Recently when confronted with what turned out to be a networking issue that my Proxmox Virtual Environment cluster was having, the only way to interact with the hosts was through the management console.
Of course, as a result of a networking problem on something like a 5 node Proxmox plus Ceph cluster during a network problem, the host gets pretty chatty to its logs. And much of that gets displayed on the console you are trying to use.
Proxmox being built on Debian Linux means that dmesg is the utility to control the "kernel ring buffer" (basically whatever the kernel has to say) and the default is to display it all on the console.
If you log in on the console and need to get stuff done without being bombarded by kernel messages, you can run `dmesg -D` to disable the printing of messages to the console. When you want them back, `dmesg -E` enables them again.
