This help to avoid guest creation error when a downstream project is also updating the iptables at guest creation time. The error seen is this one: libxl: error: libxl_exec.c:118:libxl_report_child_exitstatus: /etc/xen/scripts/vif-bridge online [-1] exited with error status 4 Apparently, exit status 4 could be a try again error. Signed-off-by: Anthony PERARD <anthony.perard@xxxxxxxxxx> --- This error is seen while using OpenStack with nova-network service running (instead of Neutron). OpenStack is updating the iptables with iptables-save and iptables-restore. The status 4 error also happend at guest shutdown time (with vif-bridge offline ...) and it appear to happen more often, but that not an issue since the guest is been destroy.
