Description Bret Palsson 2009-06-30 23:04:52 UTC

Description of problem:
Many packages with have a kernel-xen-XXXX dependancy because they were built with that kernel. However they return:

Error: Missing Dependency: kernel-xen = 2.6.18-128.1.14.el5xen is needed by package ...

This is because in the kernel-2.6.spec under Package xen it is missing the xen appendage.

If you install kernel-xen and type in `uname -r` it will output 2.6.18-128.1.14.el5xen which is the same command many spec files use to set the dependency of the kernel.

kernel-2.6.spec

Version-Release number of selected component (if applicable):
5.3

How reproducible:
Every time

Steps to Reproduce:
1. yum install kernel-xen
2. reboot
3. uname -r (note output)
4. yum list kernel-xen (note the xen is missing from the version)
  
Actual results:
The versions are a miss-match.

Expected results:
The versions should match.

Additional info:
I appended xen on the provides for the package xen in the spec file and then rebuilt, it now works.
I would suggest adding another Provides line and then have the appendage.

Hi Bret,

I think I know what you are looking for but I has hoping for some more concrete details just to make sure.

Is the patch you are suggesting something like (sorry for the cut-n-paste)?

@@ -924,6 +929,7 @@ Summary: The Linux kernel compiled for Xen VM operations

 Group: System Environment/Kernel
 Provides: kernel = %{version}
+Provides: kernel = %{version}xen
 Provides: kernel-%{_target_cpu} = %{rpmversion}-%{release}xen
 Provides: xen-hypervisor-abi = %{xen_abi_ver}
 Prereq: %{kernel_prereq}


Also, may I ask what packages you are having trouble with this dependency.  This is the first I have heard of it.  I would have assumed this issue would have been brought up a while ago.  But then again, we are creating new virt packages all the time.

Thanks,
Don

Hi Bret,

Any feedback on my above reply?

Comment 4 Bret Palsson 2009-11-24 16:26:54 UTC

Yes that looks correct. I don't remember what package I was having a problem with now. I did however repackage the RPM with the above patch file. Sorry I didn't submit one earlier.

Thanks,
Bret

$ uname -r
2.6.18-238.el5xen

$ yum list kernel-xen
kernel-xen.x86_64        2.6.18-238.el5           installed

The package is called "kernel-xen", not "kernel". I believe the affected client packages should depend (alternatively anyway) on the "kernel-xen" package, not on "kernel" with a "xen" suffixed version. Thus it's rather those packages that should be modified. Since no specific package was named, I'm closing this as NOTABUG. Please reopen if you disagree. Thank you.
