Provide version of virt-p2v ISO based on RHEL 6
Last modified: 2016-02-23 04:55:26 EST
Description of problem: We now have a virt-p2v ISO based on RHEL 7 (bug 1168626). Unfortunately this revealed a couple of fairly serious problems: - RHEL 7 dropped support for 32 bit i686, and so we can no longer use P2V to convert very old 32 bit machines. - RHEL 7 dropped support for cciss devices, and the cciss devices which are not supported by the newer hpsa driver cannot be converted at all (bug 1252701). A list of such devices can be found here: http://man7.org/linux/man-pages/man4/cciss.4.html#DESCRIPTION The solution to this is to provide a version of the virt-p2v ISO which is based on RHEL 6. This is not trivial to do, although it is not impossible. Firstly I add a bunch of commits to virt-p2v to fix problems on RHEL 6: 06e92bffd4b1924bf9b076e44e59d03ea7146db8 437cb7b6ffcb21a43a7368d4402228f043a62a9c b0cd6917cac7d314e971d90747e053907b48b2f7 00bceec4216da7757acf0aa7174a99fb0b6deeb5 2bfb9ff9ea7316cfa6a62879f77f6600c91789d9 1d082d127e017d91bc493807a4a488dfa045a79c 92e155dbddaafe0cd9f0be13fc0b723522735eff c9ad61b37b1efc5e496295117ad5d1614c3862f1 Secondly qemu-kvm on RHEL 6 does not include qemu-nbd, which is required by virt-p2v. Although we could modify the qemu-kvm package to add it, I think that's a big change to our core hypervisor this late in RHEL 6, and instead we should just compile our own qemu-nbd and include it into the ISO. Version-Release number of selected component (if applicable): I suggest we think about this for RHEL 6.8. In the meantime I'll distribute unofficial ISOs for testing purposes.
I decided to base this on Fedora instead for a few reasons: - Fedora still builds 32 bit versions of qemu-nbd, kernel etc. - Doesn't require that we backport virt-p2v code to RHEL 6 (so we can still use modern Gtk features) I have built a 32 bit ISO and placed it in the usual place: http://oirase.annexia.org/virt-p2v/ - virt-p2v-livecd-1.32.0.fc23.iso The Fedora virt-p2v and RHEL virt-v2v are interoperable.
