p.s.: Here the configuration of file "virtual_machine" name = "Name" builder = "generic" memory = 500 disk = ["format=raw,vdev=xvda1,backendtype=tap,target=/home/xen/disco.img"] vif = ["script=vif-route"] kernel = "/home/xen/kernel/vmlinuz-3.2.0-31-generic" ramdisk = "/home/xen/kernel/initrd.img-3.2.0-31-generic" extra = "root=/dev/xvda1 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. I could workaround that... I had to switch to this one: Code: extra = 'xennet.rx_copy, xencons=tty' ...

I've tried this config and ip is written to xenstore: /local/domain/0/backend/vif/6/0/ip = "" (n0,r6) >> If this is not a (known) bug or a general issue, I will provide some >> If this is not a (known) bug or a general issue, I will provide some logs (xen-hotplug.log or verbose vif-route etc). forgets to do this, so it always tries to use eth0, which obviously fails if you are using another interface.

Now in your domUs the /etc/network/interfaces has to look like this (staying with Code: auto eth0 iface eth0 inet static address # domU IP netmask # netmask to It's not worth it, so even if you're using vif-route successfully now, I can just recommend to stop using it.

The domUs get a "vif"-line like this: Code: vif = [ 'mac=AA:BB:CC:DD:EE:FF,ip=' ] Please note that it is best to define a MAC address here, one way of doing so would

Could you please tell me where the parsing code for the ip= parameter in xl.cfg is located so I could insert a printf or something like that for debugging? xinSun verified that when netfront type (does not use qemu-dm -net params) is used, networking works correctly. Then I delete the vif line in VM's configure file and recreate it again, this time vm is running normally. The vif-route systems could not reach the vif-bridged' systems due to, i suspect different gateways.

There's no difference. Shall I open a bug report or did some of you > already open one? It turns out to be rather simple once you know it, but a few changes have to be made to the system(s). xc: debug: hypercall buffer: total allocations:571 total releases:571 xc: debug: hypercall buffer: current allocations:0 maximum allocations:3 xc: debug: hypercall buffer: cache current size:3 xc: debug: hypercall buffer: cache hits:552 misses:3 toobig:16

I fixed it in my post. Contact Gossamer Threads Web Applications & Managed Hosting Powered by Gossamer Threads Inc. I am new to cloudmin and xen and it's been several days now trying to solve this damn thing! ip should be parsed and written to xenstore -- do you see it there (in the backend dir)?

Adding an ip address to the interface solved the problem. I need to use the routing setup, but for some weird reason it's impossible to get the vif interfaces created. Both servers have as OS Ubuntu and Xen version 4.6 (same configuration, network is routed). Can someone PLEASE-PLEASE get me out of my misery with this error?

This could be circumvented by modifying the initrd appropriately instead. If I migrate the VM with the following parameter: vif = [] it works. Once I remove the "vif=" line from my domU config, everything works ...
