Cannot connect to serial0 / xterm.js

[Razva]

Hey,

I can't connect to serial0 via xterm.js and I have no idea what I'm doing wrong. Yes, serial0 is already added and video output is set. Can you please give me a hint?

Here's /etc/pve/qemu-server/100.conf contents:

agent: enabled=1,fstrim_cloned_disks=1
boot: c
bootdisk: scsi0
cipassword: some_password

serial0: socket
vga: serial0

Here's the guest's /etc/default/grub contents:

GRUB_DEFAULT=0
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT=""
GRUB_CMDLINE_LINUX="console=tty0 console=ttyS0,115200 earlyprintk=ttyS0,115200 consoleblank=0"
GRUB_TERMINAL="console serial"
GRUB_SERIAL_COMMAND="serial --speed=115200"

Unfortunately I'm getting this:

TASK ERROR: command '/usr/bin/termproxy 5901 --path /vms/100 --perm VM.Console -- /usr/sbin/qm terminal 100 -escape 0 -iface serial0' failed: exit code 1

And in the browser:

Connection failed (Error 500: Timeout while waiting for port '5901' to get ready!)

Any hints are highly appreciated! Thank you

Inside my Debian VM, I use:
GRUB_CMDLINE_LINUX_DEFAULT="console=tty0 console=ttyS0 consoleblank=0" GRUB_TERMINAL=serial and ran update-grub.
And the VM configuration uses (same as yours):
serial0: socket vga: serial0
And the xterm.js console viewer (PVE 7.0-11) works fine: it displays boot messages and console login works.
Maybe remove the 115200 bitrate settings? Maybe its a network issue; have you tried other viewers? Anything in the Proxmox Syslog?
