as of today, I had to reboot Sophos again [:(]
so for peace of mind, I've re-enabled app control and filtering [:D]

Hi,
As William said there is not enough cpu cycles to run 4 VMs. The CPU is at least 4 years old. The UTM will need at least one dedicated core and 4gb of ram.
Sharing the dual cores between 4 VMs isn't going to work very well when you start downloading. To improve things you could disable IPS on your setup.
With such a under powered cpu you need to give the UTM at least 6 gb of ram so it won't swap much.

That's a weak cpu. how many other vm's are on that host? Also how many vcpus do you have assigned to the utm AND what are the percentages you ahve assigned?
hey William, yes it isn't the most powerful thing around but it works pretty well.
I have 2 vcpus assign to the vm, and if I understand you right about the percentages they're configured :
0% reserved
100% limit
relative weight: 100%

Honestly, it works pretty darn well... except for this one nag.,.. and after a reboot of the UTM, it is smooth.
The other Vms are "very" low resource machines... and the system responds quite well with 3 other VMs running (beside the Sophos).
While I wish I could replace the unit with something awesome, it's what I have available to me [:(]

nods anything would work better. Haswell and up even a dual core celeron would be better with the right nics and 4-8 gigs of ram..[:)] put the other vm's on minimum zero and weight of 75-50 depending on their priority. Make all of the other vm's max at 50%. Make the minimum reservation 50% and max 100 with 100% weight. Since you only ahve two physical core do not over subscribe the cpu cores per vm. give the UTM vm two and other others a maximu of 2 cores as well. Make sure you have a minimum of 4 gigs of ram dedicated to the vm.

The interesting thing is while Hyper-V manager shows the Sophos running at 90%+, and top confirms this, the host CPU utilization is low and other VMs are running fine.
I'll try tweaking the resource controls and see how this goes...
