virt. machines hang on boot after upgrade to f14

[Michael Kürschner]

Hello,

 on weekend I upgrade my Fedora from version 13 to 14. Yesterday I try
boot my virtuell machines thats I have configured under fedora 13
virt-manager, but no machine boot, for example Fedora, Ubuntu and
Windows.

If start a virtual machine, I see the BIOS screen and than it switch
to a prompt. The cpu graph in virtmanager show a constant line by
round 30% but the harddisk io graph show nothing.

I try something: reinstall the virt packages, erase the libvirtd
configuration and create a new virtual machine, with different hd
options, virtio, ide, scsi. I disable selinux and reenable selinux
with wrote the selinux flags new on filesystem. If I create a new
machine, I see the boot screen from cd-image but if it switch to the
normal boot, it shows only the prompt.

What can I do to run machines under f14? Or which information can I
send to you to locate the problem. I'm desperate and have no idea.

My hardware are an AMD Phenom X2 (, with enable virtuallisation option
in BIOS) and under f13 the kvm machines run and run .....

Kind regards
Micha

Hello,

  I think it's same as in my bug:

    https://bugzilla.redhat.com/show_bug.cgi?id=649333

Try to use host kernel from koji.

I think another solution is to use non-PAE kernel in guest, but then you
will be limited to use < 4GB RAM.

Hello SAL,

 thanks for the link to bugzilla. It let me hope. I will test the
alternative kernel this evening.

And I see that I'm not alone with the problem :(

Hello,

 I have install the kernel-2.6.35.8-59.fc14.i686 package from koji
(http://koji.fedoraproject.org/koji/buildinfo?buildID=205096) and it
works fine. The virtual machine start and the CPU runs in normal
regions. I have test it with the old kernel and see that one core runs
in 100% if I start a virtual guest.

Thanks a lot for the hint.

regards,
Michael
