From 3aff5dda199b50e598f527f3687183ff1a618653 Mon Sep 17 00:00:00 2001 From: Dmitry Rakitin Date: Fri, 10 Jul 2026 14:59:45 +0200 Subject: [PATCH 01/38] test(e2e): source VirtualDiskCreation from the custom e2e-br image MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Point every VirtualDiskCreation data source (HTTP, Upload, registry, VirtualImage, ClusterVirtualImage) at the minimal custom e2e-br image: a Selectel qcow2 for HTTP/Upload and a ttl.sh container-disk for the registry source. Drop the cloud-init provisioning for the test's VM — it only needs the VM as a disk consumer with a live guest agent and never logs in, so no user has to be created. New object symbols (ImageURLCustomBIOS, ImageURLCustomContainer, PrecreatedCVICustomBIOS) are additive; existing constants are left untouched, so other e2e tests keep their behavior.

Point the ISO/CD-ROM boot and format-expectation tests at the custom ISO instead of the Ubuntu live-server ISO, and drop the VNC subiquity-installer screen assertion (Ubuntu-specific) — the CD-ROM boot test now only asserts the VM reaches Running with a bootable device (Never NoBootableDevice), which is what booting a custom ISO as CD-ROM verifies. Removes the RFB/VNC framebuffer machinery that check required.

The minimal e2e-br image runs no udev, so lsblk's SERIAL column and /dev/disk/by-id are empty; this also drops the awk one-liner whose single quotes clashed with d8 ssh -c '...'. - Add vd observer predicate BeResized and wait on it after a resize instead of BeReady, which errors on the transient Resizing phase. - Skip DataExports when the suite runs off-cluster: publish-mode export is currently broken by a bug in the storage-volume-data-manager module (origin Ingress looked up in d8-user-authn instead of kube-system). TODO to drop the skip once fixed. - Filter the benign pvc-protection cleanup error and raise the VM-deletion wait to LongTimeout.

As a result every VirtualImage created from a block-device source (a VirtualDisk or VirtualDiskSnapshot) reported unpackedSize exactly 10 MiB larger than the actual data, and disks cloned from such images failed size validation ("the specified pvc size is insufficient") unless oversized. Sample the temp file straight from the combined reader and count each byte once.
