Hey guys, first post, long time creepy window watcher searching this forum and RingTFM. I have been searching over the past couple days and have not been able to figure out the answer to this question.
Since a virtual box instance is running out of a jail, shouldn't it not be able to over provision resources?
For example, I have a Plex jail, a virtual box jail for Mythbuntu, and am considering making another virtual box jail to be a transcoding virtual machine that watches a folder for my Bluray rips and for my recorded TV via Mythbuntu.
In the mythbuntu virtual box, I have limited this machine to 4 out of 8 CPUs (i guess it counts threads). This has seemed very reasonable for what is not a very challenged machine. Does this entirely rob the base OS of freenas of these cores? I assume no as this is all running in a jail and using the same kernel.
I am considering making a transcoding VM that just looks at a folder and transcodes it out. I would like to assign more cores to this machine so that it can chomp on through, but I do not want to ruin my box, obviously. When I allocate processing cores to this VM, should I assign it 6-8 cores out of 8?
While none of my jails or VMs are typically not doing a whole lot at the same time and I have never seen CPU use above 40% (when I was transcoding in the mythbuntu VM), I don't want to over provision resources. Does virtual box cpu allocation entirely rope off those cores? If I assign all the cores (8/8), does that rob Freenas of resources such that it has none? Would a scrub run at a higher priority than something in a jail?
The bottom line is that I don't want to be caught with my pants down if I am running a transcode during one of my bi-monthly scrubs (thanks for the mock schedule Cyberjock). So
To get it out of the way, I run the following system with the drives in a single raid z2 array (one vdev):
Mobo: Supermicro x9SRH-7TF
CPU: Xeon e5-1620 v2 with a large noctua cooler (4c, 8T)
ECC RAM: 48 GB (soon to be 64GB)
Drives: 6 x 4TB WD RED
PSU: Corsair AX 760
Case: Define R5
server has files, pictures, as well as media.
Thanks again to all, I really appreciate the help.
