2008-11-12Fix brown-paper-bag bugs from live-migration patch (Charles Duffy)aliguori1-0/+1
In TCP migration, prevent an endless loop trying to retrieve error status. In exec migration, set the close pointer in the FdMigrationState structure. Color me embarrassed.

2008-11-11Reintroduce migrate-to-exec: support (Charles Duffy)aliguori1-0/+141
KVM's live migration support included support for exec: URLs, allowing system state to be written or received via an arbitrary popen()ed subprocess. This provides a convenient way to pipe state through a compression algorithm or an arbitrary network transport on its way to its destination, and a convenient way to write state to disk; libvirt's qemu driver currently uses migration to exec: targets for this latter purpose. This version of the patch refactors now-common code from migrate-tcp.c into migrate.c.
