Per RHEL documentation it is possible to edit the grub2 prior to launching the installer, in case special options are needed ahead of time. The same holds true for CentOS.

When I point virt-install to a local ISO image, by the time I can launch a remote virt-manager instance, the installer proceeded past the option to set grub2 options (there is a several second delay).

Is there any way to pass grub2 options to the installer using virt-install?


This is actually possible, however I needed to have my remote virt-manager instance up and already connected to the host.

As soon as the virt-install command is issued at the host, I see the new guest instance appear in virt-manager, and was able to connect to it in time to edit configuration options for the installer.
