No Internet through sys-net and sys-firewall in qubes 4.0

[Taehwan Kim]

Hi all.

I need your help.

I just did cleaned up dnf package and rm -rf /var/log in fedora-30 template which sys-net and sys-firewall using for template last night.

But my qubes not connecting internet through sys-firewall and tried netvm with sys-net in other appVM but no internet.

Only in sys-net internet is working. So I checked..

In sys-net

ip addr | grep -i cast

2: wls7: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000 <--- this is wifi connection
3: ens6: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000 <--- this is wired connection
4: vif16.0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 32 <-- I think this is sys-firewall connected to sys-net

in sys-firewall

ip addr | grep -i cast

2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
3: vif18.0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 32

I have no idea how to find a problem for this. If sys-firewall has some problem, internet must be working when I use sys-net for net vm for appVM..

But I switched to sys-net as netvm for appvm, Internet is not working.

So I think I have a problem with sys-net maybe..

Can you help me? :(

Yes, that vif interface should be UP on both. Check sudo journalctl in
sys-net to see if any related errors are logged. Might try creating a
new sys-net from scratch to see if that helps (make a new AppVM with
"provides network" checked, set to HVM, attach your NIC(s)).
