yes, but AFAIK, after the system reboot
these vcpu will change, are I correct?

show you tha arch diagram
Since , AFAIK, you can not assign specific vcpu to LDOM domain
True - but you can get the I/O domain to be where you want it by a
bit of cunning.
If we have a freshly installed system with a control domain to be
say 8 cpus it will use cpu 0-7. We want the I/O domain to be on
the second socket ( cpus 64-127) so we need to fill the gap with a
dummy domain.
ldm create dummy
ldm set-vcpu 56 dummy
ldm set-mem 1g dummy
ldm bind dummy
then create i/O domain
ldm create secondary
ldm set-vcpu 8 secondary
ldm set-mem 4g secondary
ldm bind secondary
then delete dummy
ldm unbond dummy
ldm destroy dummy.

IMHO,
you are chasing a rube goldberg!!

I am standing up an IO Domain LDOM on a

things in the documentation about Socket affinity and PCI

PCI_2 and 64 threads (1 socket), but am just wondering if
there's something
I should be doing to better align the threads with the PCI
bus, or am I chasing
a rube goldberg?
