piix4_smbus 0000:00:07.3: Host SMBus controller not enabled!

При переносе VM с  CentOS 6.3 с хоста ESXi 4.1 (Intel) на хост ESXi 5.1 (AMD) при загрузке выскакивает ошибка:

kernel: piix4_smbus 0000:00:07.3: Host SMBus controller not enabled!

Аналогично появилось сообщение в CentOS 6.x при upgrad с ESX4.0 на ESXi5.1 на серверах с процессором Intel

как вариант: 
i'm using virtualbox and not vmware, but i think this doesn't matter at all.
since the vm has no smbus, but ubuntu seems to always load the smbus module at boot, the fix is straightforward:

Code:

lsmod | grep i2c_piix4

and if you see the module is loaded, just blacklist it in /etc/modprobe.d/blacklist.conf, by adding:

Code:

blacklist i2c_piix4

at the end of the file (or anywhere). (eventually update your initramfs too: update-initramfs -u -k all)
that's all.
