Comment 1 Fedora Blocker Bugs Application 2015-08-06 08:16:19 UTC
Proposed as a Blocker for 23-alpha by Fedora user roshi using the blocker tracking app because:

 These images won't boot locally or with openstack, in v2 qcow or v3. It violates the following criterion: "All release-blocking images must boot in their supported configurations."

Comment 2 kushaldas@gmail.com 2015-08-06 10:09:28 UTC
I can verify this issue. Strangely it is booting when using qemu-kvm directly, but not with virt-install.

Comment 3 Kevin Fenzi 2015-08-06 14:55:02 UTC
I see this also in the fedora infrastructure private cloud.

Did rc1 work? or any of the tc's? That might help us isolate where it started failing...

Comment 4 Petr Schindler 2015-08-06 15:02:06 UTC
+1 blocker from me.

Comment 5 Stephen Gallagher 2015-08-06 15:07:59 UTC
Yeah, unfortunately I have to vote +1 blocker as well.

Comment 6 Kevin Fenzi 2015-08-06 15:19:49 UTC
oh yeah, +1 blocker here too. ;( 

Answering my question above, none of tc1/tc2/rc1 had cloud images, so we can't use them to isolate it. ;(

Comment 7 Matthew Miller 2015-08-06 15:35:29 UTC
Hmmm — "KVM: entry failed, hardware error 0x7" in bug #1016748, but that's for nested virt.

Comment 8 Matthew Miller 2015-08-06 15:52:29 UTC
I bet the difference between qemu-kvm and and the failure case is in the -cpu or -machine options. Someone want to start bisecting those? :)

Comment 9 Adam Williamson 2015-08-06 16:05:11 UTC
As described so far, clear +1 blocker.

Comment 10 Adrian Reber 2015-08-06 16:35:46 UTC
This sounds a lot like what I have seen here:


Comment 11 Adam Williamson 2015-08-06 16:40:54 UTC
Yup, sure does, thanks for the note. More syslinux crap? Fun.

Comment 12 Adam Williamson 2015-08-06 16:45:32 UTC
The difference between syslinux 6.03-2.fc22 and 6.03-5.fc23 is more or less GCC 4 vs. GCC 5, the 'Harden All Packages' change, and the fix for 1234653 that we backported.

The CFLAGS for both compiles look to be identical to me.

Comment 13 Matthew Miller 2015-08-06 17:15:01 UTC
My suggestion is to switch to grub2 for the alpha, and if extlinux issues can be addressed before beta, put it back to that, but if not, leave as grub2 (and work on reducing grub2 packaging issues like fedora-logos dependency).

Comment 14 Mike Ruckman 2015-08-06 18:12:25 UTC
So it seems to boot if I manually install grub2. It's a start.

Comment 15 Matthew Miller 2015-08-07 15:23:30 UTC
So, we now have grub2-based RC2.2 images, and they work in EC2 and OpenStack.

Comment 16 Mike Ruckman 2015-08-07 16:55:42 UTC
All my testing indicates things are good to go for Alpha.

Comment 17 Mike Ruckman 2015-08-07 17:09:29 UTC
Discussed in 2015-08-06 Go/No-Go meeting. Accepted as a blocker.

Comment 18 Adam Williamson 2015-08-07 19:36:51 UTC
Setting back to ASSIGNED, but dropping blocker status, as the Alpha RC2.2 images are verified to boot.

Should this be re-assigned to syslinux?

Comment 19 Adam Williamson 2015-10-15 23:18:47 UTC
So I did a build of syslinux with a couple of patches from the upstream mailing list, and it makes livecd-iso-to-disk work. It may also solve the cloud case. Does someone want to try building an image using the syslinux packages from this scratch build?


Comment 20 Adrian Reber 2015-10-16 06:44:16 UTC
The problems I have reported in https://bugzilla.redhat.com/show_bug.cgi?id=1241159 are fixed with the version of syslinux at


My Fedora 23 VM can now boot again with syslinux (without crashing KVM).

Comment 21 Adam Williamson 2015-10-19 22:27:54 UTC
OK, so since we're sticking with grub2 for 23 and we have a fixed syslinux for Rawhide, I figure we can close this, there's no work left.
