Patch series available in this git branch: https://xenbits.xen.org/git-http/people/aperard/ovmf.git br.platform-xen-pvh-v2 Hi, I've started to create a Xen specific platform, in OvmfPkg/XenOvmf.dsc with the goal to make it work on both Xen HVM and Xen PVH. The first few patches only create the platform and duplicate some code from OvmfPkg and the later patches makes OVMF boot in a Xen PVH guest and can boot a Linux guest. After this patch series, I'd like to wait a bit before removing Xen support from the OvmfPkg*.dsc, to allow time to switch to the new Xen only platform, maybe 1 year. Question: Should we start moving these to a different *Pkg? Like it's done for ArmPkg and ArmVirtPkg? Maybe XenPkg. To build and boot: To build, simply run OvmfPkg/build.sh -p OvmfPkg/XenOvmf.dsc Then use OVMF.fd as a kernel of a pvh guest config file (with xl/libxl).
