Hello All
I have a suddenly occurring BSOD on startup of a Windows XP 32bit VM on a Windows 10 64bit machine?
Is this something to do with the recent release? Log attached
Don.

Re: BSOD on Windows Guest
The VM's log shows that the VM 'hardware' keeps running, so the problem may not necessarily be with Virtualbox. Try troubleshooting the BSOD directly inside the XP OS itself using normal web-searchable Microsoft methods to determine the error code and how to fix it. Virtualbox logged a 7E error code.
One other thing, Hyper-V on the host is enabled. Since we don't know if it was enabled on previous working runs of the VM, though, this may not be the problem. Or Hyper-V could have gotten enabled by a Windows update at the same time as Virtualbox got updated, and might be interfering with Virtualbox. We have no data at this time to determine which. See HMR3Init: Attempting fall back to NEM (Hyper-V is active) to turn off Hyper-V if desired.
If you can downgrade to the previous version you had installed and the BSODs stop, and then you re-upgrade to the logged 6.1.36 and the BSODs start again, then I'd say yes. Otherwise, we have no data over which to speculate.DonVetOne wrote:Is this something to do with the recent release?

It seems it was the host "Hyper-V" setting causing the problem. Thanks.
What is the correct Paravirtualization setting for a Windows XP 32bit guest?

Re: BSOD on Windows Guest
It can be anything you like, because XP is way too old to use a hypervisor API. The Hyper-v API is AFAIK only usable by Win8 or later (not sure about server versions).DonVetOne wrote: What is the correct Paravirtualization setting for a Windows XP 32bit guest?
FYI: paravirtualization is a software interface that selects the "language" that VirtualBox will use to talk to the guest OS. So it has no function if the guest OS knows no such language (e.g. XP), and it has nothing to do with what language the host OS is using to talk to it's hypervisor.
