virsh capabilities does not include qemu or kvm

[shafnamol N]

Hi,

I am new  to Libvirt and Qemu.I have installed Libvirt 7.1.0 and qemu-kvm 4.2.0.

I configured and built libvirt based on instructions from

https://libvirt.org/compiling.html.

But when i tried to create a VM using virsh it shows the following error:

# virsh create /home/abc.xml
error: Failed to create domain from /home/abc.xml
error: invalid argument: could not find capabilities for arch=x86_64 domaintype=kvm

When i check the hypervisor capabilities ,it doest show qemu or kvm in guest domain type.

# virsh capabilities

      <emulator>/usr/local/libexec/libvirt_lxc</emulator>
      <domain type='lxc'/>
    </arch>
  </guest>

</capabilities>

I have restarted libvirt to get the qemu support,but  it is not shown in capabilities list.What will be the problem?

Thanks for the help in advance....
