I haven't looked more into this but noticed an e1000 patch from
Anthony Perard which may improve the Solaris experience:
emulated netcards don't work with recent sunos kernel
You received this bug notification because you are a member of qemu-
devel-ml, which is subscribed to QEMU.
Status in QEMU: New
i'm using qemu-kvm backend in version: # qemu-kvm -version
QEMU PC emulator version 0.12.5 (qemu-kvm-0.12.5), Copyright (c) 2003-2008
and there are just *not working any of model=$type with combinations of recent
sunos (solaris, openindiana, opensolaris, ..) ..
you can download for testing purposes iso from here:
http://dlc-origin.openindiana.org/isos/147/ or from here:
http://genunix.org/distributions/indiana/ << osol and oi are also bubuntu-like
*live cds, so no need to bother with installing
behaviour is as follows:
e1000 - receiving doesn't work, transmitting works .. dladm (tool for handle
ethers) shows that is all ok, correct mode is loaded up, it just seems like
this driver works at 100% but ..
rtl8169|pcnet - works in 10Mbit mode with several other issues like high cpu
utilization and so .. dladm is unable to recognize options for this kind of -nic
others - just don't work
.. i experienced this issue several times in past .. woraround was, that
rtl8169 worked so-so .. with recent sunos kernel it doesn't.
it's easy to reproduce, this is why i'm not putting here more then launching
script for my virtual machine:
# cat openindiana.sh
qemu-kvm -hda /home/kvm/openindiana/openindiana.img -m 2048 -localtime -cdrom
/home/kvm/+images/oi-dev-147-x86.iso -boot d \
-vga std -vnc :9 -k en-us -monitor
-net nic,model=e1000,vlan=1 -net tap,ifname=oi0,script=no,vlan=1 &
ip l set oi0 up;
ip a a 192.168.99.9/24 dev oi0;
