Hi
trying to get hands on ovirt virtualization.
built a test environment on vmware workstation:
- 2 VMs running centos7 as ovirt Hosts
- 1 VM running centos 7 as ovirt-manager
on ovirt Hosts:
[root@ovirt-node1 ~]# rpm -q cockpit-ovirt-dashboard qemu-kvm-ev libvirt virt-install
bridge-utils vdsm
cockpit-ovirt-dashboard-0.13.10-1.el7.noarch
qemu-kvm-ev-2.12.0-44.1.el7_8.1.x86_64
libvirt-4.5.0-36.el7_9.5.x86_64
virt-install-1.5.0-7.el7.noarch
bridge-utils-1.5-9.el7.x86_64
vdsm-4.30.46-1.el7.x86_64
on ovirt-manager:
[oVirt shell (connected)]# info
backend version: 4.3.10
sdk version : 4.3.4
cli version : 3.6.9.2
python version : 2.7.5.final.0
entry point : https://ovirt-manager.home.lab/ovirt-engine/api
I created two ovirt VMs, running ubuntu16, on the same VM Networks "vmnet-02"
Both VMs' traffic cannot go outside hosts (i.e they can reach each others only if they
run on the same host)
need help fix this please!
