Hi all,
To do some tests, I have installed a new CentOS7 host (fully patched) using qemu-kvm-ev-2.3.0-31.el7.16.1 instead of qemu-kvm's default package. And I have problems with network inside my guests.
All guests can ping to CentOS host but nothing more: can't resolv dns names, can access via tcp to other hosts, etc ... Using same config on other CentOS7 host, but using default qemu-kvm package instead of qemu-kvm-ev-2.3.0-31.el7.16.1, all works ok.
What am I doing wrong? Or is it a bug?
Thanks
Martinez, Any more config you have checked for DNS resolution related? You can ping to other host in the network right?

Hello, this could be issue with firewall or netfilter on bridge

Nop. Problem was with systemd-networkd. Using openvswitch of ifcfg-XXX config files, all works ok without problems.
