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.

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...

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...

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...

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...

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...

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...

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...

Thanks, I will instead do what you say.

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...

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...

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...

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.

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...

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...

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...

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!

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...

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.

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...
