Dear all:
Afer run the command 'qemu-kvm -hda /root/free.img -m 512 -usbdevice
tablet -vga qxl -spice port=5930,disable-ticketing' , and the VM starts
natrually. Then I run the command 'virsh list' , it shows as follows:
[root@localhost ~]# virsh list
Id Name State
----------------------------------
[root@localhost ~]#
there is no VM running! I am puzzled , can someone help me?
Yours Sinerely!

Running a VM directly via qemu-kvm makes the VM invisible to libvirt,
unless you first run 'virsh qemu-attach'. There are certain
restrictions for this to work, such as having a socket-based monitor on
the guest. 'virsh list' can only list VMs known to libvirt.

New subject: [libvirt-users] 答复: 'virsh list' issue
Thanks for your help.
However, how can I make the VM visible to libvirt of that kind.? Even with
third party tools?
Yours Sinerely!

Hi,
well, you are not using the libvirt api to create the vm :) You need to
use something like "virt-install" and then start the vm via "virsh
start".
Afaik "virsh list" only shows machines which are using libvirt.
Kind regards,
Felix Blanke

Yes & no. This depends on driver being used. There are several drivers
that doesn't need to connect to the libvirt daemon. Virsh is then used
to communicate with hypervisor directly - e.g. xenapi does this. And it
is hypervisor who keeps track of domains. That means, if one would
somehow create a domain behind libvirt back, virsh list would show it
anyway. NB this is not recommended.
However, qemu is not such hypervisor therefore your answer is correct. I
just wanted to clarify :)
