KVM Memory Leaking/Overhead?

So here is an interesting one - i have upgraded to rc2 and my memory issue seems to have calmed down rather a lot

 

So after upgrading i found one of my vm's (Jamie) would not boot due to some weird windows issue causing an update loop which kept failing, removing itself then applying again

 

So i did a fresh re-install and put avg free edition on the vm - the vm instantly lost internet access and explorer stopped working the second avg installed - it was so bad i couldn't shutdown, reboot or uninstall avg

 

Another windows 10 install later with no avg and everything seems to be working, this install has the newer virtio drivers and memory usage has dropped substantially

 

VM Cat: 10.5G Res - virtio from pre 6.1.9

VM Jamie: 10.1G Res - latest virtio driver

VM CCTV: 2483M Res - virtio from beta 23

 

Having the 3 vms running, my dockers and everything else i have been able to remove the swapfile plugin and my system is down to 24.8G memory usage

 

So i don't know what resolved this or helps to lower the usage but in total the following has happened since my memory usage was so high

 

  • Unraid updates
  • New windows install
  • New virtio drivers

 

 

While 2.1G overhead is a little over what i want i am very happy with it being this high and hopefully things will start to go down even more as time goes by

 

So all in i have now got a drop of 2.8G memory usage on just that 1 vm since reporting this issue

What was the result of your issues Jamie?  Did you ever figure out the KVM Memory leak (if that's what it was?)  I'm having a similar issue, but it's a single VM and within a week, it exhausts over 40gb of ram (mostly swap since the host system only has 8gb to start with), one major difference is my VM is a FreeBSD 8.1 legacy server that I virtualized.

 

Thanks,

Tyler.
