virsh and bash_complete

[Mohsen Pahlevanzadeh <mohsen@xxxxxxxxxxxxxxxxx>]

Dear All,

I downloaded the attachment file and activate for bash_complete, It can give you the following output:
# virsh net-
net-autostart    net-dhcp-leases  net-info         net-undefine
net-create       net-dumpxml      net-list         net-update
net-define       net-edit         net-name         net-uuid
net-destroy      net-event        net-start       


--Best regards
Mohsen
