  1. High Bandwidth (Download) Causes VM to Lockup

    Hi there, I'm having an issue on my hosts (2) wherein whenever I download large files/ISO's or run Speedtests etc and it consumes most of the available bandwidth for my ISP downlink (1Gbps), it seems to tank the Windows VM I am using at the time to download. I am connecting to the Windows VM's...
  2. [SOLVED] SSH 'refused connect' | PVE

    Hi there, I may have broken SSH on my PVE host by doing `systemctl stop sshd` a while back in the shell and not the web GUI - ever since, I've not been able to connect to the host over SSH. It's showing as running, and even accepts incoming SSH connections, however all connection attempts are...
  3. RAW disks -> qcow2 | LVM disks

    Hi there, I have just finished setting up my second homelab host and come to the horrible realisation that my 2 x 2TB and 4TB disks are all LVM and have running VM's on.

  7. Hostname Change - PVECluster not starting - Corrupt DB?

    Hi all, I've attempted to change the hostname of my server and it seems to have sledgehammered my server. Hopefully there is an easier way to change this in the future. My process of changing the hostname was, alter /etc/hosts and /etc/hostname and also the /etc/postfix/main.cf hostname...

    Hi all, I have a question regarding the 'Snapshot' option when it comes to backups. I am looking for a quicker option for less downtime and have been using the Snapshot backup option.
