KVM Windows - Ballooning & Static Hugepages

Operating Systems & Open Source Linux
1

Hey there,

I am optimizing my Windows guest in KVM right now and have question I couldn't find a definitive answer to.

I have enabled 8x 1GB static Hugepages on boot. Since the space libvirt is using is pre-allocated, do I have any benefit in having the balloon driver installed? Seeing the memory usage on the host-side is the only thing I can think of right now.

Unless you know more than me I would just get rid of ballooning entirely.

Thanks in advance!

If you created 8GB of hugepages then that will always show up as used space using the free command. You'll have to verify they are being used by the VM.
