Okay I just rebooted.
Now the guest os takes forever to startup with the same behaviour as before.
I have no traffic on my tap device. The only trafic on tap device is from
the guest os and for now there is not much.
And here is the output of dmesg
apic write: bad size=1 fee00030
Ignoring de-assert INIT to vcpu 0
kvm: emulating exchange as write
And the cpu usage it to 100% by system not user when locking up and goes to
user when running. It runs for 2-3 sec then hang and goes to 100% cpu usage
by system for 10 sec or more.
Im getting the same behaviour with my firewall (nat) disabled.
I just removed the tap device from the startup parameters and voila the
guest boots with no problems.
I reinsert my tap parameter and the guest os dont boot as before still with
nat and firewall disabled, tap device is up with an ip address.
Im still trying to do anything to solve this issue :-), feel free to give
some suggestions :).
