[Solved] Installing Windows 10

[curano]

I found the sha1 checksums on the Microsoft Website.

Both checksums are the same.

The download is correct !!!

The basic question - what the heck is going on here...

Well, if there's nothing wrong with the ISO, then I guess that leaves something wrong on the host. Any unusual host software installed?, that might be using VT-x and not tidying up correctly after itself? And of course the lack of memory is always a concern.

Incidentally, there may be a clue in the log, just before the guru meditation :-

00:00:50.057073 IEM: wrmsr(0xc0000080,0x0`00000800) -> #GP(0)

This is a warning that somebody tried to write to a I/O register (0xc0000080), leading to a general protection fault. However the former doesn't look like a register number to me, it's obviously an exception number. I don't know if that's the guest bug, or just a consequence of triple faulting.

I simply don't what kind of software is using VT-x, so I can't answer that question.
Can you give me a hint, please ?

Thanks

I'm no expert on VT-x usage on Linux hosts. On Windows it would be other VM platforms, some antivirus app, system level debuggers.

Did you also try to set the guest to only two or three virtual CPUs, leaving some of your four physical CPU cores free for the host to handle the VM?

[curano]

The guest is set to 1 virtual CPU only

[Martin]

Sorry, the first of your logs showed numcpus=4

[curano]

Yup, but the latest shows 1 cpu, because I did set up a new guest without modifications

Just some news:

I installed Fedora 24 from scratch onto my laptop (my test computer).
After that I installed Virtualbox 5.0.24.
A guest Windows 10.
The installation of Windows 10 went smoothly without any troubles.

Fedora 24 installed on my Workstation is an upgrade from F21 -> F22 -> F23 to F24.
It seems that some stuff is not the same as with a fresh installation.

The errors have nothing to do with Virtualbox.

Thanks for your help!

Thanks for reporting back.

I mounted the ISO file directly.
Still the same problem.
I uploaded the logs again

Your host kernel does not support PAE / NX but your guest requires Windows 10. I think using a PAE kernel on the host should fix your problem.
