(just > testing now). Use of the live flag to gate the flush/sync calls is not a good idea. We can 'live save' to disc (checkpointing) and we can 'non-live migrate' via a socket. So the live flag is not really an indicator of what the file descriptor maps to (file vs. socket). Best to unconditionally try the flush/sync and ignore errors. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
