Dear QEMU developers, I am a Ph.D. student in Penn State. And we are currently working on a project that needs to fork multiple instances of a same VM instance with exactly same state (e.g., memory layout, registers, etc.) in a very efficient way. Snapshot is too heavy for us because it needs to dump the memory state to the filesystem so that reverting is possible sometime later. Our project does not need to revert a VM to a previous snapshot but lively clone (or fork) multiple instances and make them run at the same time. Do you happen to know if it's possible to do this? What we are envisioning is copy-on-write would happen both on disks (e.g., qcow2) and memory state (e.g., physical pages).
Thanks, Xinyang -- Xinyang GE Department of Computer Science & Engineering The Pennsylvania State University Homepage: http://www.cse.psu.edu/~xxg113/
