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 2011/5/5 Daniel P.

Hi, Thanks a lot for your reply sincerely!
some version infoemation: root@shahe26:~# libvirtd --version libvirtd (libvirt) 0.9.0 root@shahe26:~# kvm --version QEMU PC emulator version 0.12.5 (qemu-kvm-0.12.5), Copyright (c) 2003-2008 Fabrice Bellard root@shahe26:~#
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.
If you have oldish versions, you might need to edit
/etc/libvirt/qemu.conf
and set 'clear_emulator_capabilities = 0', and user=0, group=0 to make QEMU run as root with full privileges.
