    Trying to understand LXC RAM and SWAP allocation

    Thanks a lot, I think I am clear about how it allocates now. In this case, I will probably get a dedicated SSD for doing the SWAP in case we hit a high usage scenario.

    Trying to understand LXC RAM and SWAP allocation

    I have a workstation with 256 GB RAM, and by default the host has only 8 GB SWAP. With the two LXCs I have, as they can potentially use a lot of RAM, I committed 192 GB RAM and 64 GB SWAP to both. My question is, in a situation where both LXC reaches a high usage and they consume more than 256...

    Mounting/Connecting SMB automatically from unprivileged LXC without using fstab

    Thanks for the suggestion, that's actually the approach I have taken at the end. Yes I am using unprivileged LXC, and I found that data written by one LXC can only be read but not written by the other. As you mentioned, I might need to set the uid/gid, but if I just want data written by one LXC...

    Mounting/Connecting SMB automatically from unprivileged LXC without using fstab

    I am trying to connect to an SMB existing in another Proxmox guest, from both LXCs and VMs. The LXC clients are unprivileged, and when I add //192.168.11.20/store /mnt/store_mnt cifs username=store,password=password,_netdev 0 0 and execute mount -a It complained with an error suggesting a...

    Proxmox frozen randomly, any ideas?

    Thanks for the reply, it is so random that it just happened again - two hours ago before I have left my apartment it was working, now I can't access any server on it. The loss of internet (the NIC shown in the message) should not disable the management: My Windows PC was configured with a fixed...

    Proxmox frozen randomly, any ideas?

    Hi, I have been using Proxmox for a year now, and it has been running great on that machine (rock solid). Lately I put on a Windows Guest OS, but simultaneously true is I have not turned on that machine for a while as I relocated. In the past couple days after turning it back on, I have...

    Packet loss to/from Proxmox host/CT

    Thanks for the reply, I thought about that, but even the guest OS which obtains IP from DHCP also suffered from some degree of packet loss. (say, if I ping from a guest to the router at 192.168.100.1) Before concluding this issue being a Proxmox one, I will try to boot it from a USB to ubuntu to...

    Packet loss to/from Proxmox host/CT

    I have recently assembled a new workstation using Asus Zenith 2 Extreme which has multiple NICs. The intel one is what I am using for connecting to the host (for now): Intel® I211-AT, 1 x Gigabit LAN Controller(s) After a fresh installation of Proxmox, I realized that the Web GUI is often slow...

    Passing a LSI 9266-8i RAID array to unprivileged LXC

    Sorry if I missed the tutorial in the Wiki, I tried to find the method but couldn't seem to see it. I have a RAID 6 array under a PCI-E LSI 9266-8i RAID card. The RAID array forms a single 21 TB volume which is encrypted with LUKS, and it is normally locked in Proxmox host. At the moment, I...

    High performance way to share a NVMe RAID array across multiple VM guests

    Hi, I don't really have the need for speed regarding the title, but I can't help wondering what would be the most efficient (and maybe fastest) way to share an array across multiple VM/LXC guests. I am asking as I currently rely on a Linux Bridge which does not attach to physical port for...

    [SOLVED] Adding PCI Express Root bus device to the config file

    On this, I also wonder if something has been updated over the passthrough setting. In particular, I found that I could see IOMMU being enabled even before I have set the flags in /etc/default/grub. In fact, I can now pass my GPU and a LSI RAID card to two guests without touching those setting...

    [SOLVED] Adding PCI Express Root bus device to the config file

    Thanks Stefan for your reply and ideas, this is good and also sad to know [not a fix : ( ] I hope AMD could do something; it's hard to have a huge workstation while I cannot easily allocate the resource with VMs.

    [SOLVED] Adding PCI Express Root bus device to the config file

    Hello, Sorry if this question is very simple, but I have no idea about where to apply the said device in the title, that is from this link: https://forum.level1techs.com/t/increasing-vfio-vga-performance/133443 As an attempt to fix the AMD Reset Bug I knew that the config files of the VM sit...

    GPU Passthrough to ubuntu guest, rebooting guest will freeze the guest and glitch the host

    Thanks a lot, you have saved me hours of understanding the issue. However, it does seem like there has not been an actual fix for the AMD GPUs yet, as if they are not supposed to be passed to VMs. Interestingly, I have done GPU passthrough years ago (~2016) before I started using Proxmox. I was...

    GPU Passthrough to ubuntu guest, rebooting guest will freeze the guest and glitch the host

    Sorry for the long title, but the behaviour is a bit confusing so I said it in full. My spec is: Threadripper 1950X AMD X399 Taichi AMD Radeon Vii I clean installed Proxmox 6.2 and then also clean installed ubuntu server 20.04.1. I was trying to pass the GPU from Proxmox to the ubuntu guest. I...

    [SOLVED] Backup to Dropbox works for VM but not LXC

    Yes, I think the simplest solution is just to move the Dropbox folder out of root to my attached drive. Thanks again for your help!

    [SOLVED] Backup to Dropbox works for VM but not LXC

    Yes, I can confirm it solves my problem. Just a bit more: Apart from setting the destination folder to 777, I do have to set the /root and /root/Dropbox directories to 755, as I understand that the execution bit is required in order for the child directory to be written by other users. I might...

    [SOLVED] Backup to Dropbox works for VM but not LXC

    Thanks a lot for your reply. The container is indeed unprivileged and what you suggest is highly likely the case. I didn't know the backup was done by the root of the container, but not of the Proxmox host, and this is probably the reason.

    [SOLVED] Backup to Dropbox works for VM but not LXC

    Hi, I am trying to setup an automatic backup of the disk image to dropbox for my VM. First I install dropbox on my proxmox root, then I created a symlink folder where then I assign as the backup directory in the GUI. With this, I have no problem backing up a VM and have it uploaded to dropbox...
