Lately without me doing any configuration change, except for updating the Proxmox host (7.4-17 now) and the LXC Guest Samba server, I ran into a huge headache with connecting from my Windows 11 SMB client to the above Samba server. Basically, whenever I tried to open the drive or browse the...

Hi, Our lab is installing a new system with EPYC CPUs and one Nvidia A100 GPU. I have experience with Proxmox over consumer grade hardware over the last couple years, but I have never tried so on a more enterprise setting. It would be great if you can help me with some questions I have: 1. Is...

Sorry if what I was wrong to do this in LAN, but I am trying to setup WebAuth to replace TOTP for my nodes within my LAN network. In DataCenter -- > Option --> WebAuth, I tried to set the domain name to the LAN IP of the node: https://192.168.1.4:8006 However, then when I tried to add for a...

I am trying to config my new Proxmox Backup Server (2.4-1) such that it can be put to sleep when not being used, and only wake up over the midnight to perform backups. While I tried to put it to sleep using systemctl suspend, while it does goes to sleep for maybe a few seconds, it instantly...

Sorry if this is not related to Proxmox, but I am out of idea with a recent passthrough related issue. I am trying to use some instruments through a PXI-E chassis. It is essentially a instrument chassis like eGPU box, which extends the PCI-E connections to outside of a workstation, by...

After I have changed the UID and GID for an LXC, I also changed the UID:GID on host for that image file (mounted by pct then chown). While I can boot up the LXC and everything seems to work, when I install any package into the LXC as LXC's root, these errors always show up Any idea what maybe...

Hi, I am trying to set up two unprivileged containers, one with SSH access, the second with a Samba server. Both LXCs have bind mount to the same directory on host. The idea is, I will drop files into the bind-mounted folder from a Windows client using WinSCP though the SSH LXC, and the files...

I am trying to setup a PC with the following spec: Intel C422 chipset W-2225 for CPU Running Proxmox 7.3-4, and I am installing 2 VMs with legacy BIOS for virtual routers, and 1 VM with OVMF and machine type q35 for a Windows 11 installation. All installed well, I then followed the wiki page...

Hi, Recently I purchased a new GPU for numerical work for my workstation. It was installed roughly 1.5 year ago and has been running PVE 6.4, running on a AMD Threadripper 3970X, with PSU being Corsair AX1600i. Here is the kernel version: Linux polaris 5.4.189-1-pve #1 SMP PVE 5.4.189-1 (Wed...

I am running Proxmox 6.4-13. Lately I am experiencing system freezing, in particular before it totally freezes out, it will display input/output error when doing df/nano/lsblk. I ruled out all add-on disks, leaving the system SSD to blame. Besides it being a hardware failure, I remember seeing...

This may not be a Proxmox issue as it could just be the motherboard, but here is my observation which I wonder if you have any clues. I am trying to boot Proxmox 7.0-11 headlessly after the initial installation. With the GPU still attached, everything works normally and I could access the...

I recent got a new build for using PVE, with the key components: AMD 2700X Gigabyte X570S UD Vega 56 PVE 7.0-11 After the installation, before setting up any VM, I installed lm-sensor and checked the temperature of various items. The GPU shows 44C and is actually only warm to touch. This temp...

I updated Proxmox via the GUI today, after a reboot I realized my LXC wireguard client can no longer connect to a wireguard server as usual. The journal shows the below: Jul 11 16:35:00 CSWG2 wg-quick[334]: [#] ip link add wg0 type wireguard Jul 11 16:35:00 CSWG2 wg-quick[341]: Error: Unknown...

I am setting up one VM to do plotting for Chia, it has the following disks: -3 pass-through 1TB SSDs -5 SATA 400GB SSDs as RAID0 in Proxmox, used as a directory and is assigned as virtual hard disk to the VM (volume set was 1800 GiB, after checking df -BGiB in Proxmox shell) -1 PCI-E RAID card...

With PVE 6.4-6 and ubuntu 20.04.2 as guest VM, I am trying to use memory ballooning. The system has 64 GB RAM and at the moment only 3 OS are running, 2 are using in total < 2 GB RAM, so most RAM is available for the ubuntu VM. I set the VM to have 8 GB minimum, and 48 GB as memory, with the...

I have a guest ubuntu 20.04.2 where I tried to pass two Kingston A2000 1TB to, this is done by passing them as PCI Device, with PCI-E flag checked. The advertized speed is up to 2000 MB/s write. With the drives empty, I found while read speed is 2000 MB/s as expected, the write speed is limited...

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...

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...

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...

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...
