First, dmesg shows that driver for network card is loaded, you could
check with "ip link show" to see is there enp2s0 available.

Second, check with "ip addr show" does your enp2s0 gets an IP address...

Alexandre,

what is in your /etc/network/interfaces file ? or do you use systemd-networkd ?
do you have dmesg log from this machine ?
have you tried to do "modprobe ne2k-pci" after machine boots?
what is "ip link show" output?

Thanks.

Network not detected

2020-03-05 Thread Alexandre Bencz 

Hi
I just installed Debian on a QEMU virtual machine, during the 
installation, the internet connection was detected and etc, but after 
starting the system, the connection does not exist


Ps: I'm using Windows

My QEMU command line is:
qemu-system-sparc64.exe -machine sun4u,accel=tcg,usb=off -m 2048 
-nographic -hda debian_sparc64.qcow2 -net nic,model=ne2k_pci -net 
user,hostfwd=tcp::-:22 -monitor telnet::4440,server,nowait -serial 
mon:telnet::,server,wait
