Re: [libvirt] PATCH: Fix KVM maximum vCPU count
Hi, Dan
Thank you for commenting.
Of course, I agree your point
and that you are commiting it.
I am commenting it
just because 2 month is not old ago in my feeling.
Here Is the memo for my understanding.
(Since I am not familiar with KVM)
2007/07/19 kvm-30 Guest SMP support
(Parameter(KVM_MAX_VCPUS) changes from 1 to 4 in KVM-28)
2008/02/26 kvm-62 VCPUS changes 4 to 16
Thanks

If it increases to 32, then we should certainly check based on something
like KVM_API_VERSION. I just don't think its worth checking for the
ancient versions which only support 1 cpu because no one will be seriously
using them.
