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
virt-manager should show disk info for guest with disk type volume

Version:
virt-v2v-1.27.53-1.1.el7.x86_64
libguestfs-1.27.53-1.1.el7.x86_64

libvirt-1.2.8-3.el7.x86_64
virt-manager-0.10.0-20.el7.noarch - Due to bug 1138372 causes latest virt-manager GUI shows abnormal,I use this version of virt-manager.


How reproducible:
100%

Steps to Reproduce:
1.On rhel7,libvirt/qemu-kvm have support for disk type volume,prepare a guest with disk type volume.
# virsh dumpxml rhel6.6-tzheng
    <disk type='volume' device='disk'>
      <driver name='qemu' type='raw' cache='none'/>
      <source pool='default' volume='rhel6.6.img'/>
      <backingStore/>
      <target dev='vda' bus='virtio'/>
      <alias name='virtio-disk0'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x08' function='0x0'/>
    </disk>

2.Launch virt-manager,click the guest,open->show virtual hardware details->disk.
There is nothing shows in "Source path" and "Storage size",refer to the sreenshot.

Actual results：
There is nothing shows in "Source path" and "Storage size" from virt-manager GUI for guest with disk type volume.

Expected results:
"Source path" and "Storage size" show correctly from virt-manager GUI.

Comment 6 zhoujunqin 2014-10-09 07:20:17 UTC 
Try to verify with new build:
virt-manager-1.1.0-4.el7.noarch

steps:
1. Prepare a guest with disk type volume.
# virsh dumpxml rhel6.5-2
...
    <disk type='volume' device='disk'>
      <driver name='qemu' type='qcow2'/>
      <source pool='default' volume='juzhou-rhel6.img'/>
      <target dev='vda' bus='virtio'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x07' function='0x0'/>
    </disk>

2.Launch virt-manager,click the guest,open->show virtual hardware details->disk.
Check items "Source path" and "Storage size" showing:
（Details see Screenshot-2）

3. Try to delete guest rhel6.5-2 via virt-manager.
（Details see Screenshot-3）
Choose delete img file together (Details see Screenshot-4)

Result: Guest can be deleted with no error, but img file always existing.

# ls /var/lib/libvirt/images/juzhou-rhel6.img
/var/lib/libvirt/images/juzhou-rhel6.img

I think img file should be deleted and there is something wrong with "Source path", please help check and move this bug from ON_QA to ASSIGNED.

Comment 10 Giuseppe Scrivano 2014-10-09 07:34:27 UTC 
I don't think the img file should be deleted as I see the manually configured storage pool like just a reference to a volume  It seems correct to me to delete just the reference (by undefining the VM) instead of removing also the volume that is pointed to.

From virt-manager GUI,we can choose whether delete the img file or not.For this kind of disk,if we choose delete img file when delete guest,the image is still there.BTW,we can use 
virsh undefine $guest --remove-all-storage to undefine and delete this kind of guest.

# virsh undefine vm1 --remove-all-storage
Domain vm1 has been undefined
Volume 'hda'(sdl-test-sda) removed.
Comment 14 zhoujunqin 2014-11-03 08:40:06 UTC 
Try to verify this issue with new build:
virt-manager-1.1.0-5.el7.noarch

steps:
1. Prepare a guest with disk type volume.
# virsh dumpxml test-rhel6-second  |grep -A6 disk
    <disk type='volume' device='disk'>
      <driver name='qemu' type='raw' cache='none'/>
      <source pool='default' volume='test-rhel6-second-sda'/>
      <target dev='vda' bus='virtio'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/>
    </disk>
    <disk type='file' device='cdrom'>
      <driver name='qemu' type='raw'/>
      <target dev='hda' bus='ide'/>
      <readonly/>
      <address type='drive' controller='0' bus='0' target='0' unit='0'/>
    </disk>

2.Launch virt-manager,click the guest,open->show virtual hardware details->disk.
Check items "Source path" and "Storage size" showing:
Source path: test-rhel6-second-sda
Storage size: 8.00GiB

3. Try to delete guest test-rhel6-second via virt-manager.

Result: Guest can be deleted with no error, and img file deleted together.
# ls /var/lib/libvirt/images/test-rhel6-second-sda
ls: cannot access /var/lib/libvirt/images/test-rhel6-second-sda: No such file or directory

Seen above steps and Comment 10 and Comment 11, move this bug from ON_QA to VERIFIED.
