Red Hat Working To Improve Memory Tiering For QEMU VMs To Save RAM

The engineers are exploring various methods to enhance memory tiering specifically for QEMU virtual machines. Their primary goal is to utilize NVMe SSDs in more scenarios to reduce dependency on physical RAM, which has become increasingly expensive.

Memory Conservation

By implementing these improvements, Red Hat aims to address the challenge of sky-high memory pricing in the current market. The memory tiering optimization would allow QEMU VMs to operate more efficiently by utilizing faster storage as an extension of system memory.
