Also remove the Wants=3D dependency since do not want to start any service.= We cannot know which one libvirt-guests is configured, so we'd have to start a= ll the daemons which would break if unused colliding services are not masked (libvirtd.service in the modular case and all the modular daemon ser= vice units in the monolithic scenario). Fortunately we can assume that the syst= em is configured properly to start services/sockets that are of interest to the u= ser. That also works with the setup described in https://libvirt.org/daemons.htm= l . To make it even more robust we add the daemon service into the machine units created for individual domains as it was missing there. https://bugzilla.redhat.com/show_bug.cgi?id=3D1868537 Signed-off-by: Martin Kletzander --- src/util/virsystemd.c | 4 ++++ tools/libvirt-guests.service.in | 12 +++++++++++- 2 files changed, 15 insertions(+), 1 deletion(-) diff --git a/src/util/virsystemd.c b/src/util/virsystemd.c index a86d4c6bb905..2d9711ad41b6 100644 --- a/src/util/virsystemd.c +++ b/src/util/virsystemd.c @@ -441,7 +441,9 @@ int virSystemdCreateMachine(const char *name, nicindexes, nnicindexes, s= izeof(int)); gprops =3D g_variant_new_parsed("[('Slice', <%s>)," " ('After', <['libvirtd.service']>)," + " ('After', <['virt%sd.service']>)," " ('Before', <['virt-guest-shutdown.= target']>)]", + drivername, slicename); message =3D g_variant_new("(s@ayssus@ai@a(sv))", name, @@ -489,7 +491,9 @@ int virSystemdCreateMachine(const char *name, uuid, 16, sizeof(unsigned char)); gprops =3D g_variant_new_parsed("[('Slice', <%s>)," " ('After', <['libvirtd.service']>)," + " ('After', <['virt%sd.service']>)," " ('Before', <['virt-guest-shutdown.= target']>)]", + drivername, slicename); message =3D g_variant_new("(s@ayssus@a(sv))", name, diff --git a/tools/libvirt-guests.service.in b/tools/libvirt-guests.service= .in index 1a9b233e1177..3cf647619612 100644 --- a/tools/libvirt-guests.service.in +++ b/tools/libvirt-guests.service.in @@ -1,10 +1,20 @@ [Unit] Description=3DSuspend/Resume Running libvirt Guests -Wants=3Dlibvirtd.service Requires=3Dvirt-guest-shutdown.target After=3Dnetwork.target After=3Dtime-sync.target +After=3Dlibvirtd.socket +After=3Dvirtqemud.socket +After=3Dvirtlxcd.socket +After=3Dvirtvboxd.socket +After=3Dvirtvzd.socket +After=3Dvirtxend.socket After=3Dlibvirtd.service +After=3Dvirtqemud.service +After=3Dvirtlxcd.service +After=3Dvirtvboxd.service +After=3Dvirtvzd.service +After=3Dvirtxend.service After=3Dvirt-guest-shutdown.target Documentation=3Dman:libvirt-guests(8) Documentation=3Dhttps://libvirt.org --=20 2.35.1
