I've taken your kernel (vmlinuz-4.4.0-1009-kvm) and booted a "normal" cloud image with that kernel. It hangs similarly (but for noticibly shorter time).
http://cloud-images.ubuntu.com/daily/server/artful/20171026.1/artful- server-cloudimg-amd64.img I did have to disable the UEFI partition (vfat) since there were modules for your kernel in /lib. $ qemu-img create -f qcow2 -b artful-cloud-image.img my.img $ sudo mount-image-callback -vv my.img -- mchroot sed -i "/LABEL=UEFI/s/^/#/" /etc/fstab $ xkvm --netdev=user --disk=my.img --disk=my-seed.img -- -snapshot -m 768 -nographic -echr 0x05 -smp 2 -kernel vmlinuz-4.4.0-1009-kv m -append "root=PARTUUID=9697fbdd-a35d-46d6-a51c-08bfab833468 console=ttyS0 syst emd.log_target=console systemd.log_level=info systemd.log_target=console" qemu-system-x86_64 -enable-kvm -device virtio-scsi-pci,id=virtio-scsi- xkvm -device virtio-net-pci,netdev=net00 -netdev type=user,id=net00 -drive file=my.img,id=disk00,if=none,format=qcow2,index=0 -device virtio-blk,drive=disk00,serial=my.img -drive file=my- seed.img,id=disk01,if=none,format=raw,index=1 -device virtio- blk,drive=disk01,serial=my-seed.img -snapshot -m 768 -nographic -echr 0x05 -smp 2 -kernel vmlinuz-4.4.0-1009-kvm -append "root=PARTUUID =9697fbdd-a35d-46d6-a51c-08bfab833468 console=ttyS0 systemd.log_target=console systemd.log_level=info systemd.log_target=console" ... log looks like this, and hangs there. http://paste.ubuntu.com/25832616/ Heres a diff of configs for the not working kernel and the working kernel. $ diff -u config-4.4.0-59-generic config-4.4.0-1009-kvm | pastebinit -f diff http://paste.ubuntu.com/25825403/ -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1727358 Title: cloud-init is slow to complete init on minimized images To manage notifications about this bug go to: https://bugs.launchpad.net/cloud-init/+bug/1727358/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
