I used to concatenate filesystem images using dd skip=xx but never found a way to notify the domU of a successful change. add in the fact, that large numbers of [ phy:... or, even worse file: ] disk definitions tend to be unreliable and it would be REALLY great to get the feature back. maybe we can start a little rally to make someone from -devel aware this is a NEEDED feature? rgds, florian -- 'Sie brauchen sich um Ihre Zukunft keine Gedanken zu machen' _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users |
