Has anyone gotten networking in an HVM domain to work with the emulated NE2000 rather than the emulated PCnet? I have Linux running in an HVM domain just fine with pcnet. If I change the config file to say ne2000=1, the tun0, vif0.1, and xenbr0 devices get created in dom0, the kernel in the HVM domain brings up eth0 OK (NE2000 support is built into the kernel), but I can''t get dom0 to talk with the HVM domain. ping in either direction (dom0 to domU and domU to dom0) says "Destination Host Unreachable". dmesg in domU shows no errors. Any ideas? Steve D. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Would be nice to have fixed. Ian _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

I''m looking into the performance of HVM domains and notices that networking with PCnet takes a big hit. I was curious how the performance of the NE2000 emulation compares with that of PCnet.
