Connecting to VM serial port remotely

[ideasman69]

Hi all,
Long time lurker, first time poster. I've configured a VM and have a virtual serial port attached. Usually I just login to the proxmox interface and utilise the xterm console which works a treat.

But I'm curious if it's possible to connect to the virtual serial port over IP via Putty somehow? I'd like to leave the session running and log everything coming through to a file to help troubleshoot a problem.

Thanks!

an easier way is to add a chardev device that just logs console/serial output to file:

--args '"-chardev file,id=char0,mux=on,path=/tmp/serial.'$vmid'.log,signal=off -serial chardev:char0"' \

That works perfectly! Thanks

I can't use xterm in the proxmox ui anymore which is fine, tail -f on the logfile works nicely. Question is - does this argument string remove the need for the virtual serial port in the hardware configuration? Or does it work with it?

Also - how does one remove the arg string? I've tried using

qm set 101 --args ''

to remove it, but it remains - albeit empty

normally you would do it with "qm set --delete"

you still need virtual serial port, in fact we use two - second one for actual console.
