Free Video :<\/strong>Hyper-V: Change Resolution in CentOS (Red Hat) VM
\n<\/strong><\/div>\n

One of the common problems that you hit when installing the GUI in a CentOS (Red Hat) Hyper-V guest is changing the default screen resolution – 1152×864. Most of the published solutions are for Ubuntu Hyper-V guests, and if you’ve come here, you are probably aware that they are not applicable for CentOS and Red Hat VMs.<\/p>\n

In this short video, we demonstrate how to change the screen resolution in CentOS and Red Hat Hyper-V Virtual Machines using the grubby tool. The instructions are valid for both version 6 and version 7 of the OS. For your convenience, we provide the commands that we are using in the video:
\n# Use “grubby” to update all current and future kernels passing the video argument
\n# for the Microsoft Hyper-V Synthetic Video Frame Buffer driver
\ngrubby –update-kernel=ALL –args=”video=hyperv_fb:1024×768<\/span><\/strong>”<\/p>\n

# A reboot is required to apply the changes:
\nreboot<\/p>\n
