All Ubuntu guest don't work

All Ubuntu guest don't work

[satimis]

Hi folks,

host - debian 5.0
guests - Debian/Windows/Ubuntu


Recently I found all Ubuntu guests can't boot hanging on.
....
kernel_thread_helper+0x7/0x10
- end -

I even can't start on recovery mode.  Other guests are working properly.


Just tried installing a new Ubuntu 10.04 guest without success.  The  
CD started to boot but hanging on the screen finally;
......
? kernel_init+0x67/0x10
? kernel_thread_helper+0x7/0x10
Clocksource tsc unstable (delta = 2081173336636 na)
- end -

Please help.  TIA

What version of qemu/kvm in your host?

That's extremely old.  You should update to a newer version.

Hi Anthony,

I found my problem was caused by running the new kernel of the host  
(Debian 5.0 32 bit), causing all Ubuntu guests unable to boot.  The  
kernel has been upgraded recently.

I booted the old kernal

$ uname -a
Linux vm0.debian50 2.6.26-1-686 #1 SMP Fri Mar 13 18:08:45 UTC 2009  
i686 GNU/Linux


All Ubuntu guests revived (all 32 bit).


The new kernel is;
Debian GNU/Linux, kernel 2.6.26-2-686


Ubuntu 10.04 (32 bit) can be installed without problem.

Anything can I try before upgrade qemu/KVM ?  Thanks

Hi Anthony,

Further to my late posting.

Something I can't explain.  Just rebooted to the new kernel.  This  
time all Ubuntu guests worked including the newly installed Ubuntu  
10.04 desktop.  Debian and Windows guest also worked.

Funny !!!
