Hi list,
I was just testing some old builds and managed to freeze the guest I was
testing on... Totally repeatable.
Running the same binary on a kernel not running in KVM does not cause
the lockup.
Guest:
# uname -a
Linux virtual.nagafix.co.uk 2.6.30.4 #4 SMP Fri Jul 31 07:40:18 BST 2009
x86_64 QEMU Virtual CPU version 0.10.50 GenuineIntel GNU/Linux
Host:
# uname -r
2.6.29.4
# qemu --version
QEMU PC emulator version 0.10.50 (qemu-kvm-devel-87), Copyright (c)
2003-2008 Fabrice Bellard
Here is how you can reproduce it (in the guest):
wget http://uml.nagafix.co.uk/uml/kernels/kernel32-2.6.16.62.bz2
bunzip2 kernel32-2.6.16.62.bz2
./kernel32-2.6.16.62
Sorry, I haven't had time to look into what is causing this system freeze.
Cheers
Antoine
