Setup a simple two domU system. One with network backend, running xendriverdomain service, and one with frontend, trying to ping the backend.
Contrary to other similar tests, use disk image instead of initrd, to allow bigger rootfs without adding more RAM (for both dom0 and domU). But keep using pxelinux as a bootloader as it's easier to setup than installing grub on the disk. Theoretically, it could be started via direct kernel boot in QEMU, but pxelinux is slightly closer to real-world deployment. Use fakeroot to preserve file owners/permissions. This is especially important for suid binaries like /bin/mount - without fakeroot, they will end up as suid into non-root user. Signed-off-by: Marek Marczykowski-Górecki <[email protected]> --- Changes in v3: - add fakeroot - run ldconfig at the disk image creation time, to avoid running it at dom0/domU boot time (which is much slower) Changes in v2: - use heredoc - limit ping loop iterations - use full "backend" / "frontend" in disk image names - print domU consoles directly to /dev/console, to avoid systemd-added messages prefix - terminate test on failure, don't wait for timeout --- automation/build/debian/13-x86_64.dockerfile | 2 +- automation/gitlab-ci/test.yaml | 8 +- automation/scripts/qemu-driverdomains-x86_64.sh | 138 +++++++++++++++++- 3 files changed, 148 insertions(+) create mode 100755 automation/scripts/qemu-driverdomains-x86_64.sh diff --git a/automation/build/debian/13-x86_64.dockerfile b/automation/build/debian/13-x86_64.dockerfile index 2c6c9d4a5098..6382bafbd5bd 100644 --- a/automation/build/debian/13-x86_64.dockerfile +++ b/automation/build/debian/13-x86_64.dockerfile @@ -55,7 +55,9 @@ RUN <<EOF # for test phase, qemu-* jobs busybox-static + e2fsprogs expect + fakeroot ovmf qemu-system-x86 diff --git a/automation/gitlab-ci/test.yaml b/automation/gitlab-ci/test.yaml index 7b36f1e126ca..abc5339a74ab 100644 --- a/automation/gitlab-ci/test.yaml +++ b/automation/gitlab-ci/test.yaml @@ -656,6 +656,14 @@ qemu-alpine-x86_64-gcc: - *x86-64-test-needs - alpine-3.22-gcc +qemu-alpine-driverdomains-x86_64-gcc: + extends: .qemu-x86-64 + script: + - ./automation/scripts/qemu-driverdomains-x86_64.sh 2>&1 | tee ${LOGFILE} + needs: + - *x86-64-test-needs + - alpine-3.22-gcc + qemu-smoke-x86-64-gcc: extends: .qemu-smoke-x86-64 script: diff --git a/automation/scripts/qemu-driverdomains-x86_64.sh b/automation/scripts/qemu-driverdomains-x86_64.sh new file mode 100755 index 000000000000..c0241da54168 --- /dev/null +++ b/automation/scripts/qemu-driverdomains-x86_64.sh @@ -0,0 +1,138 @@ +#!/bin/bash + +set -ex -o pipefail + +dom0_rootfs_extra_comp=() +dom0_rootfs_extra_uncomp=() + +cd binaries + +# DomU rootfs + +mkdir -p rootfs +cd rootfs +mkdir -p etc/local.d +passed="ping test passed" +failed="TEST FAILED" +cat > etc/local.d/xen.start << EOF +#!/bin/bash + +set -x + +if grep -q test=backend /proc/cmdline;
