Hey Hilko, >> I'm guessing that you're using Ubuntu, am I right? Pretty good guess. :) For the time being I'm using 13.10. I know I've said it previously, but your right, I should include that info so I don't make people have to go digging. How do you normally deal with that warning? I typically rename the kvm binary, then link qemu-system-x86_64 but my concern is that will cause problems if I want a 32 bit vm... (I don't see a reason to run i386 these days, but I _guarntee_ you, I have a customer who /refuses/ to use 64bit vms...) >> The ceph package in Debian has been a mess until very recently Really? I have no problems with ceph. Until I upgraded to 13.10, I was using the opscode ppa; there are no 13.10 repis I'm the ppa... Ok... I take that back.... Ceph::RADOS is largely incomplete, and my C is *really* rusty, so I've had some trouble extending the library... but other than that, ceph has been rock solid for me since at least 12.04. >> support was dropped from the qemu pacakges. It's funny you should say that. I can't for the life of me get qemu-img to create firmat 2 rbd images... but I think that may be a ceph config problem, not an issue with qemu/kvm. >> therefore its qemu packages have no rbd support either. libvirt has no problem with my rbds. It's just libguestfs that doesn't like my rbds... unless I prefix the name of the pool with a "/". I'm open to suggestions, I do most of my work in Perl with the expectation my code will run on other platforms, so I'm not married to Ubuntu/debian. Thanks for your feedback.

The "W: kvm binary is deprecated, please use qemu-system-x86_64 instead" message looks like the one I know from Debian. From the names of the kernel images, I'm guessing that you're using Ubuntu, am I right? The ceph package in Debian has been a mess until very recently, so rbd support was dropped from the qemu pacakges. Possibly Ubuntu just imports them from Debian and therefore its qemu packages have no rbd support either. Cheers, -Hilko </blockquote></div>
