Or I'm hoping to disallow it if possible though. I'm not sure we're in a position to do this right now. The current API has always (for good or bad reasons) been per-vcpu as it is tied to the vcpu initialisation. However, once we move to a sysreg-based API to control the vcpu features, we can revisit this and say that some features have a VM-wide effect if the vcpus have been created with some special flag (or some other TBD mechanism). Thanks, M. -- Without deviation from the norm, progress is not possible. _______________________________________________ kvmarm mailing list kvmarm@xxxxxxxxxxxxxxxxxxxxx https://lists.cs.columbia.edu/mailman/listinfo/kvmarm
