Running xenstore-* when xenstored is not started, it will hang and cannot accept any signal, e.g. SIGINT. I seems that the process is blocked at accessing '/proc/xen/xenbus'. # mount -t xenfs xenfs /proc/xen/ # xenstore-ls call trace: do_ls() -> xs_directory() -> xs_talkv() -> xs_write_all() -> write() BLOCK is no problem but why process cannot accept signal, Any opinion? If start xenstored in other console, xenstore-ls executes and then receive the signal, seems the signal is pended... -- Regards Yu Zhiguo _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
