[virt-tools-list] errors when running virt-manager on Ubuntu 14.04 server

[Liu, Xuan (UMKC-Student)]

Hello,


I have installed KVM on Ubuntu 14.04 server and installed virt-manager. I was able to start virt-manager through ssh from my Macbook to create VMs.


I just ran into this issue when I reboot my system today, and apparently I cannot open virt-manager when I ran ssh from my macbook pro. I didn't make any change except for reconfigure the IP address on the bridge that connects the VMs, and then rebooted the server.


I checked the log file under ~/.virt-manager/, and I saw this error.


[Tue, 04 Nov 2014 05:46:35 virt-manager 32765] DEBUG (error:80) dialog message: Error polling connection 'qemu:///system': internal error: client socket is closed : Error polling connection 'qemu:///system': internal error: client socket is closed

Could you please give me any hints what might be the reason?


Thanks,
