Hi! I've created my LXC in a folder (/var/lib/lxc/218), so I could use the full capacity of the host's disk: pct create 218 /var/lib/vz/template/cache/oracle-linux-8-20220719.tar.xz --rootfs=/var/lib/lxc/218 --hostname w18 --net0 name=eth0,ip=10.0.0.18/24,gw=10.0.0.1,bridge=vmbr1 --memory 7196...

Hello! I use node directories for storing my LXC container data. This allows me to use the full disk space of the node more effectively (instead of carving out a part of it that might not be used fully). Here is the config of one of the LXC's: arch: amd64 features: fuse=1,nesting=1 hostname...

I would like to lock 1GBPS on my network cards that sometimes fall back to 100mbps. For now I'm using a custom-made bash script, but it would be amazing if network interface speeds could be assigned through the web interface.

Hello! I'm using a very old KVM system to access my datacenter and I've noticed that the proxmox installation interface is very sluggish: Perhaps it's possible to remove all gradients (or redo the interfaces in ncurses?). Also, the window barely fits into a 640x480 kvm window. Also, I have a...

Hello! I've just upgraded to proxmox 6.1 and installed the latest Centos 7 template (centos-7-default_20190926_amd64.tar.xz). When I enter the LXC and try to shut the Centos 7 down, it just won't. ps aux shows: USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND root...

I've just noticed that after rebooting a proxmox server, there are new lines added to /etc/hosts inside Centos containers. They look like this: ::1 localhost This is undesirable, since my containers have no ipv6 support (and I don't need them to have it). How can I disable this?

I use heartbeat to move the primary IP address between the eth0 interface of my 2 containers. For the internet connection to work, heartbeat requires the gateway to already be set in the interface configuration. When I set the gateway in the container settings and leave the IP address empty, it...

I created a Centos 6 container with a static network interface. However, the container's interface configuration file /etc/sysconfig/network-scripts/ifcfg-eth0 shows dhcp: This leads to a delayed load of eth1 which causes problems in my systems.

I've noticed that the default net.netfilter.nf_conntrack_max is too low and I was hitting connection problems too often. Dropped connections, connection failures, nasty stuff. I had to manually increase net.netfilter.nf_conntrack_max to 1000000000 in all my proxmox nodes. Perhaps, the staff...

I recently reinstalled my Proxmox 4.1 servers with Proxmox 4.4. I recreated the CTs with identical configuration and software. I've noticed a huge increase in swap usage. One of my servers actually crashed because it ran out of swap. Here is a graph from one server that is still alive: You...

I have a Centos 7 CT with 2 GB swap limit. But when I boot into it, it shows me the host's 8 GB available for swap. Weird?

I have 32 gb of memory which I shared in two CT's: 1. 2gb of RAM - Centos 6 for haproxy and nginx. 2. 29 gb of RAM - Centos 7 for Percona Cluster database. I've noticed high swapping on 29 gb VM in decided to stop it. And then I completely removed it from the system. When I SSH'ed into the...

Hi! I want to install proxmox on a group of SSD disks. I have a few questions. Does ZFS Raid support TRIM in Proxmox? I want to pool my 4 SSD drives into a Raid 0 pool. Is it possible to do "over-provisioning" (partition the space lower than the actual size of the drives)? From what I saw, the...

I am installing on a SSD drive and trying to save up every GB I can. I tried 3, 5 gigabytes and it tells me that space is not enough AFTER I fill out all other information. I have to restart the server and go through the installation again. It's such a frustration. First of all, why do you say...

I am transferring a LXC between proxmox nodes. When I run "pct restore ..." on the new node the process fails at the end with "unable to open file /etc/pve/firewall/103.fw.tmp.11828' - No such file or directory" and the restore is cancelled. The solution is simple - run "mkdir...

Hello, I am moving a LXC from one Proxmox node to another. I keep my LXCs in LVM instead of raw images. Backup was fine. But when I did a "pct restore" on the new node it tried to restore my backup to a raw image file in /var/lib/vz/images instead. How can I properly restore a .lzo lxc backup...

So I have been playing with my LXCs, turning them on and off (with "pxc start" and "pxc shutdown"). At one point "pxc start" started hanging for too long, so I stopped it with "ctrl-c". At the same time I couldn't connect via SSH access to my system any more (old connection was fine, new...

I am reinstalling proxmox and I would want to completely rewrite /dev/pve/root, while keeping /dev/pve/data and other logical volumes which keep my LXCs. As far as I understand, the current installer completely destroys the LV group and rewrites it from scratch, effectively destroying...

When installing latest proxmox through a iso everything is OK in Chrome. When installing through apt-get over a Debian Standard, Chrome responds ERR_EMPTY_RESPONSE while Firefox is OK: \ Any ideas?
