Sure. (I don't know exactly what you need to know, but I'll try.) To make the domUs boot and shutdown correctly, I modified the init / shutdown scripts somewhat to be able to cope with two root filesystems: The domU which has only the base filesystem needs to mount that read/write, so we can install updated software, perform fsck, etc. All the other domUs needs to mount their "changes" filesystem read/write, perform fsck on it at startup, etc. but mount the "base" filesystem read-only. That's about it, I think? _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users |
