comment tuning tips for CPU load for OpenBSD guest on qemu-kvm Server
You're using a very long list of options on qemu, so I don't know how to help you. But I suggest to change -cpu to qemu64,+x2apic and every driver to virtio.

Can you add the version to CentOS, FreeBSD and OpenBSD? The dmesg of OpenBSD would be useful.

comment Linux: Why does the CPU frequency fluctuate when using the performance governor?
Another trick: use ´lsmod´ to list the modules loaded by the kernel, blacklist every module related to CPU speed scaling/p-state/c-states/whatever and reboot the machine. Search "blacklist kernel modules".

comment How to disable perf subsystem in Linux kernel?
The symbol -*- does mean that some subsystem depends of the perf module. Help shows the tree of dependencies which you need to disable to change the option to [*] or [M].

comment OpenBSD Apache version 1.3.29?
The answer of Krist is the correct one. Just a side comment. # pkg_info -Q apache-httpd -> apache-httpd-2.2.23. Apache2 is available from packages. The OpenBSD developers are focused now in nginx. nginx is installed by default.

Good point. I only need convert lists of IPs and rules like allow and drop. No more.

comment Portable firewall rules for Linux and Free/Net/Open/DragonFlyBSD
Because is for an automatic script and the rules will be in a central server. I don't need extract the conversion code, I think the conversion is easy but I would like a well tested tool.

comment Is it possible to hardware accelerate LUKS encryption?
What is your processor? The last models of Intel has AES-NI and VIA has had cryptographic hardware for years. Intel (I dont' know AMD) has especial optimizations for AES gcc.gnu.org/onlinedocs/gcc/i386-and-x86_002d64-Options.html .
