coLinux 0.7.8 SMP? Yes or No?

    Hi All,

    I was hoping that someone here can clear up the SMP support story.  I have installed 0.7.8 on an i7 PC.

    Will the images that I use run SMP? I got the ubuntu 9.04 image running but from what I can see there is only 1 cpu.

    cat /proc/cpuinfo only has 1 CPU listed. Normally there would be 8.

    I tried to set COLINUX_NO_SMP_WORKAROUND=Y in the batch file that starts colinux-deamon.exe but that doesn't seem to have any affect.

    Can someone please give a summary on the state of the SMP? What can I expect? I want to use coLinux with CentOS as a replacement to cygwin.

    BTW, I have read the forum and mailing list but the SMP support is unclear.

    coLinux supports only one cpu for guest. There exist no SMP support for the Linux side.

    With 'COLINUX_NO_SMP_WORKAROUND=Y' coLinux runs on all processors. But, here it means on the host (Windows) side. Without this option the Windows task colinux-daemon.exe will claim only on CPU0.

    hi All,
    Does this mean that under 2 CPU machine on windows 2000 it can take 2nd PC… if so how do I do this?

    btw - I am stuck running Windows 2000 on my SGI 320 workstation as it is proprietary hardware and bios
