Summary: Destination host of migration crashes
Product: Xen
Version: unstable
Platform: All
OS/Version: All
Status: NEW
Severity: normal
Priority: P2
Component: Hypervisor
AssignedTo: xen-bugs@xxxxxxxxxxxxxxxxxxx
ReportedBy: dbarrera@xxxxxxxxxx
CC: hohnbaum@xxxxxxxxxx
I am testing the migration feature. When I attempted to migrate to a host, the
host to which I am migrating the domain crashed. It looks like the receiving
host is running out of memory; however, dom0 should not crash.
