if the hypervisor is kvm, you can check the qemu log is there any exceptions,
like /var/log/libvirt/qemu/instance-00000111.log
if Xen used, log file is at /var/log/xen/qemu-*.log

Thank you for answer.
My image is OK，after vm created, I can login my instance.
I have many virtual machines running (10+), generally after a few days(1+) a
virtual machine automatic shutoff occurs.Yesterday, the situation becomes
worse, suddenly all the virtual machines all shut off.I did not see anything
unusual logs in nova (did not see the warning/error)
I use devstack , and nova version is(last commit):
* commit 3d418dcf860894523eff62a8338d09d58e994b0e
Merge: e76848a 8b4896b
Author: Jenkins <jenk...@review.openstack.org>
Date: Sun Nov 4 00:49:54 2012 +0000
Merge "handles empty dhcp_domain with hostname in metadata" into
stable/folsom
And I do not upgrade nova.

hi pengyuwei,
I guess may be your image of VMs is broken，so your VMs will shutoff after being
created,
just a guess.
good luck!

My virtual machine created, often in the absence of intervention into the
stopped state:
pyw@ven-1:~/devstack$ virsh list --all

query the nova the database, you can see:
vm_state: stopped
