Hello.
In my diploma project I'm trying to add VMX to qemu. It is first vmx
incarnation, without ept, unrestricted guest and other improvements.
It seems working in some way. Virtual Box can execute few hundreds of
instructions until crash, but it's tricky for me to build it completely to add

There is a misprint in the patch
https://lists.gnu.org/archive/html/qemu-devel/2014-11/msg01657.html . It cause
errors in guest work.
Here is the bugfix.

Obviously, there is a misprint in function implementation.

I'm understand your position.
But why in TCG undefined flags obviously change to zero in some cases?
For example:
af = 0; /* undefined */
It is not a part of Intel specification, what reason was apply that convention?

more than 1, OF of
eflags become undefined. Real CPUs does not change OF, if it is undefined. QEMU
do it anyway.
Emulated program can execute that test and after that can understand
