Additional vCPU's not appearing on 32bit guest

Post by omega1 »

Hello,

I have a Windows 7 Pro 64bit Host with a Debian 32bit Guest.

I have added via settings an additional CPU but it is not showing up in Debian (via htop for example).

To add additional vCPU's I shut down the VM and changed the number of vCPU's in settings and powered it back up again, but the guest VM still reports only 1 vCPU.

I've read a few bits about this, but do not fuly understand how to have the additional vCPU's to be recognized by the guest.

I think the issue here is that the guest is 32bit as I tried the same thing on a 64bit guest and the vCPU's change as I make changes in settings.

Is this something I can resolve or not?

Thanks

Post the guests log file ( as an attachment ). Right click on the guest in the Main Manager then click show log. Save and post as an attachment. Compress if it is too large to post.
