Arik Hadas has submitted this change and it was merged. Change subject: core: Change max vCPU count computation ...................................................................... core: Change max vCPU count computation Maximum vCPU count for a VM is currently determined by a defined absolute maximum limit and the number of cores and threads. However, on x86 the simple formula may cause overflow of an APIC ID limit due to the bit-based layout of the APIC ID value and then QEMU refuses to run the VM. With this patch we make sure that the value always fits into the APIC limits. See the bug report for explanation. In the future, when x2APIC will be used, we can remove the restriction.
