Alpine 3.18 in aarch64 QEMU/KVM VM, has ethernet interface, but no communication results?
Alpine 3.18 in aarch64 QEMU/KVM VM, has ethernet interface, but no
communication results? The eth0 interface exists, I can ping it if I
assign a static IP address via /etc/network/interfaces. And the route
table has a default gateway as expected. But no communication results?
On the same aarch64 system, VMs running say Debian 11, Debian 12, and
Ubuntu 22.04 Jammy Jelly fish work as expected, in reference to network
communication. So I believe I have QEM/KVM installed correctly, I happen
to be using a bridge interface to the physical NIC on the SBC that is
aarch64 based. The SBC is an IndieDroid Nova.
Any help is greatly appreciated. Detail information...

What ip address has br0?
Can you ping 192.168.1.2 from the host?
Would it be possibele that there are other hosts that has the address
192.168.1.211 (eg ip address conflict)?
Could it be other machines connected to br0 that has mac
address='52:54:00:62:b1:4b'?
Can you share the dumpxml from one of the working debian or ubuntu
machines?

Thanks for the reply, I did some more testing, and it appears the
direct-bridge configuration is now broken. Something has broken the br0
configuration as it is now, it was working, otherwise the Debian 11 and
12 NetInst installs would have failed.
When I happen to install alpine in a VM, and it could not find the DHCP
server, so I assigned a static IP, and it still was not communicating.
Recreated a typical NAT based virtual network under QEMU/KVM, it works,
all VMs, including the alpine VM, which communicates as expected. So I
am going to have to back track to find what has broken the br0 bridge on
my SBC device. There have been several updates, etc. between the Debian
VMs built and the Alpine VM. Really odd.

Just to close out this thread...
I rebuilt the system, re-installed QEMU/KVM, recreated the bridge
configuration. Both Debian 11/12 based VMs work as expected, and now
Alpine works as expected in reference to the odd connectivity issue as
noted below. As some point the bridge configuration was broken in
between the time I created the Debian 11/12 VMs and then the Alpine VM.
There was other work done on the host system, system updates, etc.
Docker was installed at one point. I am now retracing the steps to see
if I can pin point the specific step that broke the bridge configuration.
To all those that replied, etc. Thanks. Notice to see, or read rather,
there is active support on a mailing list these days!
