Hello,
I just wanted to give kvm-tool a try and it unfortunately seems to be
stuck somewhere:
$ ./kvm run --disk linux-0.2.img --kernel
../../../linux-2.6/arch/x86/boot/bzImage
# kvm run -k ../../../linux-2.6/arch/x86/boot/bzImage -m 448 -c 4
Warning: Unable to open /dev/net/tun
PPrroobbiinngg EEDDDD ((eedddd==ooffff ttoo ddiissaabbllee))...... ookk
This is with kvm master at 6dfc8581f14d355a89e7edaf4394ee8c69177f1f
(cloned this evening).
Could anybody tell me what I did wrong ?
Thanks

Nothing. That looks like a bug. Could you try to do
kill -3 `pidof kvm`
on the host when the guest kernel hangs and post the output? Also, can
you post the output of
uname -a
on your host machine?
