Public bug reported:
Hi!
QEMU stopped working after "[355023f2010c4df619d88a0dd7012b4b9c74c12c]
pc: add SMM property" on my server. It says "Guest has not initialized
the display (yet)." and nothing happens. But only if I use -enable-kvm.
However, the problem gone after I hardcoded pc_machine_is_smm_enabled()
to always return false (but I have little to no understanding of what
SMM really is).
CMD line that reproduces the issue: qemu-system-x86_64 -enable-kvm
-display curses . It doesn't work the server, but works perfectly on my
laptop :(.
I'm using Arch Linux with all updates.
Some info:
Linux machine 4.2.2-1-ARCH #1 SMP PREEMPT Tue Sep 29 22:21:33 CEST 2015 x86_64
GNU/Linux
Qemu-2.4.0 (tried HEAD as well)
CPU: Intel(R) Core(TM) i7 CPU 950 @ 3.07GHz
Some messages from dmesg, just in case:
[ 6.996297] kvm: VM_EXIT_LOAD_IA32_PERF_GLOBAL_CTRL does not work properly.
Using workaround
[ 6381.722990] kvm: zapping shadow pages for mmio generation wraparound
I'm more than happy to provide additional information if needed.
Cheers,
Alex
