I have installed OpenSolaris 052008 within a VM on Virtualbox-2.0.4. When I bootup the VM I'll get the following message:
NOTICE: MPO disabled because memory is interleaved

BIOS microcode patch for AMD Opteron erratum 131 was not detected (I forget the rest)

I had also installed Solaris10u6 on another VM and I'll get the first line message only. Are either of these a serious problem and how can I go about fixing both?

Also, I have found that the Solaris10u6 will not boot when I have the VT-x/AMD-V option set, in fact during the install when it went to reboot it hung, yet OpenSolaris has trouble running if the same option is not set.

My physical machine is based on a Gig-A-Byte MoBo with an AMD Athlon X2 64 with 4GB RAM. The OS=Fedora 9, uname -r; 2.6.27.5-37.fc9.x86_64. I thought that using the 64bit version of Virtualbox that you had to have hdwe virtualization enabled in the BIOS as well as the option selected for VM options for 64bit guest OSes to work properly?

Hi,

The MPO error is not a worry, the Memory Placement Optimization (MPO) is ignored as the memory is interleaved and therefore already Optimized by the hardware.

I'm assuming that AMD have some BIOS patch which you need to apply to the Hardware which the OS needs, but will work without it. It wojuld be best to have a look on the Manu's site for the patch as it should improve the systems stability.

Stuart.

What about the 2nd message of the erratum 131 error, or is that what you are referring to in your 2nd sentence?

"I'm assuming that AMD have some BIOS patch which you need to apply to the Hardware which the OS needs, but will work without it. It wojuld be best to have a look on the Manu's site for the patch as it should improve the systems stability."

Also, do you know why I don't get a reboot option in the shutdown dialog?
