that fixes the problem. Still not sure why I ran into the initial problem when the Extension Pack version matched the VBox Manager I was running.
