Created attachment 434458 [details] emerge --info xen-tools Xen-Tools 4.6.1-r1 build fails while building OVMF due to image size exceeding 1 MB limit. Happens with any of gcc 4.8.5, 4.9.4 and 5.3.0. Both hardened and vanilla exhibit it. Caused by attempting to build OVMF in RELEASE mode, which attempts to generate 1 MB image by default. It seems that patched by Gentoo, OVMF does not fit.

I don't use xen but use ovmf with qemu with image size 2MB. I think it should not be a problem to increase the image size to 2 MB.
Cannot reproduce with xen 4.10.1, please report back if it's still an issue. We had an ovmf update before, so maybe the size was increased with that sync.
