Hi James Thanks for your reply when i am trying without vhost there is an error "Failed to connect socket: No such file or directory" since i used to specify socket path vhost.0 before i am new and i am not sure how to create socket manually by command FYI :- i have tried before running virsh command to enable VM it worked fine, that time my socket loaction was socket,id=charmonitor,path=/var/lib/libvirt/qemu/domain- 15-testsh2/monitor.sock i came to know that virsh command will not help in spdk nvme , so i am trying to enable VM by qemu command. Please let me know if there is an way to launch spdk nvme setup by virsh as well .
