If it hasn't, we need to fix xend to write the passwd before starting qemu, and/or qemu needs to treat failure of the xs_read() as an indication that there is no authentication. What do you think is the problem? Is the passwd getting written after qemu is started and hence racing the xs_read() in xenstored? We don't want to work around this with a timeouts. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
