Description of problem:

When installing fedora 9 64bit under KVM, the VM is created and the console
opens, and loads from the DVD, but at the boot: prompt the message "attempted
DOS system call" occurs.

If I select QEMU instead of KVM as the hypervisor, the installation does
continue past the boot: prompt.

Version-Release number of selected component (if applicable):

libvirt.x86_64                           0.4.3-1.fc10           installed
libvirt-python.x86_64                    0.4.3-1.fc10           installed
python-virtinst.noarch                   0.300.3-7.fc9          installed
virt-manager.x86_64                      0.5.4-4.fc9            installed

How reproducible:
100%

Steps to Reproduce:
1. create new VM
2. installation source /dev/sr0

Additional info:

N.B I had to install libvirt 0.4.3 from rawhide to work around problem
with

libvirtError: virDomainCreateLinux() failed internal error Timed out while
reading monitor startup output

This is a KVM bug when using the -drive parameter

The following two commands should be identical:

# qemu-kvm -cdrom /home/berrange/boot.iso -boot d -m 500

# qemu-kvm -drive
file=/home/berrange/boot.iso,if=ide,media=cdrom,index=2,boot=on -m 500

But the 2nd fails with 'Attempted DOS system call'. New libvirt uses the -drive
argument, hence why you see it the problem with newer libvirt.

Oh, don't forget to do 'service libvirtd restart' after installing the scratch
RPM to make sure it uses the new code. NB this will terminate all active guests,
so you might want to shut them down cleanly before this.

This version of libvirt failed for me, though not with the "DOS system
call" error.

Previously when I used the latest libvirt for f9, I got the error

"libvirtError: virDomainCreateLinux() failed internal error Timed out while
reading monitor startup output"

I was able to install libvirt.0.4.3-1.fc10 to work around this, after which I
discovered the "DOS system call" error

Now I have installed libvirt-0.4.4-2.fc9 I one again get the

"libvirtError: virDomainCreateLinux() failed internal error Timed out while
reading monitor startup output"

error, so it doesn't get far enough to attempt to boot from CD.

If I remember correctly the fix in libvirt.0.4.3-1.fc10 was related to something
overwriting file descriptors?

Yes I will open a new ticket, the reason I hadn't opened one previously was
because I was hoping that once libvirt-0.4.3-x or later was available for f9, it
would include the fix I knew was already in rawhide ...

I'm still seeing this on x86_64 F9.  The curious thing is that the
bodhi-generated comment (#9) mentions a version different than what I have and
what is referenced in Dan's koji link:

$ rpm -q libvirt
libvirt-0.4.4-1.fc9.x86_64

Right, this is fixed in libvirt-0.4.4-2.fc9.  Most likely whatever mirror you
are using doesn't yet have this in updates or updates-testing (I can't remember
at the moment where it is).  It might be best to point directly at the main
fedora site for this update, and then switch back to your local mirror.
