After installing and configuring the qemu-guest-agent in the guest - https://wiki.libvirt.org/page/Qemu_guest_agent it should give you the IP with the domifaddr --source flag:
# virsh domifaddr avocado-vt-vm1 --source agent Name MAC address Protocol Address ------------------------------------------------------------------------------- lo 00:00:00:00:00:00 ipv4 127.0.0.1/8 - - ipv6 ::1/128 enc1 52:54:00:22:36:1b N/A N/A On Wed, Sep 15, 2021 at 5:50 PM Charles Polisher <c...@chasmo.org> wrote: > On 9/9/21 11:11, Kaushal Shriyan wrote: > > > I have assigned static IP for all the below KVM Guest VM's.
