Ticket #13500 (new defect)
Windows VirtualBox Process Priority support
|Reported by:||Jacob Klein||Owned by:|
|Version:||VirtualBox 4.3.18||Keywords:||process priority security|
BOINC runs CPU-instensive tasks (sometimes VirtualBox CPU-intensive tasks), typically at idle priority, but sometimes at below normal priority. The intent is to not interfere with the user's computing experience.
After the hardened security was added to VirtualBox for Windows (using VirtualBox 4.3.14+), the process priorities can no-longer be controlled. They run at Normal, with no way to change them (that I know of). This ends up degrading the user experience. I'm considering this a defect, since the hardened security changes broke something that was previously working great.
Please add some way to control the priorities of the VM processes that get instantiated -- Preferably available in the VirtualBox Manager UI, but for BOINC's purposes, VBoxManage command line parameters would work too I believe.
Thanks, Jacob Klein
