vmi-win-guid command timeout

I'm afraid running on KVM is not supported yet, as drakvuf project itself has some problems with KVM (drakvuf builds are created with --disable-kvm flag).
We have tested nested virtualization as in kvm => xen => windows and haven't managed to get it working (yet).

Hopefully in the future we will support it, but at the moment we don't support running on KVM.

@BonusPlay If he already succeeded to install Windows on vm-0, then there is a huge chance that his setup will actually work, so it would be good to debug this further.

@LANopop The error you have pasted looks like there is some trouble with LibVMI itself. What guest operating system are you using and what is the name/hash of ISO you are using?

@LANopop Ah, you wrote that it is Windows 10 x64. Could you point to the exact version of Win 10 ISO? It would be easier to reproduce this bug.

KVM Information (drakvuf is running here):
Linux debian 4.19.0-8-amd64 #1 SMP Debian 4.19.98-1+deb10u1 (2020-04-27) x86_64 GNU/Linux
debian 10.3
windows 10 x64 iso md5 hash: 23e397a21a9e01f141c64b7e1260314a (i had this iso stored somewhere and dont remember how i got it)

Proxmox Information (host system for kvm and lxc):
Kernel Version Linux 5.3.18-3-pve #1 SMP PVE 5.3.18-3
pve-manager/6.1-8/806edfe1
debian 10.3
CPU: 12 x Intel(R) Xeon(R) CPU D-1528 @ 1.90GHz (1 Socket)

the installation of windows itself took very long (at least 30 minutes). Also for some reason windows 7 x64 installation always blue screened after the installation was over and it started to boot.

For some reason Windows 7 doesn't play well when it's inside Xen which is inside KVM. According to your report, Windows 10 (surprisingly) seems to work under such setup.

For the MD5 sum you've provided, I see that this disk image is at least 5 years old. Could you try again with a more recent image?

Introspection tools are usually adjusted for the latest OS versions. Your particular bug is about LibVMI not being able to find Windows kernel in the memory. I suppose it may be so old and different that it simply could not detect it at all.

downloaded the newest version from the page you mentioned and after 30 minutes of me starring at the windows 10 logo i gave up. I dont think it is working :(

@LANopop Unfortunately, nested virtualization is very tricky and we don't officially support the setup with Xen nested inside KVM. This doesn't even have much to do with DRAKVUF Sandbox itself. If the VM is hanging during installation process, this is the problem with Xen, KVM or both.

If you have the possibility to use a dedicated server for it, DRAKVUF Sandbox would be most stable. We are also actively working to prepare a compatibility list, just to find out which popular cloud solutions (like Google Cloud Platform) are compatible with our sandbox and this would be published soon.

here is the windows 7 bluescreen if anyone is interested

Closing this for now, as nested virtualization is unfortunately not well supported due to Xen/KVM issues.
