Package: src:xen
Severity: important
Version: 4.1.3~rc1+hg-20120614.a9c0a89c08f2-2
I recently upgrade from Squeeze to Wheezy on a system which had the
xen-linux-system-686-pae metapackage (one of two which Provides:
xen-linux-system). After dist-upgrade I had the new xen-utils-common and
xenstore-utils (and a few others) but not the xen-utils-4.1 or
xen-hypervisor-4.1-i386 or xen-hypervisor-amd64 package. (dpkg -l
"*xen*" output is below).
I have marked this bug important since I think failure to upgrade is "a
major effect on the usability of a package".
I think this is because the dependency chain is:
xen-linux-system-686-pae
-> xen-linux-system-3.2.0-3-686-pae
-> xen-hypervisor-amd64 | xen-hypervisor-i386
Where xen-hypervisor-{amd64,i386} are virtual packages provided by the
real xen-hypervisor-{4.0,4.1}-{amd64,i386}. The problem seems to be that
the Depends remains satisfied by the 4.0 version and therefore the 4.1
version is not installed as expected.
One possible solution would be to turn those virtual packages into real
ones, at which point I expect the versioning would cause the expected
upgrade. I hope to take a look at this soon and check that it actually
works. I notice that linux-image-amd64 (the approx equivalent to
xen-hypervisor-amd64 for the kernel) is not pure virtual so I think this
makes sense..
At the very least this issue needs to be added to the release notes
since the is currently an extra manual step required during upgrade.
Ian.
