reassigning to virt-manager for now...
Could it be that the rawhide tree itself is malformed or necessary files are missing? I believe there have been other problems like this. More info: I'm running RHEL5.2 beta Dom0 and trying to install a xen rawhide instance (failure described above). Attempting an F8 (gold) xen install works fine. Here is a listing of the RHEL5.2 packages for Dom0 (if that is applicable): $ rpm -qa | egrep 'virt|xen' | sort kernel-xen-2.6.18-83.el5 kernel-xen-2.6.18-85.el5 libvirt-0.3.3-5.el5 libvirt-python-0.3.3-5.el5 python-virtinst-0.300.2-5.el5 virt-manager-0.5.3-4.el5 virt-viewer-0.0.2-1.el5 xen-3.0.3-56.el5 xen-libs-3.0.3-56.el5
Probably virt-manager is looking for a "Fedora" directory, but it was renamed to "Packages", like on bug #273781.
This is the same as F8 bug 437217
Removing F9 blocker bug, since this is a RHEL 5.2 bug, not a Fedora bug.
Created attachment 298266 [details] Correctly detect rawhide/f9 distro trees Fixes distro detection for f9. Verified this doesn't affect installing f7 or f8 guests from a tree.
This is a simple fix to enable installing rawhide and f9 guests, which if we don't fix now we will definitely see a flood of bzs about later. I'm requesting this as an exception for inclusion in 5.2.
Set dev ack for Cole.
For further clarification, our package probes an install tree to try and verify what distro it is, so we know where to look for virt install media. We do this detection by looking for certain files (for fedora, we would use fedora.css). Rawhide and eventually f9 no longer carry this fedora.css file, so detection and installs were failing. This patch just changes this check to also pass if we find a file .treeinfo, which is intended to be present in all fedora trees for detections of this type (so i've been told). The check will fall back to fedora.css if it can't find treeinfo, so there should be no backwards compatibility issues (I verified this for f7 and f8). For these reasons it is low risk, and any remaining risk would be offset by the amount of time this would save us in future support. Not to mention it would look bad if this went out the door without being able to create a rawhide guest :)
Restore flags cleared by mistake.
