Hello List, I'm ironing out details to upgrade a few systems to CentOS7. My servers have BMC with Serial over LAN support. In C5 and C6, I determined how to have BIOS/POST, kernel, and serial console access. I'm reading up on the method to accomplish the pieces with C7. Presently SoL output works, so I see BIOS/POST messages and the GRUB boot list. My changes to enable serial

Is there a way to get GRUB2 and the kernel to run a "serial" console under KVM?

When I try the same with a CentOS 7 VM, it doesn't work. If I set it to ttyS0, I just
