vzkernel (RHEL6) 042stab081.8 + vzctl/vzctl-core 4.6-1 Released (10/29/13)
I'm testing the new vzctl offsite this weekend. I can't say that I'm excited about the implementation of vzoversell/vm_overcommit parameters. Easily bypassed I'm sure, though I still need to read through the manpages to learn a bit more. I'm particularly excited about the secondary UBC parameter support under vswap. Under certain circumstances or client request I've been setting these parameters manually and modifying the individual $CTID.conf and then cloning it as ve-$CTID.conf-sample to prevent the control panel from overwriting the custom configs.
( @alons, Can you please submit a feature request to your team to build, test, and eventually release support for manual additions/changes to privvmpages/lockedpages/vmguarpages/oomguarpages please? These parameters are not definable by the admin in the existing UBC configuration of Virtualizor 2.3.7. I believe I addressed some UBC concerns with Virtualizor you in my PM to you in early October )

Sir, these variables are used to calculate the RAM of the VPS.
Tampering with these variables can cause a VM to go down.
We avoided adding these variables for the fact that some admins might accidentally set them.
If you want then we will add it.
