Re: [Xen-users] forcing disk in read only also if mounted

well, if you read my first post, you'll see that setup is working right now with /dev/Xen2Volume/domU-kernel-needed mounted in ro.

i want it in ro within domU and rw in dom0.
the reasons are explained in my first post...

Sorry, I missed that on my first reading.

I'm pretty sure that isn't possible. The kernel assumes that for regular partition types (i.e. not networked) that it is the only device writing to the partition. If another device is writing to the partition, then the kernel will make incorrect assumptions.

If you don't want communication to/from dom0 from any of the domUs required by NFS, you could make a domU NFS server that would host the share and give it a virtual nic for every bridge that you want synced.
