| Dear all, I am using libvirt in conjunction with LXC. In accordance with http://libvirt.org/formatdomain.html#elementsHostDevCaps I pass an InfiniBand adapter through to the guest container. However, within the container the access permissions are not the same. Within the host they are like this: crw-rw-rw- 1 root root 10, 56 20. Jun 09:40 rdma_cm crw-rw-rw- 1 root root 231, 224 20. Jun 09:41 ucm0 crw-rw-rw- 1 root root 231, 0 20. Jun 09:41 umad0 crw-rw-rw- 1 root root 231, 1 20. Jun 09:41 umad1 crw-rw-rw- 1 root root 231, 192 20. Jun 09:41 uverbs0 Within the guest, only root may read or write from/to the device: crw------- 1 root root 10, 56 20. Jun 09:40 rdma_cm crw------- 1 root root 231, 224 20. Jun 09:41 ucm0 crw------- 1 root root 231, 0 20. Jun 09:41 umad0 crw------- 1 root root 231, 1 20. Jun 09:41 umad1 crw------- 1 root root 231, 192 20. Jun 09:41 uverbs0 Do you have any ideas how I can tell lxc via libvirt to change the permissions in such a way that they correspond to those on the host system? Best regards, Simon |
