I am running Oracle Linux 6.5 with RedHat compatible kernel (no UEK) inside Hyper-V, only text mode (no X server). I am using the following parameters in /boot/grub.conf
SYSFONT=latarcyrheb-sun16 video=hyperv_fb:1920x1080 nomodeset
But the text is too small. I am trying to increase the font size but nothing seems to work. It seems this is likely due to the hyper-v framebuffer. How can I change the font size when using the hyper-v framebuffer?
