Subject: [PATCH] virt-install: Document Secure Boot setups
Provide ready to use recipes for explicitly enabling and
explicitly disabling Secure Boot, as well as a pointer to
the more extensive information found on the libvirt website.
Setting loader_secure=yes is only one part of a proper Secure
Boot setup, so stop documenting it in the section about manual
firmware selection to avoid confusion.

Specify that the virtual machine use the custom OVMF binary as boot firmware,
mapped as a virtual flash chip. In addition, request that libvirt instantiate
the VM-specific UEFI varstore from the custom "/.../OVMF_VARS.fd" varstore
template. This setup is not recommended, and should only be used if
- --boot uefi doesn't know about your UEFI binaries. If your UEFI firmware
- supports Secure boot feature you can enable it via loader_secure.
+ --boot uefi doesn't know about your UEFI binaries.
