It shows itself in open-iscsi autopkg tests. I think it might just be "really slow system". It seems the timeout is only 1 minute 30 seconds for the disk to appear, and in a happy run you might see something very close: [K[ [0;31m*[0;1;31m*[0m[0;31m*[0m] A start job is running for dev-disk…-UEFI.device (1min 29s / 1min 32s) [K[ [0;31m*[0;1;31m*[0m[0;31m* [0m] A start job is running for dev-disk…-UEFI.device (1min 30s / 1min 32s) [K[[0;32m OK [0m] Found device VIRTUAL-DISK UEFI.

Success is being able to log in with 'ubuntu' and 'passw0rd'. Failure as seen in the log is dropping into an emergency shell. Once inside (this was successful) you'll see a mostly sane system. Some things to note: a.) tgt-boot-test boots without kvm enabled. This is because using kvm with qemu in nested virt would cause system lockups. Its slower but more reliable to go wtihout. b.) under bug 1723183 I made overlayroot comment out the root filesystem from the rendered /etc/fstab. That was because systemd got confused and assumed that /media/root-ro had to be on top of /. c.) you can enable or disable kvm by setting _USE_KVM=0 or _USE_KVM=1 in your environment. $ grep -v "^# " /etc/fstab # # #LABEL=cloudimg-rootfs /media/root-ro/ ext4 ro,defaults,noauto 0 0 /media/root-ro/ / overlay lowerdir=/media/root-ro/,upperdir=/media/root-rw/overl ay/,workdir=/media/root-rw/overlay-workdir/_ 0 0 LABEL=UEFI /boot/efi vfat defaults 0 0 # overlayroot:fs-unsupported $ sudo blkid /dev/sda1: LABEL="cloudimg-rootfs" UUID="7b1980bd-9102-4356-8df0-ec7a0c062411" TYPE="ext4" PARTUUID="c0b5ace0-4703-4667-babb-3d38137cab88" /dev/sda15: LABEL="UEFI" UUID="B177-3CC9" TYPE="vfat" PARTUUID="0ab0b9fd-2c28-4724-857a-1559f0cf76ea" /dev/sda14: PARTUUID="221662d6-cab0-4290-ba1c-e72acf2bf193" $ cat /run/systemd/generator/local-fs.target.requires/boot-efi.mount # Automatically generated by systemd-fstab-generator [Unit] SourcePath=/etc/fstab Documentation=man:fstab(5) man:systemd-fstab-generator(8) Before=local-fs.target [Mount] Where=/boot/efi What=/dev/disk/by-label/UEFI Type=vfat Related bugs: * bug 1680197: Zesty deployments failing sporadically * bug 1723183: transient systemd ordering issue when using overlayroot * bug 1666573: transient systemd ordering cycle in boot with overlayroot ver read-only open-iscsi root ProblemType: Bug DistroRelease: Ubuntu 18.04 Package: systemd 234-2ubuntu12 ProcVersionSignature: User Name 4.13.0-16.19-generic 4.13.4 Uname: Linux 4.13.0-16-generic x86_64 ApportVersion: 2.20.7-0ubuntu4 Architecture: amd64 Date: Mon Nov 13 21:06:36 2017 Lsusb: Error: command ['lsusb'] failed with exit code 1: MachineType: QEMU Standard PC (i440FX + PIIX, 1996) ProcEnviron: TERM=vt220 PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=C.UTF-8 SHELL=/bin/bash ProcKernelCmdLine: nomodeset iscsi_initiator=maas-enlist iscsi_target_name=tgt-boot-test-7xuhwl iscsi_target_ip=10.0.12.2 iscsi_target_port=3260 iscsi_initiator=maas-enlist ip=::::maas-enlist:BOOTIF ro net.ifnames=0 BOOTIF_DEFAULT=eth0 root=/dev/disk/by-path/ip-10.0.12.2:3260-iscsi-tgt-boot-test-7xuhwl-lun-1-part1 overlayroot=tmpfs console=ttyS0 ds=nocloud-net;seedfrom=http://10.0.12.2:32600/ SourcePackage: systemd UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 04/01/2014 dmi.bios.vendor: SeaBIOS dmi.bios.version: 1.10.2-1ubuntu1 dmi.chassis.type: 1 dmi.chassis.vendor: QEMU dmi.chassis.version: pc-i440fx-artful dmi.modalias: dmi:bvnSeaBIOS:bvr1.10.2-1ubuntu1:bd04/01/2014:svnQEMU:pnStandardPC(i440FX+PIIX,1996):pvrpc-i440fx-artful:cvnQEMU:ct1:cvrpc-i440fx-artful: dmi.product.name: Standard PC (i440FX + PIIX, 1996) dmi.product.version: pc-i440fx-artful dmi.sys.vendor: QEMU To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/open-iscsi/+bug/1732028/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
