    Most data storage with 64gb non-ecc and no HA

    Too late for me to go down the ECC road. I would have to start from scratch because my motherboard doesn't support it and I've already got 700 invested in my ram already. I may have to ditch ZFS all together and just do something like btrfs but I can't seem to get a straight answer if 60...

    Backup-Rechner aufsetzen

    PVE benötigt nur die Verbindung zum Backup Speicher. Wenn VMs daraus zurückgesichert werden, haben diese den gleichen Stand wie vorher (Netzwerk, RAM, etc.). Fallstricke gibt es trotzdem. Hat eine VM CPU type = host, kann das bei manchen Guests (insbesondere Windows) gerne mal zickig werden...

    PVE migration – Samba file server shadow copy: which technology should be used (vm with zfs vs. lxc with zfs vs. vm with ext4/lvm)?

    Our software development team needs a Windows Server VM to host AppVeyor, a CI/CD platform that requires Hyper-V to dynamically spin up and tear down Windows guest VMs for build and test pipelines. I've run many Windows Server VMs on this Proxmox host without issue, but this is my first time...

    For Windows to properly report used memory to PVE you need: - Virtio Balloon driver and service installed and running (installed and enabled automatically with the VirtIO ISO installer).

    PVE 9.1.1 Memory bug ? + Windows Server 2025 installation experience sharing

    It was pretty roller coaster for installing Windows Server 2025 on 9.1.1 Latest ISO won't boot, and eventually the evaluation ISO works! I almost wanted to use the thumb drive given by Microsoft because i also can't find the RTM ISO link. This seems to be a very common issue reported globally...

    Do you need to shutdown VMs to backup them with stop mode?

    That is what I thought, but I am not sure if this is entirely correct. In the logs you can see this, no matter if the VM was running or not, when using stop mode: INFO: scsi0: dirty-bitmap status: created new So there is some dirty-bitmap that gets created. How that is used? I have no idea and...
