Hi, Both the virt-manager and my xend service are on the same server. When I first start virt-manager, and connected to my xend service, all my non-started vms are listed. But if I start any of them, either from the UI or from the terminal, the vm disappear immediately, and it will remain disappear as long as the vm is running. Even restart virt-manager will not help. The manager worked very well previously, so I think upgrading my system may break something. But I need some help troubleshooting this. -- Regards, David Shen http://about.me/davidshen https://twitter.com/#!/davidshen84
