Re: Kernel 3.9 - can't boot qemu with accel=kvm _and_ networking enabled

[Vlad <vovan@vovan.nl>]

Paolo,

The full command line is:
qemu-system-x86_64 -machine accel=kvm -m 1024m  \
 -net tap -net nic \
 -drive file=/dev/zpool/testsrv,index=0,cache=writethrough \
 -k en-us \
 -no-kvm-irqchip \
 -vga cirrus

I've tried any combinations of "-net" options, but the result is always
the same. I think this somehow related to
http://article.gmane.org/gmane.comp.emulators.kvm.devel/109461, as
setting "emulate_invalid_guest_state=0" solves the problem However, I'm
not aware of any consequences of this change.

Regards,
Vlad.
