Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.

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 Nan Zhang 2011-03-22 11:47:17 UTC

Description of problem:

Version-Release number of selected component (if applicable):
libvirt-0.8.7-13.el6.x86_64
python-virtinst-0.500.5-2.el6.noarch

How reproducible:
Always

Steps to Reproduce:
# virt-install -n test1 -r 512 -f /var/lib/libvirt/images/test1.img -s 6 -c /var/lib/libvirt/boot/Fedora-14-i686-Live-Desktop.iso --vnc --serial udp,host=127.0.0.1:2222

Actual results:

Comment 1 Cole Robinson 2011-03-22 20:38:08 UTC

Looks like a libvirt bug actually. Patch sent upstream:

https://www.redhat.com/archives/libvir-list/2011-March/msg01038.html

Comment 2 RHEL Program Management 2011-04-04 02:05:54 UTC

Since RHEL 6.1 External Beta has begun, and this bug remains
unresolved, it has been rejected as it is not proposed as
exception or blocker.

Red Hat invites you to ask your support representative to
propose this request, if appropriate and relevant, in the
next release of Red Hat Enterprise Linux.

Comment 3 Dave Allan 2011-06-10 03:23:49 UTC

DV, did this ever get committed?

Comment 4 Daniel Veillard 2011-08-10 07:17:46 UTC

No and we are still having the problem.
I changed the patch to address the comments, and posted the new version:

https://www.redhat.com/archives/libvir-list/2011-August/msg00335.html

Comment 7 zhpeng 2011-08-17 10:45:11 UTC

Hi,
I have reproduced the bug with :
libvirt-0.8.7-14.el6.x86_64
python-virtinst-0.500.5-3.el6.noarch

And i have verified on the latest version on:
python-virtinst-0.600.0-2.el6.noarch
libvirt-0.9.4-4.el6.x86_64

The steps are as follows:

1, download the iso # cd /var/lib/libvirt/boot # wget http://download.englab.nay.redhat.com/pub/fedora/linux/releases/14/Live/i686/Fedora-14-i686-Live-Desktop.iso
2, create a domain, and vnc-viewer popup, and the guest machine boot from fedora iso. 
# virt-install -n test1 -r 512 -f /var/lib/libvirt/images/test1.img -s 6 -c /var/lib/libvirt/boot/Fedora-14-i686-Live-Desktop.iso --vnc --serial udp,host=127.0.0.1:2222

Starting install...
Allocating 'test1.img' | 6.0 GB 00:00
Creating domain... | 0 B 00:00

3, close the vnc-viewer, Terminal shows:
Domain installation still in progress. You can reconnect to
the console to complete the installation process.

And now it's expected results. The test is pass.
