since VBox 6.1, only 1 processor seems to work now..

I have been using this for years now, since you put it up, and always had 2 processors, 3GB of RAM. But now, whenever I try to use more than 1 processor, I'm getting a kernel panic.

I upgraded VBox from 6.0x to 6.1 -- I'm not sure if that is all that did it. I tried resetting the cpuid settings, etc, but either I'm doing it wrong somehow now, or it's not working like it it did before.

I tried a bit less RAM for no reason at all, but it didn't make any difference.

Here are the CPU settings in the Tiger.vbox file, in case you might spot what I'm doing wrong here:

      <CPU CpuProfile="Intel Pentium 4 3.00GHz">
        <PAE enabled="true"/>
        <LongMode enabled="false"/>
        <HardwareVirtExLargePages enabled="true"/>
        <CpuIdTree>
          <CpuIdLeaf id="0" eax="4" ebx="1970169159" ecx="1818588270" edx="1231384169"/>
          <CpuIdLeaf id="1" eax="3907" ebx="133120" ecx="4227858431" edx="4294967295"/>
          <CpuIdLeaf id="2147483649" eax="0" ebx="0" ecx="4294967295" edx="4294967295"/>
        </CpuIdTree>
      </CPU>
      <Memory RAMSize="2048"/>

or maybe it's just Virtualbox 6.1 for some reason doesn't support 2 processors...

anyway, it still works great, but it's nice to have the extra processor (or more?) if possible someday.
