Hi all£¬

    I try to use gdb to debug libvirt's source code, but when I tend to create a domain with xml, it shows "error: internal error Network 'default' is not active", so I use the net-related commands as below.

"

virsh # net-start default

error: Failed to start network default

error: Cannot open network interface control socket: Operation not permitted

"

Then I check my URI, which is "qemu:///session", because adding "sudo virsh". I try to change URI to "qemu:///system" by clicking "virsh # connect qemu:///system". The following logs shown below:

Could you please tell me the reason? 

Thanks a lot!
