While investigating a bug reported on Red Hat Bugzilla
https://bugzilla.redhat.com/show_bug.cgi?id=1166461
I discovered the following
xl migrate --debug domid localhost does indeed fail for Xen 4.4 pv (the
bug report is for Xen 4.3 hvm ) when xl migrate domid localhost works.
There are actually two issues here
* the segfault in libxl-save-helper --restore-domain (as reported in the
bug above) occurs if the guest memory is 1024M (on my 4G box) and is
presumably because the allocated memory eventually runs out
* the segfault doesn't occur if the guest memory is 128M, but the
migration still fails. The first attached file contains the log from a run
with xl -v migrate --debug domid localhost (with mfn and duplicated lines
stripped out to make the size manageable).
I then tried xen 4.5-rc1 to see if the bug was fixed and found that xl
migrate doesn't work for me at all - see the second attached file for the
output of xl -v migrate domid localhost .
