I have installed Nova on Ubuntu 10.10 from ppa:nova-core/release.When launching an instance, I get the instances shutdown:

RESERVATION r-ca0tvrrq proj default INSTANCE i-00000011 ami-00000002 172.16.0.4 172.16.0.4 shutdown key01 (proj, ubuntu) 0 m1.medium 2011-07-21T04:21:26Z nova

I dont really know then. Its neigther a reason nor error, just fact :) (in libvirt.log) Check size of kernel/ramdisk/disk.img files in /var/lib/nova/instances/instance-0000001c/ if you know their real sizes(it`s fine if there is no ramdisk for example, but bad if disk or kernel has zero size or not the same size they should be - a few Mb for kernel and a few Gb for disk, the last dependds on your image). Or just terminate instance and remove _base dir completely(it will recreate). I suppose that if you create(upload&register) another image - will work fine. Smth strange is that(or any) 0 bytes file in _base dir, though it may not concern your image for current instance.

FUI, from first log error I can say that some image(disk.img or other) for VM eigther not fully transfered to nova-compute, or other bug with image-store service. You can just somehow repeat image creation(i.e bundle&upload&register to you storage-service) or if you want try to download you image bundle manualy.

Hi just try - go to the node named "ubuntu"(where nova-compute service) and look into /var/lib/nova/instances There must be non empty _base and dir with your instance name - see console.log, if it is empty see /var/log/libvirt/qemu/instance ...your_Instance_Number.log than you`ll find some reason ;) otherwise you may post some errors from there

On node named "Ubuntu", I run an instance named "i-0000001c".there are an _base dir that is not empty.

$ sudo ls -ls /var/lib/nova/instances/_base/ total 4308 4308 -rw-r--r-- 1 nova nogroup 4407632 2011-07-22 09:59 00000001 0 -rw-r--r-- 1 libvirt-qemu kvm 0 2011-07-22 09:59 00000002

the file: /var/lib/nova/instances/instance-0000001c/console.log is empty.And I find some reason into /var/log/libvirt/qemu/instance-0000001c.log :

I have tried again with ttylinux in link : http://smoser.brickies.net/ubuntu/ttylinux-uec/ (http://smoser.brickies.net/ubuntu/tty...) . And The instance is the running state . Then I tried with ubuntu 10.10 server i 386 on link : http://uec-images.ubuntu.com/releases/10.10/release/ (http://uec-images.ubuntu.com/releases...) with instance type m1.tiny ,It 's running . But I always fail when working with other types.And Have the same above error in the nova-compute.log What 's the problem in here ? Thanks for any help .

I have solved the problem because my physical machine is not enough resources. I created a new intances type and all is ok. Thanks!
