Description of problem: I noticed this when I was test tweaking systemd quemu-kvm vm trying to get it to boot under a second into the multi-user target ( got it down to 1553ms for those interested can shave roughly 500ms if I skip the initrd image ). This is probably just a classic minor bug somewhere where it's defined it can only boot from sda perhaps hda as well but missing all the other letters from the alphabet. Version-Release number of selected component (if applicable): 3.4.x probably affects older/newer kernels as well How reproducible: Always Steps to Reproduce: 1. Create a vm with ext4 partitions only ( unhash lvm in the partition setup in Anaconda ) 2.boot with root=/dev/vdaX rootfstype=ext4 replace X with your / partition 3. Actual results: Expected results: Additional info:
Please post the boot logs.
What boot log since the kernel cant directly boot of vda? I can provide you with phone screenshot if you so desire but you can just as well follow the reproduce steps there after all there is a reason that field exist in bug reports but if nobody uses it we can just as well advocate to have it removed.

(In reply to comment #2) > What boot log since the kernel cant directly boot of vda? It's a virtual machine. It would be great if you could configure a serial console for it and capture the full boot output by logging it. > I can provide you with phone screenshot if you so desire but you can just as > well follow the reproduce steps there after all there is a reason that field > exist in bug reports but if nobody uses it we can just as well advocate to > have it removed. Your instructions are fine. Asking you for help in your admittedly non-normal usecase for Fedora doesn't seem beyond the pale though. If you don't wish to do that, OK. We'll get to this bug when we can.

From my point of view there is nothing abnormal with my use. In fact I considered us defaulting our partition layout ( with lvm ) for the majority of our user base being utterly absurd. And if grubby was not so broken by still relying on the presence of /dev/root in the 21 century this would be far more common setup then you care to admit. Do you need more information than what's on the attached image to this report?
Why is this being closed insufficient data? Comment one descries exactly how to duplicate this. Reopening
Inadvertent. If you want to further it along, please try with the latest F17 kernel, configure the serial console as suggested in comment #4, and attach the full boot output.
This bug is being closed because it has been set needinfo for more than 2 weeks without a response. If this is still an issue, please reopen and reply with the requested information.
Reopening still an issue
Does the serial output provide more information then the attached screenshot? Just add "root=/dev/vda2 rootfstype=ext4 quiet libahci.ignore_sss=1 raid=noautodetect" to the kernel command line and you are able to reproduce this with kvm
the exact same kernel command line works just fine on physical hardware when you replace vda with sda ...
This message is a reminder that Fedora 17 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 17. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '17'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 17's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 17 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior to Fedora 17's end of life. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 17 changed to end-of-life (EOL) status on 2013-07-30. Fedora 17 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
