    Azure optimization on proxmox

    Hi, I'm not sure this topic goes in this place but I'm sure it can be useful for sure. Some time ago I installed a virtual machine with azure with windows server 2019. Everything perfect, in fact I made a copy of that machine and imported it into my proxmox that I have for testing. I was...

    Does using VIRTIO SINGLE improve backup speed?

    Hi, Just a quick question. Can the speed of snapshots be increased by using paravirtualized hardware? For instance, VIRTIO Single with io-tread performance is better than IDE drives.

    [SOLVED] How can I specifiy a nominal speed of a kvm virtio NIC?

    Good morning, while expanding monitoring of my PVE systems I am stumbling over a (for me) problematic detail: the reported speed of a virtual NIC is always "10", which means 10 MBit/s. Specifically the host tells me this for any VM: root@pm1:~# cat /sys/class/net/tap110i0/speed 10 Just for...

    Limit PBS backup bandwith speed

    Hello, Is there a way to limit the speed at which PBS backups our servers ? I'm asking because it takes all our NIC bandwith which make our VM pretty much unreachable during the backup schedule. I've tried to edit /etc/vzdump.conf but it seems to ignore it when using PBS. Thanks

    [SOLVED] Speedtest-cli: Upload Speed is Capped Because the Kernel Uses BBR

    BBR seems to be the reason for upload speeds limited to 4.17Mbps when using speedtest-cli on kernel >= 4.9. See https://github.com/sivel/speedtest-cli/issues/605 Until this is resolved, use iperf to test upload speeds. PS: This is not a tutorial, but it is surely not a question.

    Benchmark: ZFS vs mdraid + ext4 + qcow2

    After fighting with ZFS memory hunger, poor performance, and random reboots, I just have replaced it with mdraid (raid1), ext4, and simple qcow2 images for the VMs, stored in the ext4 file system. This setup should be the least efficient because of the multiple layers of abstraction (md and...

    Hi there, Consider a 3 node setup with each node having 2x 10GB & 6x 1GB Nic. Is it more interesting to speedup replication between the nodes using 10GB interconnects and have the VM's communicate on 1GB (scenario 1) or is it more interesting to speed up VM <—> desktop access (scenario 2) My...
