What is your exact QEMU command line?
Does ping 10.0.2.2 work? Is the interface up in the ifconfig output?
I'm currently more focused on sun4v emulation, so I'm not sure about
the ne2k status. My blog post from May 2012 [1] says it was not
working at that time, but it was before Mark improved the IOMMU
support. But virtio was definitely working in 2015. Please try
-net nic,model=virtio -net user
qemu boot parameters (modifying the "interrupts" property described in
[1] should not be necessary nowadays).
