[Xen-devel] pv_ops 2.6.32.12: network problem: Attempting to checksum a non-TCP/UDP packet, dropping a protocol 1 packet
I am using a pv_ops dom0 kernel 2.6.32.12 with xen 4.0.0-rc8. My domU''s use 2.6.31-14-server ubuntu. When I try to ping another computer on the network from the domU I still received this error: Attempting to checksum a non-TCP/UDP packet, dropping a protocol 1 packet I thought this error was fixed somewhere around 2.6.32.10 but apparently it is still in 2.6.32.12. How do I get around this problem? -Gerry _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Please try again (it will be 2.6.32.13) and tell me how it goes.

Is this problem (and fix) also related to the issue described here? http://wiki.xensource.com/xenwiki/XenFaq#head-4ce9767df34fe1c9cf4f85f7e07cb10110eae9b7 I posted about a checksum problem not to long ago in this xen-users thread http://lists.xensource.com/archives/html/xen-users/2010-05/msg00456.html TIA for any info.

There was an user complaining about this bug on ##xen (CC) and he said he was using the latest xen/master.. he grabbed the patch from xen/stable-2.6.32.x and applied it to his 2.6.31 tree and it started to work OK after that. -- Pasi _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
