0.11.0-rc1 bugs

0.11.0-rc1 bugs

[Alexander Graf]

Hi list,

while trying out 0.11.0-rc1 I stumbled across several bugs and wanted  
to share them with you, so whoever feels bored knows what's left to do  
out there :-)

Unless I'm completely stupid, all of the following cases worked with  
0.10.6 on the same machine (kernel, kvm-kmod).
Linux with IDE as guest works great.

My kernel configuration:

   OpenSUSE 11.1 with 2.6.27 kernel and kvm-kmod-2.6.30.1.

Bugs:

   - Xen doesn't boot (fails with "..MP-BIOS bug: 8254 timer not  
connected to IO-APIC")

   - Mac OS X boots for a bit, then qemu-kvm exit(1)'s with  
"hpet_disable_pit: kvm does not support pit_state2!"
     It even breaks with -no-hpet! -no-kvm-pit works around it.

   - extboot doesn't get installed

   - extboot doesn't work (-drive ...,if=virtio,boot=on fails)


If you find additional problems in 0.11.0-rc1 or found that I only did  
something wrong, please reply to this thread.

You may want to try the latest stable-0.11 branch which is close to
0.11.0-rc2. Should resolve at least some of your issues.

I've seen such issue with SLES10 2.6.16 and "notsc" kernel parameter.
Didn't dig deeper though.

The last two are solved in stable-0.11.

Right, I should try that too.

-no-kvm-pit makes it work here.

That is based on my own stupidity, forcing hpet_init to happen even  
with !no_hpet.

Ok :-).
