+++ This bug was initially created as a clone of Bug #247982 +++ Description of problem: We want be able to run RHEL-5 fully virtualized guests with paravirtualized drivers. Xen emulates a IDE disk controller (PIIX3) which is driven by the drivers/ide/ subsystem in RHEL-5. The ide drivers are compiled statically, thus it is impossible to select ide vs. paravirtualied driver by module load order. That in turn requires an kernel command line option to disable the ide drivers so the paravirtual driver can step in. As the paravirtual drivers are optional we can't automatically disable ide for the xen disk controller, although it can easily be identified by pci subsystem id. -- Additional comment from kraxel on 2007-07-12 10:26 EST -- Created an attachment (id=159061) patch intoduces ide=disable -- Additional comment from pm-rhel on 2007-08-30 12:07 EST -- This request was evaluated by Red Hat Product Management for inclusion in a Red Hat Enterprise Linux maintenance release.

added to RHEL4.7 Driver Updates: <quote> ide: driver updated to include ide=disable, a kernel PCI module parameter that can be used to disable ide drivers. </quote> please advise if any further revisions are required. thanks!
Hi, the RHEL4.7 release notes deadline is on June 17, 2008 (Tuesday). they will undergo a final proofread before being dropped to translation, at which point no further additions or revisions will be entertained. a mockup of the RHEL4.7 release notes can be viewed here: http://intranet.corp.redhat.com/ic/intranet/RHEL4u7relnotesmockup.html please use the aforementioned link to verify if your bugzilla is already in the release notes (if it needs to be). each item in the release notes contains a link to its original bug; as such, you can search through the release notes by bug number. Cheers, Don
