Hi, on my Debian Lenny (freshly upgraded from Etch), I have a weird issue that didn't happen on Etch. (Linux yggdrasil 2.6.26-1-xen-amd64 #1 SMP Sat Jan 10 20:39:26 UTC 2009 x86_64 GNU/Linux) After figuring out why I couldn't boot into the new kernel after upgrade (Lenny uses Xen 3.2, but my old Xen 3.0 was retained ... so removing it and installing the 3.2 version fixed that issue), I needed to adjust the kernel and ramdisk parameters in the .cfg file of the domUs. In addition, I had to change this line in /etc/xen/xend-config.sxp: Code: (network-script network-route) to Code: (network-script 'network-route netdev=eth0') Now Code: /etc/init.d/xend start works as expected. Only one huge issue left. Whenever I try to create a domU from any of the config files, it fails with the following error: Code: Error: Device 0 (vif) could not be connected. /etc/xen/scripts/vif-route failed; error detected. The gist of my xend configuration file is this: Code: (xend-address localhost) (network-script 'network-route netdev=eth0') (vif-script vif-route) (dom0-min-mem 96) (dom0-cpus 0) Only the "network-script" line had to be changed after the upgrade, everything else is as it used to be. I need to use the routing setup, but for some weird reason it's impossible to get the vif interfaces created. They also do not appear inside the output from ifconfig. Any ideas?
