commit faddd16e367530fe4de5480610f69d8ceb6011d8 Author: Juergen Gross <jgross@xxxxxxxx> AuthorDate: Thu Nov 4 17:11:21 2021 +0100 Commit: Andrew Cooper <andrew.cooper3@xxxxxxxxxx> CommitDate: Thu Nov 4 18:43:20 2021 +0000 tools: disable building qemu-trad per default Using qemu-traditional as device model is deprecated for some time now. So change the default for building it to "disable". This will affect ioemu-stubdom, too, as there is a direct dependency between the two. Today it is possible to use a PVH/HVM Linux-based stubdom as device model. Additionally using ioemu-stubdom isn't really helping for security, as it requires to run a very old and potentially buggy qemu version in a PV domain. This is adding probably more security problems than it is removing by using a stubdom.
