but I wanted to understand a little more in depth how the memory management works. I did the tests in a cluster of 3 servers with a SAN storage, I tried to cut the power to a physical server and almost instantly the vm's that were configured with HA went to the next node, my question is, how do you manage the memory of each vm's? do you pre-share it in the other physical servers so that the memory status of each one is not lost? how do you manage the loss of the information that was not copied? is there any technical document of this implementation in proxmox?Regardspd: sorry for my english level, I hope my doubt is interpreted.
