The issue is that dom0 is trying to copy data to a domU-provided buffer, but the buffer details appear bogus. Netback returns a -1 error to netfront, which then prints out its error message. It's not immediately obvious whether the bug is in netfront or netback. If it's an issue that crops up with many guests then I suppose it's more likely a netback issue, which is a pain. Do domUs lose their connection at the same time, or is it random individual domUs losing their connection from time to time? -- Keir > Since this is a running production system i can schedule a reboot for a > new kernel, but this takes some time. _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
