Unsure about whether 3 bugs are on KVM side or QEMU side

Unsure about whether 3 bugs are on KVM side or QEMU side

[Eric Li]

Hi,

I found 3 bugs while developing a micro-hypervisor using QEMU + KVM on
Linux. However, I am not sure whether I should report them to QEMU's
bug tracker or KVM's. Following https://www.linux-kvm.org/page/Bugs , I
am asking here.

Originally I thought that the bugs are in KVM, so I filed 2 of them in
KVM's bug tracker. But thanks to Jim Mattson's comment, I realized that
these bugs may be in QEMU.

Do you know whether the following bugs should be posted to QEMU or KVM?
For bug 1 and bug 2, if they should be posted to QEMU, should I close
these bugs in KVM and create a new bug in QEMU?

Bug 1: filed in https://bugzilla.kernel.org/show_bug.cgi?id=216002 .
This is an assertion error while debugging QEMU + KVM with GDB. The
guest is running a hypervisor (i.e. nested virtualization).

Bug 2: filed in https://bugzilla.kernel.org/show_bug.cgi?id=216003 .
This is another assertion error while debugging QEMU + KVM with GDB.
The guest is running Windows.

Bug 3: not filed yet. When I run a hypervisor as the guest, and the
hypervisor tries to boot Windows, I see the following error printed
