Hallo, at first, sorry for my bad english. I have a big problem. I have xen 3.0.1 running. I have 4 domU. One domU is hosting a dns-server. All runns fine. Yesterday i have updated to 3.0.2. Sorce from the tar file. Build a new kernel and reboot the system. It''s running. But i have one problem. The dns resolving runns not fine. Is there any changes for the dns between 3.0.1 and 3.0.2? Can you help me please? A network with no dns ist a dad network. :( -- cu Roland Kruggel mailto: rk.liste@bbf7.de System: Intel 3.2Ghz, Debian etch, 2.6.15, KDE 3.4 _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Or you could try a newer tarball of 3.0.2-testing; on Wed Apr 5 09:39:13 2006 changeset 1003eb92cfdd was commited with description "Fix checksum-offload problems introduced in c/s 9514, due to data_validated flag not being properly specified on the device channel." I guess this change is included in the April 6 tarball.
