RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Xianghua Chen 2020-07-03 13:13:50 UTC 
Description of problem: 
There should be a notification when trying to delete a transient VM

Version-Release number of selected component (if applicable):
cockpit-machines-222.1-1.el8.noarch
libvirt-dbus-1.3.0-2.module+el8.3.0+6423+e4cb6418.x86_64

How reproducible:
100%

Steps to Reproduce:
1. Prepare a image under /var/lib/libvirt/images/cirros.qcow2, and create a transient VM by :
# virsh create CirrOS.xml
The content of the xml:
<domain type='kvm'>
  <name>CirrOS</name>
  <memory unit='KiB'>1048576</memory>
  <currentMemory unit='KiB'>1048576</currentMemory>
  <vcpu placement='static'>2</vcpu>
  <os>
    <type arch='x86_64'>hvm</type>
    <boot dev='hd'/>
  </os>
  <features>
    <acpi/>
    <apic/>
    <vmport state='off'/>
  </features>
  <devices>
    <emulator>/usr/libexec/qemu-kvm</emulator>
    <disk type='file' device='disk'>
      <driver name='qemu' type='qcow2'/>
      <source file='/var/lib/libvirt/images/cirros.qcow2' index='1'/>
      <target dev='vda' bus='virtio'/>
    </disk>
    <interface type='network'>
      <source network='default' bridge='virbr0'/>
    </interface>
    <graphics type='vnc' port='5901' autoport='yes' listen='127.0.0.1'>
      <listen type='address' address='127.0.0.1'/>
    </graphics>
  </devices>
</domain>

2. Move mouse to the 'Delete' button 

Actual results:
In step 2, there is no notification like "This VM is transient. Shut it down if you wish to delete it."

Expected results:
In step 2, it's disabled and there should be a notification like "This VM is transient. Shut it down if you wish to delete it."

This sounds very similar to bug 1708193 (but that was for RHEL 7). Katerina already tried to fix this in https://github.com/cockpit-project/cockpit/pull/11785 but it got stuck. Need to dust this off and see what's still broken.

Hi Martin,
I've downgrade to 221.1-1 to double confirm, the problem has got fixed in 221, but the notification got missed on 222.
May be due to the interface change and not the same root cause to bug 1708193.
Comment 3 Martin Pitt 2020-07-06 05:24:23 UTC 
Ack, thanks Xianghua, so that's independent. Marking as regression and targetting at 8.3.0 then.
Comment 4 Katerina Koukiou 2020-07-22 09:50:14 UTC 
PR landed - https://github.com/cockpit-project/cockpit/pull/14381, will be in 224.

erified with package:
cockpit-machines-224-1.el8.noarch

Step:
1. Prepare a image under /var/lib/libvirt/images/cirros.qcow2, and create a transient VM by :
# virsh create CirrOS.xml
The content of the xml:
<domain type='kvm'>
  <name>CirrOS</name>
  <memory unit='KiB'>1048576</memory>
  <currentMemory unit='KiB'>1048576</currentMemory>
  <vcpu placement='static'>2</vcpu>
  <os>
    <type arch='x86_64'>hvm</type>
    <boot dev='hd'/>
  </os>
  <features>
    <acpi/>
    <apic/>
    <vmport state='off'/>
  </features>
  <devices>
    <emulator>/usr/libexec/qemu-kvm</emulator>
    <disk type='file' device='disk'>
      <driver name='qemu' type='qcow2'/>
      <source file='/var/lib/libvirt/images/cirros.qcow2' index='1'/>
      <target dev='vda' bus='virtio'/>
    </disk>
    <interface type='network'>
      <source network='default' bridge='virbr0'/>
    </interface>
    <graphics type='vnc' port='5901' autoport='yes' listen='127.0.0.1'>
      <listen type='address' address='127.0.0.1'/>
    </graphics>
  </devices>
</domain>

2. Move mouse to the 'Delete' button 

In step 2, it's disabled and there is a notification like "This VM is transient. Shut it down if you wish to delete it."
So verified
