Hi, I have permission issues with ovirt node and iSCSi. 2013-02-20 11:20:47.854+0000: 15899: error : virNetClientProgramDispatchError:174 : internal error process exited while connecting to monitor: qemu-kvm: -drive file=/rhev/data-center/20ca8725-0221-4227-b87a-5e6d71ab6fe3/ce0168c1-e69f-479e-a591-daca0a8ee7db/images/ebb3b49c-717d-4ae5-8ddb-4d25a367126c/60ddc3a1-7855-4c0a-a5a6-7169bc29db3a,if=none,id=drive-virtio-disk0,format=qcow2,serial=ebb3b49c-717d-4ae5-8ddb-4d25a367126c,cache=none,werror=stop,rerror=stop,aio=native: could not open disk image /rhev/data-center/20ca8725-0221-4227-b87a-5e6d71ab6fe3/ce0168c1-e69f-479e-a591-daca0a8ee7db/images/ebb3b49c-717d-4ae5-8ddb-4d25a367126c/60ddc3a1-7855-4c0a-a5a6-7169bc29db3a: Permission denied I tried chown 36:36 /rhev/data-center/20ca8725-0221-4227-b87a-5e6d71ab6fe3/ce0168c1-e69f-479e-a591-daca0a8ee7db/images/ebb3b49c-717d-4ae5-8ddb-4d25a367126c/60ddc3a1-7855-4c0a-a5a6-7169bc29db3a which leads to /dev/ce0168c1-e69f-479e-a591-daca0a8ee7db/60ddc3a1-7855-4c0a-a5a6-7169bc29db3a which leads to /dev/dm-13 I tried all of them to chmod 36:36, but this does not help. But if I change to vdsm user (su - vdsm -s /bin/bash I can read from it) After chmoding this file it started to work (VM started) /rhev/data-center/20ca8725-0221-4227-b87a-5e6d71ab6fe3/ce0168c1-e69f-479e-a591-daca0a8ee7db/images/ebb3b49c-717d-4ae5-8ddb-4d25a367126c/2ea15f6b-8029-474f-90c9-e693e4c10a67 Creating new hard drives still doesn work. I have node version 2.6.0-20130212.fc18.
