Hello, 

I am trying to PXE boot a laptop terminal via a wired ethernet connection to a 9front qemu guest, but 
I can't get past "No boot filename received" on the terminal. 

I thought it was a problem of the terminal and the qemu guest not seeing each other's network, 
however after the terminal boots from its local disk, I can telnet from the terminal 
to the guest via a port I've forwarded in qemu, and I can ping the terminal from the 
qemu guest. So at least it seems possible for the two to reach each other.

Maybe I need to configure a bridge as suggested in IRC, but perhaps my config is wrong though 
so I would appreciate any help. 

Here's the config I have:


cpu% cat /lib/ndb/local

[....]

# the qemu guest
sys=gene ether=525400123456 authdom=qemu auth=10.0.2.15 ip=10.0.2.15 tftp=10.0.2.15

ipnet=qemu ip=10.0.2.0 ipmask=255.255.255.0
	ipgw=10.0.2.2
	auth=10.0.2.15
	authdom=qemu
	fs=10.0.2.15
	cpu=10.0.2.15
	dns=10.0.2.15
	dnsdomain=qemu
	tftp=10.0.2.15

# the laptop terminal
sys=ursula dom=ursula.qemu ether=0016d3c16297 ip=10.42.0.156 bootf=/386/9bootpxe 


cpu% cat /cfg/gene/cpurc 
ip/ipconfig
ip/dhcpd
ip/tftpd


cpu% cat /cfg/pxe/0016d3c16297 
bootfile=/386/9pc
bootargs=tls
nobootprompt=tls
auth=10.42.0.1
fs=10.42.0.1
cpu=10.42.0.1
mouseport=ps2intellimouse
monitor=vesa
vgasize=1024x768x16
*acpi=1
user=glenda



And the qemu startup:


qemu-system-x86_64 -enable-kvm -cpu host -m 2G \
-net nic,model=virtio,macaddr=52:54:00:12:34:56 \
-net user,\
hostfwd=tcp::17010-:17010,\
hostfwd=tcp::17019-:17019,\
hostfwd=tcp::17020-:17020,\
hostfwd=tcp::12567-:567,\
hostfwd=udp::69-:69,\
hostfwd=udp::564-:564,\
hostfwd=udp::567-:567, \
-device virtio-scsi-pci,id=scsi \
-drive if=none,id=vd0,file=9front.qcow2.img \
-device scsi-hd,drive=vd0 \



Just out of curiosity, I've wondered why the bootf and the bootfile are different (and there is no 9pc in /386/ 
on the qemu guest). Is 9pc somewhere else at first?

thanks, George

I couldn't get the network 100% working with qemu user networking, 
so I did end up setting up a bridge and got the terminal to boot. 

One note if it helps other beginners in the future, I couldn't figure out where  
the /386/9pc bootfile was on my cpu server until helpful folks in IRC clued me 
that I needed to cross-compile for 386 (on my 64 bit qemu cpu server), see 
https://fqa.9front.org/fqa5.html.

I use tls boot on my mac.  You need to copy the kernel somewhere and have the usual plan9.ini file as initrd, and give a 512-byte file as nvram.

qemu-system-x86_64 \
	-machine accel=hvf \
	-cpu host \
	-smp sockets=1,cores=2,threads=1 \
	-m 1024 \
	-nographic \
	-drive file=/opt/9/nvram,if=virtio,index=0,media=disk,format=raw \
	-nic user,mac=99:66:11:22:33:44,model=virtio-net-pci,ipv6=off,hostname=apple,domainname=9core,hostfwd=tcp:127.0.0.1:17019-:17019 \
	-kernel /opt/9/9pc64 \
	-initrd /opt/9/plan9.ini
