Problems with libvirt for MIPS

Hello. It's my first time here, so I'm so sorry if I make mistakes with how I'm sending or posting this. I wanted to ask about some problems I've found with other people, working with libvirt. We wanted to create a new virtual machine under MIPS architecture, using Qemu and libvirt. We are able to create the machine, and it boots, but never gets an IP. I'll leave the commands we've used, for the case someone knows what could be wrong. Qemu commands: libvirt+ 41690 25.0 11.5 837532 147992 ? Sl 14:15 0:04 /usr/bin/qemu-system-mips -name guest=MIPS_32,debug-threads=on -S -object secret,id=masterKey0,format=raw,file=/var/lib/libvirt/qemu/domain-137-MIPS_32/master-key.aes -machine malta,accel=tcg,usb=off,dump-guest-core=off -m 256 -realtime mlock=off -smp 1,sockets=1,cores=1,threads=1 -uuid eef94af7-4f20-4a00-9ae9-9b4133c1783b -display none -no-user-config -nodefaults -chardev socket,id=charmonitor,path=/var/lib/libvirt/qemu/domain-137-MIPS_32/monitor.sock,server,nowait -mon chardev=charmonitor,id=monitor,mode=control -rtc base=utc -no-shutdown -boot strict=on -kernel ~/vmlinux -append root=/dev/hda -device piix3-usb-uhci,id=usb,bus=pci,addr=0x2 -drive file=~/rootfs.ext2,format=raw,if=none,id=drive-ide0-0-0 -device ide-hd,bus=ide.0,unit=0,drive=drive-ide0-0-0,id=ide0-0-0,bootindex=1 -netdev tap,fd=26,id=hostnet0 -device pcnet,netdev=hostnet0,id=net0,mac=52:54:00:09:a4:38,bus=pci,addr=0x1 -device virtio-balloon-pci,id=balloon0,bus=pci,addr=0x3 -device pcnet -netdev user,id=net1 -msg timestamp=on Thanks anyway!!!
