virsh is a tool to manage virsh guest domains and the command “virsh console [domain id/name]” can be use to connect the virtual serial console for the guest. But sometimes the connection with the serial consoleĀ hangs or stucked at the “escape character ^] ” and not bringing you to the guest login after pressing “Enter” , it looks something like this:
tux@ubuntuserver1:~$ virsh console 11
Connected to domain eve-ng
Escape character is ^]
In order to exit, need to use Escape character depending on type of keyboard. Typically, for English keybord “Ctrl+]” will work.
Here are few stepsĀ you can try to fix this:
1. Edit/update the /etc/default/grub configuration (some distribution maybe different). Tested working in Ubuntu.
From:
GRUB_TERMINAL=console
GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash vga=788″
To:
GRUB_CMDLINE_LINUX_DEFAULT=”console=tty0 console=ttyS0″
GRUB_TERMINAL=serial
GRUB_SERIAL_COMMAND=”serial –unit=0 –speed=115200 –word=8 –parity=no –stop=1″
2. Update the config and reboot
#update-grub
Sample output:
root@eve-ng:~# update-grub

done
3.Ā Ā Enable and start serial getty
# systemctl enable serial-getty@ttyS0.service
# systemctl start serial-getty@ttyS0.service
4. Reboot
#reboot
Verify:
tux@ubuntuserver1:~$ virsh list

tux@labucs1:~$ virsh console 4

Eve-NG (default root password is ‘eve’)

Looks good, if you have other access options to the guest e.g. ssh. If not, one can sit and cry
systemctl enable serial-getty@ttyS0.service may (that’s the case for me on debian mv & kvm) be sufficient, without grub stuff
