June 24, 20179 yr Hello all, (tower-diagnostics-20170624-0950.zip) This is somewhat part 2 of a challenge I've been experiencing, now able to connect via vnc, I have 64 GBs of memory in this server and have setup several vms with base Windows Server 2016 and have assigned them 4-8Gbs of memory (to start). Regardless of memory assigned upon boot task manager read majority of memory allocated . Array is formatted as:BTRFS, VMs:Qcow2 . Drivers/Bus: VirtIO Operation seems fine but just very odd. Assigned 8 Gbs to newly deployed server , was using almost all, shutdown server and assigned 30GBs , same thing - used RAMmap to idetify that the additional memory is Driver locked? ** I am not sure if this is a result of making my array BTRFS as I never noticed this prior when the array was XFS, or something with the whole "bleeding edge beta thing". Thank you! Attached are images of what I am experiencing. tower-diagnostics-20170624-0950.zip Edited June 24, 20179 yr by Xtr diagnostics and typos, more info
June 24, 20179 yr Community Expert Really doubt it's related to btrfs, my Server 2012R2 VM has normal memory usage, using v6.4-rc6 and btrfs.

I'm going to create another 2016 vm but check before I load drivers as I realized that the memory allocation states "driver locked" - may be something with a VirtIO driver I loaded. If same result I think i have an iso of 2012R2 somewhere as well
June 24, 20179 yr Author Found the issue*, the VirtIO Balloon Driver really seems to live up to its name, which makes me wonder if this is the intended use of this driver or something, see attached for proof. Uninstalling driver (and deleting) returns to normal allocation. Found this: https://rwmj.wordpress.com/2010/07/17/virtio-balloon/ - can any fill me in on the downside/benefits of using or not using this driver? Edited June 24, 20179 yr by Xtr
June 24, 20179 yr From what I remember the min/max allocation have never really worked. It's been discussed in some threads a while ago. The advice have been to set min and max to the same.
