#MacOsX : Mavericks Improve Virtual Machine Graphic Performance

I have made a short benchmark comparison of Parallels vs Fusion 5.0 HERE. VMWare Fusion has reached version 5.0.3, but it looks like VMWare has become lazy and those updates are not worth mentioning. However Apple released Mavericks recently, with an updated graphic stack which has slightly better graphics performance:

Component Lion/Mountain Lion Mavericks
Processor: 4.4 4.4
Memory (RAM): 5.5 5.5
Graphics: 5.0 5.0
Gaming graphics: 4.2 4.3
Primary hard disk: 7.7 7.7

Moreover, VMs seem to boot much faster under Mac Os X Mavericks.

N.B. you need to update VMWare Fusion to version 5.0.3 in order to have the best experience in Mavericks (or install VMWare Fusion 6).

#VMware Fusion : Fix Ubuntu Linux “Host SMBus controller not enabled!” [UPDATED]

Ubuntu guest instances in VMware sometimes come up with the boot error message:

piix4_smbus 0000:00:007.3: Host SMBus controller not enabled!

This error is being caused because VMware doesn’t actually provide that level interface for CPU access, but Ubuntu try to load the kernel module anyway.

How to fix it:

  • sudo nano /etc/modprobe.d/blacklist.conf
  • add the line:
    blacklist i2c-piix4
  • reboot

NOTE: for older versions use blacklist i2c_piix4 instead.
NOTE: it works both in VMWare Fusion 5 and 6, and Ubuntu LTS 12.04 and 14.04
