I was checking the new version of Proxmox, when I noticed there is an option to enable 2FA; (see the docs) It works really fine, but then I realized my colleague’s probably don’t have the key. To disable however, I couldn’t find it online; So I digged in the guts of Proxmox /etc/pve/user.cfg there is […]

Finally got time to give Centos 8 a spin in a Proxmox Linux container (lxc); I downloaded the template, and started a container only to find its not possible : extracting archive ‘/var/lib/vz/template/cache/centos-8-default_20191016_amd64.tar.xz’ Total bytes read: 673566720 (643MiB, 37MiB/s) Detected container architecture: amd64 TASK ERROR: unable to create CT 100 – unsupported centos release ‘CentOS […]
I’m a long time user of Proxmox (a few years), and recently I had the chance to upgrade an by-now ancient Proxmox 3.4 to current 5.2. In that time frame the developers have changed from OpenVZ to LXC and made a script to migrate the data. One key element however, mounting (remote) NFS shares are […]
A small list for important Proxmox files & directories. For LXC (Linux containers) : config: /var/lib/lxc/$ct_id/config For KVM (Kernel-based Virtual Machine, mostly Windows machines) config: /etc/pve/qemu-server/$kvm_id.conf Cluster files (if you use Proxmox cluster) per node configuration : /etc/pve/nodes/$node_name/* Location of the ISO files that can then be loaded from the web interface : /var/lib/vz/template/iso/
Woohoo, Proxmox VE 5.0 has been released, this version is based on Debian 9. (Linux Kernel 4.10) It includes allot of new features, but sadly updates are still pointing to the enterprise repository for updates. This results in ugly error message when trying apt-get update such as : W: The repository ‘https://enterprise.proxmox.com/debian/pve stretch Release’ does not […]
When installing apcupsd on proxmox (similar to centos) I received this error : Error contacting apcupsd @ localhost:3551: Connection refused When running apcaccess. I got more info on the error using checking the service status : [email protected]:~# service apcupsd status ● apcupsd.service – LSB: Starts apcupsd daemon Loaded: loaded (/etc/init.d/apcupsd) Active: active (exited) since Thu 2017-05-11 […]
I got this weird error, which -to be fair- I haven’t exactly found out why it happens but I found a way around it. If you ever figure out how please let me know. There are some markers of this issue : Trying to log in remote, seems to work but ends up with : […]
After upgrading the latest proxmox; (apt-get update && apt-get upgrade) I received this error : Errors were encountered while processing: pve-manager E: Sub-process /usr/bin/dpkg returned an error code (1)
Hit by this little bugger this morning, while trying to move a virtual machine from proxmox 3.4 to 4.4. This was the only VM on the machine, so I was surprised. (Never seen this before) Could not access KVM kernel module: No such file or directory failed to initialize KVM: No such file or directory […]
Some time ago, I tried to create a VM on a RAID6 machine, getting this weird error when the virtual disk was made : file system may not support O_DIRECT The solution is to put the “write cache” to write-through. In the newest interface : And the creation succeeded. ps. this was an old issue, […]
