qemu networking problem after system upgrade

Hi,

I am fairly new to qemu, I am using the following command to run my ubuntu VM:

qemu-system-x86_64 -enable-kvm -hda ubuntu_root.qcow2 -hdb ubuntu_home.qcow2 -m 1024 -smp 2 -nographic -monitor /dev/null -net user,hostfwd=tcp::5022-:22 -net nic

This command used to work perfectly a month ago approximately and I was able to have a network connection inside the guest without problem.
After a view system updates, I am now unable to have internet connection inside the vm. Nothing was changed apart from the package updates on the host. I can still connect through ssh using port 5022.

I checked pacman.log and I see the qemu was updated recently which could be what causes this problem. Is it a bug or do I have to change the above command?

Thank you

EDIT: Here is are the things I have tried inside the vm:

ping python.org

ping: unknown host python.org

So I tried downloading something instead of pinging:

wget 54.183.133.27

wget 54.183.133.27

So it seems network connection works. But why am I unable to resolve hostnames?
