[Xen-devel] [PATCH V3 4/5] tools: support system supplied ovmf binary

[Wei Liu <wei.liu2@xxxxxxxxxx>]

From: Ian Campbell <ian.campbell@xxxxxxxxxx>

Debian Jessie at least contains an ovmf package that includes
/usr/share/ovmf/OVMF.fd. It's also possible that user may want to supply
his/her own ovmf binary.
