[libvirt] virsh can list ("virsh list" is empty) Guest domains created by "xl create DomU"

[Volo M.]

Hi,

We use Centos 7 Xen hypervisor, start VMs with xl toolkit (libxl), but we
can't list with "virsh list" command DomUs created with "xl create ..."
command.
Can anybody, please, explain why this happens? Why does it work like this?
It worked before with "libvirt+xm" toolkits, but xm toolkit was deprecated
for latest Xen sortware on Centos 7.
Can this be fixed ever?
Thank you.


Example:

[root at c7xen2 ~]# xl create /onapp/config/w62tp7db1txk12

...

[root at c7xen2 ~]# xl list

Name                                        ID   Mem VCPUs State Time(s)

Domain-0                                     0   400     2     r-----

w62tp7db1txk12                               1   512     1     -b----

[root at c7xen2 ~]# virsh list
