Message-ID: <5079EB5B.8080102@hp.com> (raw)
Hello,
Wanted to get a clarification about KVM_MAX_VCPUS(currently set to 254)
in kvm_host.h file. The kvm_vcpu *vcpus array is sized based on KVM_MAX_VCPUS.
(i.e. a max of 254 elements in the array).
An 8bit APIC id should allow for 256 ID's. Reserving one for Broadcast should
leave 255 ID's. Is there one more ID reserved for some other purpose ? (hence
leading to KVM_MAX_VCPUS being set to 254 and not 255).
Thanks!
Vinod
