[vbox-dev] Can't use more than one vCPU after upgradingtoVirtualBox 4.3.x

[Tal Aloni]

Thanks Frank,
I see 4 CPUs in the host Task Manager, which Windows API call do you suspect the issue lies with?

Hi Tal,

as I thought: You have a newer AMD processor and Windows returns the
wrong number of cores for your CPU: It returns 1 when your CPU has 4
physical cores. We use a Windows system function to determine the number
of physical cores. I think that's a Windows bug and we need to find
a workaround. To be able to assign more guest CPUs to your VMs you
can use 'VBoxManage modifyvm VM_NAME --cpus ...'.

Kind regards,

Frank
