@Jeremy Fanguède I see that during the xen build the version stable-4.13 is expected to be used:
https://gerrit.automotivelinux.org/gerrit/c/AGL/meta-agl/+/22200
meta-agl-bsp/virtualization-layer/recipes-extended/xen/xen_git.bbappend

FILESEXTRAPATHS_prepend := "${THISDIR}/files:"
XEN_REL = "4.13"
XEN_BRANCH = "stable"
SRCREV = "721f2c323ca55c77857c93e7275b4a93a0e15e1f"

but we faced with build error

ERROR: xen-4.13+gitAUTOINC+721f2c323c-r0 do_fetch: Fetcher failure: Unable to find revision 721f2c323ca55c77857c93e7275b4a93a0e15e1f in branch stable even from upstream

The the following correction helps:

XEN_BRANCH = "stable" -> XEN_BRANCH = "stable-4.13"

Did you have the similar issue or?

In theory the same Xen binary should also work on H3, but I could only test it on M3.

To enable it also on H3, a Xen specific device tree should also be created for H3.
