We don't currently have hypervisor-capable riscv64 hardware to run these on, so we're using qemu system emulation on commodity amd64 hardware. This works OK, but we currently do this in manually-configured libvirt instances; we'd much rather be able to do it on our internal OpenStack clouds.</p> <p>[Test Case]</p> <p>  $ wget <a rel="nofollow" href="http://cloud-images.ubuntu.com/server/releases/jammy/release-20220420/ubuntu-22.04-server-cloudimg-riscv64.img">http://<wbr />cloud-images.<wbr />ubuntu.<wbr />com/server/<wbr />releases/<wbr />jammy/release-<wbr />20220420/<wbr />ubuntu-<wbr />22.04-server-<wbr />cloudimg-<wbr />riscv64.<wbr />img</a><br />   $ openstack image create --disk-format qcow2 --file ~cjwatson/<wbr />ubuntu-<wbr />22.04-server-<wbr />cloudimg-<wbr />riscv64.<wbr />img --private --property architecture=<wbr />riscv64 --property item_name=disk1.img --property os_distro=ubuntu --property os_version=22.04 cjwatson-<wbr />riscv64-<wbr />test<br />   $ openstack image set --property hw_emulation_<wbr />architecture=<wbr />riscv64 cjwatson-<wbr />riscv64-<wbr />test<br />   $ openstack image set --property hw_machine_<wbr />type=virt cjwatson-<wbr />riscv64-<wbr />test<br />   $ openstack server create --image cjwatson-<wbr />riscv64-<wbr />test --flavor vbuilder --network vbuilder_<wbr />staging_<wbr />test_net cjwatson-<wbr />riscv64-<wbr />test</p> <p>Expected result: the created instance reaches to ACTIVE state.</p> <p>Actual result: the "openstack server create" command fails with the following error message:<br />   Invalid image metadata.

We don't currently have hypervisor-capable riscv64 hardware to run these on, so we're using qemu system emulation on commodity amd64 hardware. This works OK, but we currently do this in manually-configured libvirt instances; we'd much rather be able to do it on our internal OpenStack clouds.\n\n[Test Case]\n\n\u00a0\u00a0$ wget http://cloud-images.ubuntu.com/server/releases/jammy/release-20220420/ubuntu-22.04-server-cloudimg-riscv64.img\n\u00a0\u00a0$ openstack image create --disk-format qcow2 --file ~cjwatson/ubuntu-22.04-server-cloudimg-riscv64.img --private --property architecture=riscv64 --property item_name=disk1.img --property os_distro=ubuntu --property os_version=22.04 cjwatson-riscv64-test\n\u00a0\u00a0$ openstack image set --property hw_emulation_architecture=riscv64 cjwatson-riscv64-test\n\u00a0\u00a0$ openstack image set --property hw_machine_type=virt cjwatson-riscv64-test\n\u00a0\u00a0$ openstack server create --image cjwatson-riscv64-test --flavor vbuilder --network vbuilder_staging_test_net cjwatson-riscv64-test\n\nExpected result: the created instance reaches to ACTIVE state.\n\nActual result: the \"openstack server create\" command fails with the following error message:\n\u00a0\u00a0Invalid image metadata. Error: Architecture name 'riscv64' is not valid (HTTP 400) (Request-ID: req-023932ea-7c90-4be3-89b8-6bd19718919a)\n\nThis causes me to think that, even if I've left out some property or other (e.g. firmware), basic things like the riscv64 architecture name being valid aren't currently in place. But it's certainly possible I've got something wrong here. If there's a known way to make this work, could it please be documented?\n\nI've attached `virsh dumpxml` output from one of the manual libvirt instances we use at present, in case it's useful.", "owner_link": "https://bugs.launchpad.net/api/devel/~cjwatson", "bug_tasks_collection_link": "https://bugs.launchpad.net/api/devel/bugs/2023211/bug_tasks", "duplicate_of_link": null, "date_created": "2023-06-07T15:35:28.537101+00:00", "activity_collection_link": "https://bugs.launchpad.net/api/devel/bugs/2023211/activity", "subscriptions_collection_link": "https://bugs.launchpad.net/api/devel/bugs/2023211/subscriptions", "date_last_updated": "2024-07-12T09:03:44.891372+00:00", "who_made_private_link": null, "date_made_private": null, "heat": 20, "bug_watches_collection_link": "https://bugs.launchpad.net/api/devel/bugs/2023211/bug_watches", "cves_collection_link": "https://bugs.launchpad.net/api/devel/bugs/2023211/cves", "vulnerabilities_collection_link": "https://bugs.launchpad.net/api/devel/bugs/2023211/vulnerabilities", "duplicates_collection_link": "https://bugs.launchpad.net/api/devel/bugs/2023211/duplicates", "attachments_collection_link": "https://bugs.launchpad.net/api/devel/bugs/2023211/attachments", "security_related": false, "latest_patch_uploaded": null, "tags": [], "date_last_message": "2024-07-12T09:03:43.578415+00:00", "number_of_duplicates": 0, "message_count": 15, "users_affected_count": 2, "users_unaffected_count": 0, "users_affected_collection_link": "https://bugs.launchpad.net/api/devel/bugs/2023211/users_affected", "users_unaffected_collection_link": "https://bugs.launchpad.net/api/devel/bugs/2023211/users_unaffected", "users_affected_count_with_dupes": 2, "other_users_affected_count_with_dupes": 2, "users_affected_with_dupes_collection_link": "https://bugs.launchpad.net/api/devel/bugs/2023211/users_affected_with_dupes", "messages_collection_link": "https://bugs.launchpad.net/api/devel/bugs/2023211/messages", "lock_status": "Unlocked", "lock_reason": null, "linked_branches_collection_link": "https://bugs.launchpad.net/api/devel/bugs/2023211/linked_branches", "linked_merge_proposals_collection_link": "https://bugs.launchpad.net/api/devel/bugs/2023211/linked_merge_proposals", "http_etag": "\"8d757e5b6493acf58a6101795a717b651358cbb9-2663b88beac7c65ab890a453e21673bc7df87ef4\""}, "subscribers_portlet_url_data": {"web_link": "https://bugs.launchpad.net/bugs/2023211", "self_link": "https://bugs.launchpad.net/api/devel/bugs/2023211"}, "total_comments_and_activity": 30, "initial_comment_batch_offset": 41, "first visible_recent_comment": -26, "bugtask_data": {"3054559": {"id": 3054559, "row_id": "tasksummary3054559", "form_row_id": "task3054559", "bugtask_path": "/nova/+bug/2023211", "prefix": "nova", "targetname": "OpenStack Compute (nova)", "bug_title": "Run emulated riscv64 VMs on amd64", "assignee_value": "freyes", "assignee_is_team": false, "assignee_vocabulary": "AllUserTeamsParticipation", "assignee_vocabulary_filters": [], "hide_assignee_team_selection": true, "user_can_unassign": false, "user_can_delete": false, "delete_link": "https://bugs.launchpad.net/nova/+bug/2023211/+delete", "target_is_product": true, "status_widget_items": [{"name": "In Progress", "value": "In Progress", "description": "The assigned person is working on it.\n", "description_css_class": "choice-description", "style": "", "help": "", "disabled": false, "css_class": "statusINPROGRESS"}], "status_value": "In Progress", "importance_widget_items": "[]", "importance_value": "Undecided", "milestone_widget_items": "[]", "milestone_value": null, "user_can_edit_assignee": false, "user_can_edit_milestone": false, "user_can_edit_status": false, "user_can_edit_importance": false}, "3032581": {"id": 3032581, "row_id": "tasksummary3032581", "form_row_id": "task3032581", "bugtask_path": "/charm-nova-compute/+bug/2023211", "prefix": "charm-nova-compute", "targetname": "OpenStack Nova Compute Charm", "bug_title": "Run emulated riscv64 VMs on amd64", "assignee_value": null, "assignee_is_team": null, "assignee_vocabulary": "AllUserTeamsParticipation", "assignee_vocabulary_filters": [], "hide_assignee_team_selection": true, "user_can_unassign": false, "user_can_delete": false, "delete_link": "https://bugs.launchpad.net/charm-nova-compute/+bug/2023211/+delete", "target_is_product": true, "status_widget_items": [{"name": "Invalid", "value": "Invalid", "description": "Not a bug.
