I am seeing a problem when live migrating a guest under unstable when I
have xm configured to XenAPI.
If my xm-config.xml file has the XenAPI stuff commented out - live
migrate (xm migrate --live <domid> <dest IP>) seems to be working in my
test environment.
However, if I enable it - I get failures when migrating the same guest
(see dump from xend.log below.) They obviously go down quite different
code paths in these two cases.
Being somewhat new to the xm, and xenapi control stacks - I was hoping
someone might point me in the right direction to track down what might
be happening here...
Any help is appreciated.
