The serial console does not respond, or provide any output, for virtual machines based on Oracle Linux 7 that are of domain type HVM or PVHVM.
Workaround: Configure the GRUB bootloader for the virtual machine as follows:
Add the following lines to the
/etc/default/grub
file:GRUB_CMDLINE_LINUX=" console=ttyS0 console=tty0 crashkernel=auto \ rd.lvm.lv=ol/root rd.lvm.lv=ol/swap rhgb quiet" GRUB_TERMINAL="serial console" GRUB_SERIAL_COMMAND="serial --unit=0"
Run the following command to update the
grub.cfg
file:grub2-mkconfig -o /boot/grub2/grub.cfg
Restart the virtual machine.
Note that the preceding lines provide suggested configuration. You
should consult the GNU GRUB manual for descriptions of each line
and additional configuration options to suit your business needs.
The GNU GRUB manual is available from the following directory on
the virtual machine: usr/share/doc/
.
Additionally, you should refer to the About the GRUB2
Boot Loader section of the Oracle Linux
Administrator's Guide for more information.
Use the following keys to navigate the boot menu: v for down-arrow and ^ for up-arrow.
