Comment 11 for bug 1329956

I am no longer able to reproduce this issue on a fully-updated server. My guess is that the issue was fixed in the kernel somewhere between 3.12 and 4.0, but for all I know it could be a Qemu (or even Seabios) change. Here are details of my test that failed and the one that succeeded.

Breaks (VM hangs during boot after pressing ctrl-alt-del):
kernel 3.12.22
qemu-kvm-1.7.0-3.el6.x86_64
seabios-1.7.3.1-1.el6.noarch
Intel(R) Xeon(R) CPU E5-2667 v2 @ 3.30GHz

Works (VM reboots normally):
kernel 4.0.4
qemu-kvm-2.3.0-6.el7.centos.x86_64
seabios-bin-1.8.1-1.el7.centos.noarch
Intel(R) Xeon(R) CPU E5-2680 v2 @ 2.80GHz

I'd still like to narrow down the change that fixed it if possible.
