  1. Forbid VM to be migrated (pin VM to host)

  7. About live migrations

    Is it possible to change VirtIO SCSI to virtio-blk? Does virtio-blk honor DISCARD? I don't find ih the web interface how to do it. I don't understand why the process of live disk migration has to fill with zeroes the target disk, it doesn't follow the thin LV approach of not using disk resources...
  8. About live migrations

    Hello, I'm a coworker of Conacious. Our setup is as follows: - Thin LV for all VM disks in all nodes (usually only one disk in one thin lv per VM) in source and target storages.

  12. Any experiences running Proxmox on a Hetzner server?

    I have a Proxmox cluster (3 nodes) + Ceph cluster (3 nodes) running fine on Hetzner with no private network. I use tinc in "bridge" mode to make my private network with multicast and it works, including migration. For setting up the Proxmox cluster I followed this guide...

    Hello. I have a production 3 node proxmox 4.1 cluster with an external RBD storage. The external RBD has 3 nodes, each one with a ceph monitor. The hostnames are ceph0{1,2,3}.mynetwork.com. The ceph cluster is healthy and everything works fine. My /etc/pve/storage.cfg is this: dir: local...
