From 0ff26a3225d69ffec76fe5aca8296852fa951204 Mon Sep 17 00:00:00 2001 From: Anthony PERARD Date: Tue, 11 May 2021 10:28:07 +0100 Subject: [PATCH] libxl: Assert qmp_ev's state in qmp_ev_qemu_compare_version We are supposed to read the version information only when qmp_ev is in state "Connected" (that correspond to state==qmp_state_connected), assert it so that the function isn't used too early.
