No Network Using Qemu-kvm-ev-2.3.0-31.el7.16.1
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

Ok, problem is not with qemu-kvm-ev-2.3.0-31.el7.16.1 package, it is with systemd-networkd. I have installed openvswitch and all works ok. Then, my question, is why is it not possible to use systemd-networkd for configure virtual switches to use them with KVM guests in CentOS 7 (using for other things, they seem work ok)??
In Ubuntu, Arch and Debian there is no problem with systemd-networkd configured bridges for KVM guests.
Any idea why ??
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.
