1. I run a user domain like this:

[root@kvm1 ~]# qemu-system-x86_64 -enable-kvm -m 1G -smp 4 /images/test1.img

WARNING: Image format was not specified for '/images/test1.img' and probing guessed raw.

         Automatically detecting the format is dangerous for raw images, write operations on block 0 will be restricted.

         Specify the 'raw' format explicitly to remove the restrictions.

2. Then, I install and using my user domain.

3. Then, I login to libvirtd on my hosts,but can not get the user domain using list command.
