@twaapo @ddelnano Hi ! I think the problem is here: installation:map[method:network repository:] You need to have some value for the var "repository" After some digging in internet, XAPI code (because why not), I found the solution in an old commit in the XO repo: https://github.com/vatesfr/xen-orchestra/commit/07bf93e022a0026cacf28bf8797646361f7ea4a6 I think the var need to be set to "pxe" (i'm doing some more digging) 0 julien-f committed to vatesfr/xen-orchestra Add PXE installation method for HVM templates. (fix #436)
