High CPU usage during Openserver 5.0.7 installation

Postby cyruspy » 29. Jan 2010, 04:48

Hi, i'm seeing high values for CPU usage by "System" during Openserver installation. Is there any known workaround for "Other" guests?. I have Hardware Virtualization enabled, USB and IO/APIC disabled. The host is using IDE emulation. Any ideas?

Wow I didn't think Openserver would even run on VBox That's SCO Unix right?
If you are using VT-x/AMD-v then you should have IO APIC enabled.

Does it work? Even with the high CPU?
See section 1.4. Supported host operating systems of the VBox Users Guide.

Yes, it works. What should I look for in that section?, openSUSE is supported as host...

Oops I should have said supported guests.

Not a lot of UN*X stuff works in VBox. If it does it usually does not work well. Most of them don't even have guest additions available.
