Re: [CentOS-virt] No network using qemu-kvm-ev-2.3.0-31.el7.16.1
Nop. Problem was with systemd-networkd. Using openvswitch of ifcfg-XXX config files, all works ok without problems.

Re: [CentOS-virt] No network using qemu-kvm-ev-2.3.0-31.el7.16.1
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. -- Greetings, C. L.

[CentOS-virt] 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 -- Greetings, C. L.
