When a domain is resumed after aborted save (e.g., because of insufficient space on a device where the domain is being saved), xm console cannot send/read any data. The reason is that the event channel used by xenconsole stays unbound. This patch modifies xenconsoled to check current status of open event channels and rebind them if necessary. close() + open() is the sledge hammer approach (will work though). Just unbind(local_port) should be enough. cheers, Gerd _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
