using stop_reason as a vdsm hook trigger into the UI
by Nathanaël Blanchet 22 Dec '21

22 Dec '21

Hello, I'm writing some code to make the following workflow: * setting a custom stop_reason as 'force_delete' when stopping/deleting a vm * this will trigger a vdsm hook into after_vm_destroy event. * this hook will call back AWX/ansible to: o remove DNS entries o remove vm file backup o delete supervision o (optionnal) delete the vm * the vm is destroyed and removed by vdsm. Here is the code (I'm not a python expert) #!/usr/libexec/platform-python # 211217 NBT # This is a vdsm hook that aims to auto delete oVirt dependencies when removing a VM directly from engine. # It is triggered when filling the stop_reason field in oVirt with strict 'clean'. # It initially concerns following actions: # - Centreon subscription Removing # - Backup erase from Sotora # - DNS cleaning on Lilas # - IPA deletion # This set of actions can be extended into the concerned AWX job_template (180 or 160) # When finished, vm can be manually removed from Engine. # When string is 'force_delete' or 'force_remove', then in addition, the vm will be automatically erased at the same time. importos fromvdsm.hook importhooking fromxml.dom importminidom importrequests fromxml.etree importElementTree importsys importurllib3 importtime importtraceback importsubprocess fromsubprocess importPIPE, STDOUT importlogging urllib3.disable_warnings() logger = logging.getLogger("register_migration") defexec_cmd(*args): retcode, out, err = hooking.execCmd(args, sudo=True) ifretcode != 0: raiseRuntimeError("Failed to execute %s, due to: %s"% (args, err)) returnout if__name__== '__main__': logging.basicConfig(filename="/var/log/vdsm/custom_hooks.log", level=logging.INFO, format='%(asctime)s%(levelname)s%(name)s:%(message)s', datefmt= '%Y-%m-%d%H:%M:%S') iflen(sys.argv) > 1: vm_name= sys.argv[1] else: domxml = hooking.read_domxml() vm_name = domxml.getElementsByTagName('name')[0].firstChild.nodeValue print(vm_name) # API oVirt: Initialize variables user = 'admin@internal' password = 'password' url = "https://air-dev.v100.abes.fr/ovirt-engine/api/vms?search=name%3D"+ vm_name headers = {'Accept': 'application/xml'} print('name: '+ vm_name) # API oVirt: Test if VM stop_reason has been defined whileTrue: # r = requests.get(url, headers=headers, auth=('admin@internal', 'password'), verify=False) # tree = ElementTree.fromstring(r.content) r = exec_cmd('curl', '--insecure', '--header', 'Accept: application/xml', '--user', 'admin@internal:password', 'https://air-dev.v100.abes.fr/ovirt-engine/api/vms?search=name%3D'+ vm_name) tree = ElementTree.fromstring(b''.join(r)) forvm intree.findall('vm'): status = vm.find('status') stop_reason = vm.find('stop_reason') print(status.text) ifstop_reason isnotNone: print(status.text, stop_reason.text) break time.sleep(1) forvm intree.findall('vm'): stop_reason = vm.find('stop_reason') ifstop_reason isNone: exit('stop_reason is not defined') else: # API AWX: Initialize variables header1 = 'Content-Type: application/json' header2 = 'Authorization: Bearer token' curl_server = "nbt" curl_extra_vars = "{\\\"comment\\\": \\\"Nbt\\\", \\\"survey_ovirt_password\\\": \\\"password\\\", \\\"force_erase\\\": \\\"yes\\\", \\\"survey_vms_list\\\": %s}"% (vm_name) curl_config = '{"extra_vars": "%s"}'% (curl_extra_vars) ifstop_reason in["clean"]: curl_job_template = "180" print('Cleaning'+ vm_name + 'from oVirt on ancolie-'+ curl_server + 'with workflow_job_template '+ curl_job_template) curl_url = "http://ancolie-{}.v106.abes.fr/api/v2/workflow_job_templates/{}/launch/".format(curl_server,curl_job_template) exec_cmd('curl', '-f', '-H', header1, '-H', header2, '-XPOST', '-d', curl_config, curl_url) elifstop_reason in["force_delete", "force_remove"]: curl_job_template = "160" print('Deleting and cleaning'+ vm_name + 'from oVirt on ancolie-'+ curl_server + 'with workflow_job_template '+ curl_job_template ) curl_url = "http://ancolie-{}.v106.abes.fr/api/v2/workflow_job_templates/{}/launch/".format(curl_server,curl_job_template) exec_cmd('curl', '-f', '-H', header1, '-H', header2, '-XPOST', '-d', curl_config, curl_url) else: exit('Stop reason is '+ stop_reason + ' and there is no reason to do anything for '+ vm_name) The idea is to use the stop_reason element into the vm xml definition. But after hours, I realized that this element is writed to the vm definition file only after the VM has been destroyed. So if I test this value (if existing) when executing the hook, the text value doesn't still exist at early time I added a 'while' loop to wait for the stop_reason element to be present, but vdsm hangs out because of an infinity loop: 2021-12-20 18:13:30,148+0100 INFO (jsonrpc/7) [root] /usr/libexec/vdsm/hooks/after_vm_destroy/clean_vm_dependencies_2.py: rc=1 err=b'Traceback (most recent call last):\n File "/usr/libexec/vdsm/hooks/after_vm_destroy/clean_vm_dependencies_2.py", line 84, in <module>\n print(status.text, stop_reason.text)\nAttributeError: \'NoneType\' object has no attribute \'text\'\n' (hooks:122) .... So I'm deducing I'm not able to accomplish my initial goal to use stop_reason as a trigger with after_vm_destroy event. I searched an other way to do: I thought of replacing querying ovirt API with getting the value coming from the UI, but I can't find the suitable database query. Is there a way to do such a thing? Does engine hooks exist for stopped vm?? Thank you for your help. PS: I'm already able to do this from ansible/AWX, but I have to do it from UI/vdsm for any reason. -- Nathanaël Blanchet Supervision réseau SIRE 227 avenue Professeur-Jean-Louis-Viala 34193 MONTPELLIER CEDEX 5 Tél. 33 (0)4 67 54 84 55 Fax 33 (0)4 67 54 84 14 blanchet(a)abes.fr

virsh list --all only shows running on host
by richmoch＠yahoo.com 22 Dec '21

22 Dec '21

Hi *, I am having a problem where on a KVM host I run virsh list --all. I only see the running VMs : [root@MBGVRT3323 ~]# virsh list --all Please enter your authentication name: Please enter your password: Id Name State ----------------------------------- 3 MBPDBS0583U-CLONE running 4 MBGDBS3156U-CLONE running I know there are two more VMs that are shutdown , and if I run virsh list --state-shutoff , nothing is returned. in fact, look at the numbering of the two running VMs, 3 and 4. The GUI shows the two running and the other two as being shutdown. Why is this happening ? Given this, seems the only way to start the two VMs which are down is in the GUI and not with virsh start domain which seems limiting. Any ideads would be greatly appreciated. [root@MBGVRT3323 ~]# virsh version Please enter your authentication name: root Please enter your password: Compiled against library: libvirt 5.7.0 Using library: libvirt 5.7.0 Using API: QEMU 5.7.0 Running hypervisor: QEMU 4.2.1 You have new mail in /var/spool/mail/root [root@MBGVRT3323 ~]#

Hi, Any idea how the appropriate step for upgrading cluster compatibility level ? We have two nodes that already up to date (already do yum upgrade manually and make sure its up to date), whenever we try to use Upgrade function in cluster, nothing changes. Thanks before.
