Hi there,
this is a first time here so hi to everyone!
I'm having a strange issue with a new machine i've set up. The setup is:
Host:
2x Xeon E5-2650v3 Hyperthreading enabled
128GB RAM DDR4 2133 ECC
RAID 1 with 480 gig Samsung SSD MZ7LM480HCHP on (Host OS, high IO storage, not used yet)
RAID-10 with 10k SAS drives (data drives for guests)
HW-Raid: MegaRAID MR9361-8i with BBU
Currently this machine hosts one single VM (planning to add some in the future)
We put some serious load on the guest from time to time and we really need all those threads.
Guest CPU Util:
Host CPU Util:
Since the host does literally nothing else then serving the guest I have no idea what is causing this amount of stealtime.
Any input is appreciated.
Thanks for your time guys.
