Forget to add... In my code, I use if ((shmid = shmget(shmkey,sizeof(mdc),IPC_CREAT | 0640)) == -1) err(1,"shmget"); to create a shared segment and if ((shmid = shmget(shmkey,sizeof(mdc),0)) == -1) err(1,"shmget"); to get an id for already created segment. Both are failing under non-root vimage jail, but it works under main host. At first I thought shared memory is not yet virtualized, but ipcs display existing segments in both root/main host and vnet jail.ipcrm, however, works only in non-jailed host... ipcrm: shmid(131072): : Function not implemented Regards, Milan _______________________________________________ freebsd-virtualization@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-virtualization To unsubscribe, send any mail to "freebsd-virtualization-unsubscr...@freebsd.org"
