# failed to create VM on 2nd compute node

Hi,

I have two compute nodes; first one (say CN_01) is on the same node which is also the cloud-controller node, while the 2nd node (say CN_02) is a dedicated compute node.

CN_01 has following processes; 1.) nova_apir 2.) nova-network 3.) nova-compute 4.) nova-scheduler 5.) nova-objectstore 6.) glance-registry 7.) glance-api

I have not made any setting changes to "/etc/glance/glance-api.conf" ... so everything is running on defaults.

I have registered an image (the standard ttylinux image); output of euca-describe-images is: $euca-describe-images IMAGE ami-00000003 mybucket/ttylinux-uec-amd64-12.1_2.6.35-22_1.img.manifest.xml available public x86_64 machine aki-00000001 ari-00000002 IMAGE ari-00000002 mybucket/ttylinux-uec-amd64-12.1_2.6.35-22_1-initrd.manifest.xml available public x86_64 ramdisk IMAGE aki-00000001 mybucket/ttylinux-uec-amd64-12.1_2.6.35-22_1-vmlinuz.manifest.xml available public x86_64 kernel When I create an instance of this image on CN_01, everything works fine. However, when I create an instance of the same image on CN_02 it fails. I am not sure if it is a bug or wrong configuration; I am attaching the nova-compute.log. Please let me know if the cause of problem is obvious.
