Hi, I don't want to wait too long, so while waiting for an answer I made a ppa available that should be tested to confirm this fix is good (for bionic). Please test on Bionic from ppa: https://launchpad.net/~ci-train-ppa-service/+archive/ubuntu/3079 I'll mark the bug incomplete to clearly reflect I wait on an answer.

[Bug 1734856] Re: Can't boot VM with more than 16 disks (slof buffer issue)
I tried to verify the case and fix myself which is a prereq for good steps to reproduce for the SRU anyway. I came up with test steps based on what was initially reported. $ uvt-simplestreams-libvirt --verbose sync --source http://cloud-images.ubuntu.com/daily arch=ppc64el label=daily release=bionic $ uvt-kvm create --password=ubuntu cpaelzer-bionic release=bionic arch=ppc64el label=daily $ for i in {1..20}; do h=$(printf "\x$(printf %x $((98+$i)))"); echo "" > disk.xml; qemu-img create -f qcow2 /var/lib/uvtool/libvirt/images/cpaelzer-bionic-t$i.qcow 1M; virsh attach-device artful-testguest disk.xml; done $ virsh console # in guest then $ sudo reboot That works for me with overall 22 disks. I see a bunch of those: virtioblk_transfer: Access beyond end of device! virtioblk_transfer failed! type=0, status = 1 But it boots fine still and all disks are attached just fine. If instead I add all disks to the device statically before starting it it is the same. Do I just need more devices - any options to be set?

It was still working with 20 disks and boot index, but 48 made it. Thanks Nikunj for the bood index hint.

Remove in the os section 2. Add this on your former primary disk: 3.

[Bug 1734856] Re: Can't boot VM with more than 16 disks (slof buffer issue)
Thanks for sorting out the Artful test already bssrikanth. To be clear (the comments by kalshett are unclear to me at least. You need to test Xenial/Zesty/Artful HOSTS. The fix is in the slof package that is installed in the KVM host. It actually doesn't even matter which level of guest you start, but you have to do it on the host release you verify. >From my POV verification-needed-xenial was only removed by "you" (=bugproxy) >but not yet set to be done (or anything else) and the commends are unclear to >me :-/. I'll fix that up to have it as -needed again. TL;DR: Yes it is needed for Xenial and Zesty as well. Once Xenial and Zesty are done as well, then also set the global verification-done to be complete. ** Tags added: verification-needed-xenial -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1734856 Title: Can't boot VM with more than 16 disks (slof buffer issue) To manage notifications about this bug go to: https://bugs.launchpad.net/slof/+bug/1734856/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1734856] Re: Can't boot VM with more than 16 disks (slof buffer issue)
It is mostly independent to the kernel, the fix by Nikunj just needs the new Slof to be on the host. Please sync internally if the test is correct as this is the fix that was suggested by you and at least in my tests it worked. Since former verifications were a bit back and forth and this confusion now looks similar please make sure what the actual state of this is now on Xeniakl and Zesty. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1734856 Title: Can't boot VM with more than 16 disks (slof buffer issue) To manage notifications about this bug go to: https://bugs.launchpad.net/slof/+bug/1734856/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
