VMware Virtual Machine Hosting

This is scumbag malware designed to take your machine hostage until you pay.

Here is the -quickest- way to eliminate this tediosity:

1. Register the scumware using this serial number: SL55J-T54YHJ61-YHG88

Once this is done it will allow you to now use your computer.

2. Open explorer and delete: C:Documents and SettingsAll UsersApplication Datadefender.exe

If the file is not there, search for: defender.exe and delete it.

3. Download SpyBot Search & Destroy and run it on your machine: http://www.safer-networking.org/en/download/

FreeBSD ZFS Settings On i386 Hardware

AMD64 Kernel FreeBSD machines are good about autotuning. i386, on the other hand, needs to be adjusted manually.

1. Rebuild your kernel
a. Disable/wipe all drivers you are not using or at least those you are highly unlikely to ever use.
b. Add: options KVA_PAGES=512
c. Recompile/Install new kernel

2. Add these parameters to /boot/loader.conf
a. vm.kmem_size=”1024M”
b. vm.kmem_size_max=”2048M”
c. vfs.zfs.arc_max=”256M”
d. vfs.zfs.vdev.cache.size=”40M”

This will get the machine online without it crashing with vm.kmem errors. ZFS will bring an untuned i386 machine down to its knees with kernel panics quickly!

Adjust the above variables to your tastes. My test platform is a Dual Xeon with 4GB of RAM.
