Yes, I am using Opennebula to manage my Xen cluster. Is there any networking issue when using Xen with opennebula? Can you please tell me a little more about ARPing .

Thanks for the response.

Regards,

Prakhar

Hi Prakhar,

These problems are generally caused due to ARP propagation issues.
I would suggest attempting to reach the machine with ARPing from another host on the LAN.

Also by any chance are you using OpenNebula?

Hi,
I have two debian machines (debian squeeze) with xen 4.0 installed using debian repository packages. The VMs created on machine1 are accessible from the local network and internet is accessible within the VM. However, when I try to ping the VMs on the machine2 from any host other than the machine itself(Dom0), i get a DESTINATION HOST NOT REACHABLE error.If I try to ping the VM from the DomO, it works fine.

The configuration file for machine2 VM is as follows:

name = 'vm2'
memory = '256'
vcpus = '1'
kernel = '/home/cloud/kernel/xen/2/vmlinuz-2.6.27.21-0.1-xen'
ramdisk = '/home/cloud/kernel/xen/2/initrd-2.6.27.21-0.1-xen'
root = '/dev/xvda'
extra = 'xencons=tty'

disk = [
   'file:/srv/cloud/one/var//145/images/disk.0,xvda,w',
   'file:/srv/cloud/one/var//145/images/disk.1,xvdd,w',
   'file:/srv/cloud/one/var//145/images/disk.2,xvdc,r',

]
vif = [
   ' mac=02:00:c0:a8:91:fd,ip=192.168.145.253,bridge=eth0',
]

I hope someone can advice what could be the possible issue.

Regards,
Prakhar
