    Packet loss on VMs, but not with Proxmox directly

    I figured I'd come in and give an update to my problem. I'm uncertain why this hasn't bee a problem previously; however my router and AP extenders are using some form of spanning tree protocol that is incompatible with STP provided by Proxmox (Linux) and even my unmanaged switch. To solve my...

    Packet loss on VMs, but not with Proxmox directly

    I've found this rather newer and mention of Proxmox 8 thread on the subject. I'm not certain if my issue is exactly the same. I've been running a a pair of Proxmox workstations, they aren't in a pve cluster, for about 2 years. Just last week I physically upgraded one of the computers and...

    [TUTORIAL] Proxmox storage - Host to VM folder passthrough with 9p

    I wanted to come in and first thank you and second say that this seems to work fantastic on Gentoo, e.g. not Debian only (although I suspect the Debian only portion comes from copy pasta?) My use case is to keep a shared /home between my VMs.

    LXC Specific Commands For University Machine Learning Work Manager Cluster

    Reproducing my steps today, there is a step that is necessary. If you run /usr/bin/nvidia-container-cli and get a dlsym error (null) copying the libraries requires ldconfig to refresh the ld.so.cache file. This problem manifests as the container unable to start. If you ptc start <your_vmid>...

    LXC Specific Commands For University Machine Learning Work Manager Cluster

    In summary, it does appear that the nvidia hook script shipped with LXC automatically discovered and mounts the devices in from the host simply by setting the MIG's UUID in the environment.

    Good evening! Here is how I made this work. Forenote: The container must be unprivileged! The Nvidia script within the lxc distribution will exit 1 if it's privileged. Beginning: You must already have the nvidia drivers setup and your MIG devices working. Fix the /usr/share/lxc/hooks/nvidia...

    LXC Specific Commands For University Machine Learning Work Manager Cluster

    Good afternoon! I'm in need of running a specific LXC command and I'm not certain how to do this. I need to attach a GPU to a container using the gputype=mig, although I cannot find any examples of gputype=physical for Proxmox either. The Proxmox articles I've read seems to want to bind device...

    NVIDIA MIG (Multi-Instance GPU) on Proxmox

    Hello! I am actively working on this for a project at my employment. There are a lot of misunderstandings in this threat. First the A100 and A30 support MIG (Multi-Instance Graphics) which is not GRID. MIG partitions the A100 and A30s in to smaller contexts. GRID uses vGPU technology that create...

We're seeing a strange cap on backup speeds, around 125 MB/s regardless of source, Ceph, ZFS, local drives and destination with various protocols and destinations, NFS, Samba, Proxmox Backup Server, flash backed storage, spinning drives, SSD write...

    Guests Hang During Backup

    Hello, I've noticed that during a backup of a guest the guest becomes intermittently hung, dropping packets, crazy network lag of over 10 seconds and/or even occasionally getting host unreachable errors for the duration of the backup job. The source storage is Ceph and the destination storage is...
