# \[PATCH v2 3/6\] KVM: PPC: Cap KVM\_CAP\_NR\_VCPUS by KVM\_CAP\_MAX\_VCPUS - From: Vitaly Kuznetsov \ - Date: 2021-11-16 16:35:52 - List: linux-mips - Page: https://ratatoskr.run/linux-mips/2021/11/1576599 - Thread: https://ratatoskr.run/kvm/2021/11/1576596/t.md ```text It doesn't make sense to return the recommended maximum number of vCPUs which exceeds the maximum possible number of vCPUs.
