X-Git-Tag: v5.10.0-rc1~48
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=07675b0100da4b26a84bc53a7480b4293eb52543;p=thirdparty%2Flibvirt.git

qemu: domain: Store virStorageSources representing pflash backing

To allow converting the pflash drives to blockdev we will need a
virStorageSource to allow using our helpers. Temporarily prior to
coverting loader data to a virStorageSoruce add private data which will
house this.
