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 zhe peng 2011-08-04 08:39:25 UTC 
Description of problem:
if save a guest,then can't delete the guest from virt-manager,and no error in debug info.

Version-Release number of selected component (if applicable):
virt-manager-0.9.0-5.el6.x86_64
libvirt-0.9.4-1.el6.x86_64


How reproducible:
always

Steps to Reproduce:
1.install a guest ,make sure the guest running
2.lunch virt-manager,click guest name to open guest graphics console
3.click "Virtual Machine"->"Shut Down"->"Save"
4.after save complete,the guest will shutoff,switch to virt-manager main page,and delete the guest

Actual results:
the guest still in virt-manager w/o any msg
output:
2011-08-04 04:08:57,898 (delete:159): Threading off connection to delete vol.
2011-08-04 04:08:57,899 (delete:173): Removing VM 'spice'

refer to bug: 697742 , libvirt have new options for this

Expected results:
the guest remove from virt-manager,or have dialog to prompt user


Additional info:
actually , when save a guest ,will have an error in debug info,seems another issue

Comment 1 Cole Robinson 2011-08-24 16:50:59 UTC 
Does virsh undefine have the same problem? I think I recall a similar libvirt issue, so reassigning there.
Comment 2 Eric Blake 2011-08-24 17:12:36 UTC 
Libvirt had a problem where it allowed deletion without removing the save file, and it was fixed in virsh at the series ending here:

commit 83e849c197caf09373d1ff7337d9e2b487ad905c
Author: Osier Yang <jyang>
Date:   Wed Jul 20 11:12:46 2011 +0800

    undefine: Extend virsh undefine to support the new flag
    
    If the domain has managed save image, and --managed-save is
    not specified, then it fails with an error telling the user
    that a managed save image still exists.

virt-manager needs to be taught the same logic as virsh.  It is unsafe to undefine a domain with managed save data, since stranding that managed save data would interfere with the creation of a new domain by the same name.  When managing older libvirt, virt-manager must manually check for managed save data first; when managing newer libvirt, virt-manager can use the new flag.

Reassigning to virt-manager - the change in libvirt was intentional to forbid undefining of domains with save data, so virt-manager need to make it easier to automatically remove the save data before undefining domains, and to provide the safety check that is guaranteed by newer libvirt but missing in older libvirt.

Comment 7 Huming Jiang 2011-09-09 03:37:58 UTC 
Reproduce with the following packages:
virt-manager-0.9.0-5.el6.x86_64
libvirt-0.9.4-9.el6.x86_64

Verified with the following packages:
virt-manager-0.9.0-6.el6.x86_64
libvirt-0.9.4-9.el6.x86_64
kernel-2.6.32-191.el6.x86_64
qemu-kvm-0.12.1.2-2.184.el6.x86_64
python-virtinst-0.600.0-3.el6.noarch

Steps:
1.lunch virt-manager,
#virt-manager --debug
2.install a guest ,make sure the guest running
3.click guest name to open guest graphics console
3.click "Virtual Machine"->"Shut Down"->"Save"
4.after save complete,the guest will shutoff,switch to virt-manager main
page,and delete the guest
 
The guest could be deleted.
So move the status of this bug from "ON_QA" to "Verified".
