I found a bug in lxc_driver.c. Could you try the following patch? diff --git a/src/lxc/lxc_driver.c b/src/lxc/lxc_driver.c index 2851a2a..018e9f8 100644 --- a/src/lxc/lxc_driver.c +++ b/src/lxc/lxc_driver.c @@ -883,6 +883,9 @@ static int lxcSetupInterfaces(virConnectPtr conn,             goto error_exit;         } +        /* Prevent auto-assigned names re-used */ +        parentVeth[0] = '\0'; +        containerVeth[0] = '\0';     }     rc = 0; --- > > > > Regards, > > Srikanth. > > -- > libvir-list mailing list > libvir-list(a)redhat.com > https://www.redhat.com/mailman/listinfo/libvir-list >
