Ok, I think the problem is your KVM version. You probably need
to make the /etc/libvirt/qemu.conf changes I mentioned, to get
it to work.

New subject: [libvirt] the guest killed itself
yeh,it's working !
I can see that the VM already running and never kill itself now.
I appreciate your help very much.
but I meet another problem after I upgrade the libvirt version from 0.8.3 to
0.9.0.
I find that if I use "virt-viewer -c
qemu+ssh://192.168.7.126/systemvt_d_ubuntu",
the machine shows a message that "Unable to connect to libvirt with URL
qemu+ssh://192.168.7.126/system ".
I can't connect the VM running on another machine.
I only can use "virt-viewer -c qemu:///system vt_d_ubuntu" to connect the VM
running at local machine.
when the libvirt version is 0.8.3 , I can use "virt-viewer -c qemu+ssh://
192.168.7.126/system vt_d_ubuntu"to connect the VM running on the another
machine successfully.
It makes me confused.
I try to find a solution to solve the problem but failed.
Do you know some reasons may result it ? thanks.
best regards,
qinguan

This is ssh'ing as an unprivileged user, and so it likely doesn't have
permission for the socket. You can try 'qemu+ssh://root@192.168.7.126/system'
instead

Actually, the machine running VM only has one user : root.
I login the machine and run ssh both with the root permission.
And I also have a try by using "virt-viewer -c qemu+ssh://
root(a)192.168.7.126/system vt_c_ubuntu"
It still shows the same message .

New subject: [libvirt] the guest killed itself
If I use "kvm ubuntu.img -vnc :1" , I can use vncviewer and input the "
192.168.7.126:1" entering the VM successfully.
Is there any log file about libvirt that may show some clue?

qinguan

sorry ,I misunderstand your meaning.
I try with 'virsh -c qemu+ssh://root@192.168.7.126/system' as follows:
root@Optiplex-780:/var/log/apache2# virsh -c qemu+ssh://192.168.7.126/system
root(a)192.168.7.126's password:
error：server closed connection:
error：连接到管理程序失败(failed to connect to the monitor?)
root@Optiplex-780:/var/log/apache2#
