If I've read the patches right, I believe Yogi is relying upon control.parallel; these changes are needed to ensure that the unattended_install test invoked in parallel doesn't clobber itself. Yogi hit all of the major issues: 1) tftp code uses the same path and filename for each guest; Yogi switched that to include a per-guest path so we can have multipl kernel/initrd pairs in flight at the same time 2) only one service side listening server and no way agreeing upon a port number; Yogi moved the listen to the guest, and now the host pokes at the pre-defined port in each guest to see if it has completed. -- Ryan Harper Software Engineer; Linux Technology Center IBM Corp., Austin, Tx ryanh@xxxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
