hi all, i''d really like to trace through xc_linux_save() in xfrd (to gain insight into how you transfer pages into dom0), but when it''s under control of gdb *and* there''s a breakpoint set in xc_linux_save, the domain save fails (most of the time): jake % /usr/sbin/xm save ttylinux yyy Error: errors: save failed and by "most of the time" i mean i''ve seen it work a few times, but it usually fails. without the breakpoint, xfrd can be under gdb and the save succeedes. is this approach even supported? i''d prefer to use a debugger to step through the code; printfs are SO crude ;). if you need trace or log output, just let me know. thanks in advance, -A. -- Aaron Marks Distributed Systems Lab University of Pennsylvania www.cis.upenn.edu/~ajmarks "Strange women lying in ponds distributing swords is no basis for a system of government." _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
