If you can create a copy on write blockdevice with linux, you can use it with xen. So with current xen stable, it might work with LVM. Otherwise, from the xen roadmap at http://www.cl.cam.ac.uk/Research/SRG/netos/xen/roadmap.html: - Better copy-on-write filesystem support. Although Linux's LVM snapshot capability can be used to provide CoW filesystem support it doesn't scale well. A custom approach should do rather better. /Ernst _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users |
