Hello,
I've recently changed over from TrueNAS Core 12.x to TrueNAS Scale 21.08 BETA.1.
At the moment I'm loving the new build.
The TrueNAS build is a physical install with a total of 64GB RAM installed in the machine, this is confirmed with the dashboard and console memory reports.
I have been noticing an potential issue with the memory utilisation discrepancy between the front dashboard Memory display/reporting memory graph and the virtualization memory display.
On the dashboard the Free Memory is showing 15GB~ free and the reporting Memory Physical Memory utilization is also showing 15GB~ free.
However, when I go over to the virtualization menu the page displays "Available Memory: 0.00 bytes - Caution: Allocating too much memory can slow the system or prevent VMs from running". It will allow me to create new machines, but it does display an message warning about the low memory.
I have also ran the free memory command on the console which confirms the dashboard and reporting figure.
I'm running a total of six virtual machines.
1 - 8GB RAM - Microsoft Server 2019
2 - 4GB RAM - Microsoft Server 2019
3 - 2GB RAM - Ubuntu 18.04
4 - 1GB RAM - Ubuntu 18.04
5 - 8GB RAM - Microsoft Server 2019
6 - 4GB RAM - Ubuntu 18.04
Totalling 27GB assigned to the virtual machines.
All the virtual machines have the guest software installed, either via apt-get or the microsoft virtio 1.90 software package.
Is this as expected from the system or should the Virtualization page show the same as the Memory being reported by the system?
thanks
Gavin.
