Re: [Xen-users] tcp checksum errors across dom0-domu bridge

Now the dom0 and domU can ping each other, and even establish a tcp connection, but dom0->domU tcp packets always seem to have a failing checksum. (see tcpdump trace of a telnet session below)

Are you getting 'insufficient headroom' message in the domU? (see
dmesg).

If so, upgrade to a newer 3.0.0 build number - the RPMs on the web site
should already be updated.

No, dmesg looks clean in both dom0 and domU. Sames results for xen-3.0-testing-20051206 and xen-3.0-testing-20051227. (I only upgraded the hypervisor to 20051227.)
