work.
1) Enforce KVM_CAP_NR_VCPUS <= KVM_CAP_MAX_VCPUS rule on all
architectures. [Sean Christopherson]
2) Make KVM_CAP_NR_VCPUS return num_online_cpus() and not an arbitrary
value of '710' on x86.
Everything but x86 was only 'eyeball tested', the change is trivial
but sorry in advance if I screwed up)
Christian, can you look at this for s390? Returning a fixed value seems wrong for KVM_CAP_NR_VCPUS.
will do. (Sorry I was OOO the last days).
Thanks,
Paolo
