Red Hat Bugzilla – Bug 1030290
incorrect description in qemu-kvm man page - 'SMP is supported with up to 255 CPUs.'
Last modified: 2014-05-27 16:17:46 EDT
Description of problem:
We actually support up to 160 CPUs while starting a qemu-kvm instance. But doc says the NO. is 255. Booting guest with CPUs greater than 160 leads core dumped.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
The QEMU man page is about QEMU as a whole, not about specific machine-types (which may have lower limits), or about specific accelerator limits (KVM has lower limits), or about what Red Hat supports.
QEMU itself supports up to 255 CPUs, but KVM and the rhel machine-types don't.
