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.

2. prepare guest xml
# cat toy.xml
<domain type='lxc'>

3. start the guest
# virsh -c lxc:///
Welcome to virsh, the virtualization interactive terminal.

Type:  'help' for help with commands
       'quit' to quit

virsh # define toy.xml
Domain vm1 defined from toy.xml

virsh # list --all
 Id Name                 State
----------------------------------
  - vm1                  shut off

virsh # start vm1
error: Failed to start domain vm1

2. It does not exist in libvirt-0.9.3-8.el6 and libvirt-0.9.3-7.el6. So it is a regression. Also this bug will block most lxc testing.

Test in libvirt-0.9.3-7.el6:

virsh # start vm1
Domain vm1 started

virsh # exit

# virsh -c lxc:/// console vm1
Connected to domain vm1
Escape character is ^]
sh-4.1# ls
bin        dev   images  lost+found  mnt  proc  selinux  tmp
boot        etc   lib     media          net  root  srv      usr
cgroup        home  lib64   misc          opt  sbin  sys      var
sh-4.1# exit
exit
Comment 2 Daniel Veillard 2011-08-08 07:30:12 UTC 
Please test with libvirt-0.9.4-1.el6, not the old 0.9.3 builds and report,

thanks,

Daniel
Comment 3 Daniel Veillard 2011-08-08 07:34:13 UTC 
ah, got confused, it was with 0.9.4, okay
