I am using Ubuntu 12.04 as controller node and CentOS 6.6 as compute node (Icehouse). When I try to create an instance, it directly goes into the ERROR state without even scheduling. The scheduler log shows the following results.

I have deleted all the instances but I am still unable to launch any. However, my disk size is less. Is that a problem?

[root@compute ~]# df -Th

Try cirros as m1.tiny. m1.small won't work for sure.

Tried that as well, didn't work either. Instance instantly goes into ERROR state.

OK, now I am able to launch the first instance using Ubuntu qcow2 image but I get an ERROR when I try to launch another one. If I use CirrOS, I can launch upto 3 or 4 instances after which I get ERROR while launching instances. My dashboard limit summary shows a lot of free space. What could the problem be?
