Description Luke Macken 2010-04-13 14:27:48 EDT
Description of problem: All of my local kvm guests are now unusable, including a fresh F13 Beta kvm guest that I just installed. When trying to start up a guest, I get the following traceback: Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/engine.py", line 589, in run_domain vm.startup() File "/usr/share/virt-manager/virtManager/domain.py", line 150, in startup self._backend.create() File "/usr/lib64/python2.6/site-packages/libvirt.py", line 293, in create if ret == -1: raise libvirtError ('virDomainCreate() failed', dom=self) libvirtError: internal error unable to start guest: qemu: could not open disk image : No such file or directory The details show my VirtIO Disk 1 as /var/lib/libvirt/images/F13.img, which definitely exists: $ ls -lhZ /var/lib/libvirt/images/F13.img -rw-------. root root system_u:object_r:virt_image_t:s0 /var/lib/libvirt/images/F13.img This is not an SELinux issue, as far as I can tell, as I am not seeing any AVCs and I tried with it disabled as well. Version-Release number of selected component (if applicable): libvirt-0.7.1-15.fc12.x86_64 virt-manager-0.8.2-3.fc12.noarch kernel-220.127.116.11-99.fc12.x86_64 qemu-kvm-0.12.3-2.fc12.x86_64 How reproducible: Always Steps to Reproduce: 1. Do a fresh F13 Beta KVM installation 2. Reboot 3. Traceback appears
Comment 1 Luke Macken 2010-04-13 14:33:31 EDT
So I was able to get rid of this error by removing the virtual CD-ROM device, even though there is no device/ISO connected, and it's configured to boot from the Hard Disk.
Comment 2 Cole Robinson 2010-04-13 15:44:29 EDT
Hmm, I can't seem to reproduce.. Can you attach ~/.virt-manager/virt-manager.log so I can see what happened during all this? Can you also provide /var/log/libvirt/qemu/$vmname.log?
Comment 3 Luke Macken 2010-04-13 16:09:14 EDT
Created attachment 406338 [details] virt-manager.log This log shows a fresh F13 installation... restarting and triggering this Exception. I then remove the CD rom drive, and it boots successfully.

Created attachment 406339 [details] /var/log/libvirt/qemu/F13Beta.log
Comment 5 Cole Robinson 2010-04-13 17:08:30 EDT
Luke, if you also update libvirt using the rawvirt repo (which it looks like you are using), this issue goes away. Basically, -drive file=,... used to mean 'no media', now qemu actually tries to open something and errors out. Technically a qemu regression, though I guess it could have been intentional (which is unfortunate since at least one libvirt version was relying on the behavior). Re-assigning to qemu. Markus, any idea if this CLI handling change was intentional or not?

git-bisect points to 9dfd7c7a00dd700de36ca58005a7cb3934a62efb is the first bad commit commit 9dfd7c7a00dd700de36ca58005a7cb3934a62efb Author: Gerd Hoffmann <firstname.lastname@example.org> Date: Wed Jul 22 16:43:04 2009 +0200 switch -drive to QemuOpts. Demo QemuOpts in action ;) Implementing a alternative way to specify the filename should be just a few lines of code now once we decided how the cmd line syntax should look like. Signed-off-by: Gerd Hoffmann <email@example.com> Signed-off-by: Anthony Liguori <firstname.lastname@example.org> Doesn't look like an intentional change of file= behaviour.
Comment 7 Daniel Berrange 2010-05-11 07:35:53 EDT
FYI: as per Cole's comment #5, latest libvirt takes care to omit the 'file=' parameter completely when no media is inserted, thus avoiding this change in QEMU semantics.
Comment 8 Markus Armbruster 2010-06-28 14:26:30 EDT
Upstream commit dd5b0d71d660a4e31bdf8bd0d130ce582833db9f fixes this.
Comment 9 Bug Zapper 2010-07-30 07:19:59 EDT
This bug appears to have been reported against 'rawhide' during the Fedora 14 development cycle. Changing version to '14'. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Comment 10 Justin M. Forbes 2010-09-02 12:34:27 EDT
This fix is applied in currently shipping F13 and F14 qemu packages.
