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 2021-12-21 04:22:27 UTC 
Description of problem:
[Machines] The Bus is changed from virtio to ide after changing device type on Custom Path

Version-Release number of selected components (if applicable):
cockpit-machines-256-1.el9.noarch
cockpit-258-1.el9.x86_64
libvirt-dbus-1.4.1-5.el9.x86_64

How reproducible:
100%

Steps to Reproduce:
1. Prepare a running vm, like cirros. Choose "Alpine Linux 3.10" when importing, you will find the Bus is ide on Disks tab.

2. Prepare a fake image  like:

# touch /tmp/fake.img

3. Click "Add disk", choose "Custom path"

4. Import Custom path: /tmp/fake.img

Expand "Show additional options", you will find Bus type is virtio

5. Change device to "CD/DVD disc" then change back to "Disk image file"

The Bus type is changed to "ide"

And if click Add now, you will get an error expected for ide type like 

"internal error: unable to execute QEMU command 'device_add': Bus 'ide.1' does not support hotplugging"


Actual results:
As shown in step 5. 


Expected results:
Is it possible to avoid changing to ide downstream in such scenario as it's not supported?
This is a tiny user experience issue and normally don't have high risk, just raise here in case we have better solution, but feel free to leave comments for any thoughts here.

Additional info:
Same problem on RHEL8&RHEL9.
Comment 1 Simon Kobyda 2023-04-04 14:30:11 UTC 
Cannot reproduce locally. It is likely that it was https://github.com/cockpit-project/cockpit-machines/pull/646 fixed since cokpit-machines-279

Can you confirm that on cokpit-machines-279 and newer the bug is no longer present?

Yes, I've tried with cockpit-machines-286-1.el9.noarch on RHEL9 , the problem is resolved now.
And as there is no 279 on RHEL, I tried cockpit-machines-279-1.fc37.noarch on FEDORA37, it's fixed too.
Comment 6 Xianghua Chen 2023-06-07 06:47:55 UTC 
Verified with packages:
cockpit-machines-291-1.el9.noarch
cockpit-292-1.el9.x86_64
libvirt-dbus-1.4.1-5.el9.x86_64
libvirt-client-9.3.0-2.el9.x86_64

Steps:
1. Prepare a running vm, like cirros. Choose "Alpine Linux 3.17" when importing, the Bus is virtio on Disks tab.

2. Prepare a fake image  like:
# touch /tmp/fake.img

3. Click "Add disk", choose "Custom path"

4. Import Custom path: /tmp/fake.img
Expand "Show additional options", you will find Bus type is virtio

5. Change device to "CD/DVD disc" then change back to "Disk image file"
The Bus type is changed to "scsi" first then back to "virtio"

6. Click Add now, the disk can be added sucessfully.

So verified.
