Description of problem: Every time I try to create a F10 virtual machine I get a "Broken Pipe" error.
Version-Release number of selected component (if applicable): libvirt-0.5.1-2.fc10.x86_64
How reproducible: Always
Steps to Reproduce:
1. Use Virtual Machine Manager to create a VM.
2. Use F10 x86_64 DVD ISO for the install
3. Click finish
Actual results: Initially get an error saying it cannot open the ISO, then receive an error showing a broken pipe.
Expected results: The virtual machine is created.
Additional info: The details in the error are:
Unable to complete install '<class 'libvirt.libvirtError'> Broken pipe

libvirtError: Broken pipe
Hmm, looks like libvirtd is segfaulting. Can you try the following:
su - (to switch to root user)
service libvirtd stop
ulimit -c unlimited
yum --enablerepo=updates-debuginfo install libvirt-debuginfo
Now leave libvirtd running, and open up virt-manager like you normally would. Reproduce the 'Broken pipe' error. The terminal you ran libvirtd in should say
Segmentation fault (core dumped)
There should be a file in that directory called core.XXXX with X being some number. In that terminal, run:
gdb -c core.whatever-that-number-is
In gdb, type 'bt' and post the contents here.
Also, can you post ~/.virt-manager/virt-manager.log so we can see the parameters you are using to reproduce?
Also, what does 'virsh pool-list --all' give?
Ping on this, any additional info from the reporter? Are you still seeing this problem?
I received a similar error:
[root@webdav images]# virt-manager --no-fork

libvirt.libvirtError: Broken pipe
When I restarted libvirtd, and re-ran the virt-manager, my virtual machine appeared in the list. I deleted the virtual machine and performed the steps that you outlined in Comment #1 to file a detailed bug report, but it created the virtual machine without any errors that time.
The 'broken pipe' shows that libvirtd daemon was segfaulting when doing this operation. I'm reasonably confident this problem will be fixed in 0.6.1 release now in F10 updates-testing, so will mark this MODIFIED. Please add more comments if this 0.6.1 release doesn't address it.
libvirt-0.6.1-1.fc10 has been pushed to the Fedora 10 testing repository. If problems still persist, please make note of it in this bug report.
If you want to test the update, you can install it with
su -c 'yum --enablerepo=updates-testing update libvirt'. You can provide feedback for this update here: http://admin.fedoraproject.org/updates/F10/FEDORA-2009-2396

When I followed these steps I didn't get a "Segmentation fault (core dumped)".

This message is a reminder that Fedora 10 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 10. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '10'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 10's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 10 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
libvirt-0.6.1 isn't pushed to stable, and is sitting in updates testing for F10. This bug won't be fixed in the stable f10 package, but is fixed in F11.
Moving to F11 and closing as CURRENTRELEASE.
