Re: CS 4.2 KVM CONFIG_VIRTIO_BALLOON=yes
Thanks Nux, I am using over-provision, so I had to enable that feature in /boot/config--current-linux kernel. if I do rmmod virtio-balloon guest machines are able to see all RAM allocated to them but if I do modprobe virtio-balloon guest machines only see half of the RAM allocated. even if I turned over-provission off, guest machines only see half of RAM allocated to them.

Yeah, over-provisioning in KVM is a bit tricky. In 4.3 we'll have the option not to have the VMs memory size messed with and can use KSM for memory de-duplication. -- Sent from the Delta quadrant using Borg technology! Nux! www.nux.ro
