What are the relevant entries in |
| 20 |
|
| 21 |
/etc/exports on the host |
| 22 |
/etc/fstab on the guest |
| 23 |
|

root on one is not different to root on another; root is root. Well |
| 25 |
actually it's EUID=0 is EUID=0 but you get the idea. |

|
| 27 |
Your problem is one of |
| 28 |
root_squash active on the host |
| 29 |
mounted ro on the guest |
| 30 |
exported ro on the host |
