From: Daniel P. Berrangé Date: Mon, 7 Feb 2022 12:10:28 +0000 (+0000) Subject: qemu: fix formatting of pflash readonly attribute X-Git-Tag: v8.1.0-rc1~150 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3ef9b51b10e52886e8fe8d75e36d0714957616b7;p=thirdparty%2Flibvirt.git qemu: fix formatting of pflash readonly attribute When the had an explicit readonly='no' attribute we accidentally still marked the plfash as readonly due to the bad conversion from virTristateBool to bool. This was missed because the test cases run with no capabilities set and thus are validated the -drive approach for pflash configuration, not the -blockdev approach. This affected the following config: /var/lib/libvirt/qemu/nvram/test-bios.fd for the sake of completeness, we also add a test XML config with no readonly attribute at all, to demonstrate that the default for pflash is intended to be r/w.
