[SOLVED] VGA v.s. SERIAL differences between

[fireon]

Hello,

on the thread Cloudinit with Proxmox i configured the first time a VM with serial port instead of the typical vga. So what i'am interested for is, what are the advantages of serial port? For me they were the JS/xterm feature that it is easy to copy/past things in, and you can enter den konsole directly in pvecli like xen.
There are some more advantages, or some disadvantages?

Thanks

I'd also throw in
- better scriptability in comparison to the GUI
- better security if you block ANY incoming traffic to the VM and use only serial to configure
- depends heavily on the OS, but all unix-like OSes should not have a problem with that
and most importantly:
- feeling like a real pro
- AND feeling really old

Thanks a lot

another advantage is easier debugging - you can turn on a lot of verbosity in lots of places and dump the serial console output to a file for grepping, even for early stuff like Grub or the initramfs which don't/can't log to log files.
