# Currently there is a bug (fixed in virt-manager-1.3.2-1.el7) so you will need to edit the xml to remove the channel definition:

NAME=new_test
virsh dumpxml ${NAME} > ${NAME}.xml
virsh undefine ${NAME}
vi ${NAME}.xml ; virsh define ${NAME}.xml ; virsh start ${NAME}

openssl genrsa -out server.key 4096
openssl req -new -key server.key -out server.csr
openssl x509 -req -days 365 -in server.csr -signkey server.key -out server.crt

Now copy to the right config folder:

cp server.crt /<configuration folder>/ssl.crt
cp server.key /<configuration folder>/ssl.key
