Hey dlandon, I had a quick question about the emulator pinning.
I've noticed on my system that the Dashboard's System Status in the unRAID webGUI can frequently show the first pair (0, topping out at 2400/2400MHz on my 8 core xeon. I know that you recommended using only the first pair for emulator pinning (even with multiple VMs), but I was curious if it's possible to emulator pin more than one pair per VM? Also, what would the xml for a VM like that look like?
I have all the other pairs (sans 0,1,8,9) isolated in the syslinux config.
I'm currently using this xml for the VM in question.
<emulatorpin cpuset='0,8'/>
Could I emulator pin more pairs using something like this?
<emulatorpin cpuset='0,1,8,9'/>
Bit of a side note; I've also noticed that though 1,9 isn't explicitly assigned to anything, that it idles around 2200/2200MHz since I isolated and pinned the other cpus. Normally they all rest at 1200/1200MHz.
