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 Mikolaj Kucharski 2010-05-20 23:41:38 UTC 
After fresh installation of RHEL6 beta with qemu-kvm, libvirt and python-virtinst first run of virt-install failed:


# virt-install \

Comment 3 Mikolaj Kucharski 2010-05-20 23:50:04 UTC 
After above `rpm --setperms' everything works fine. Reporting this as I don't
how that happened that permissions changed. I'm not aware that I've change
that.
Comment 4 Mikolaj Kucharski 2010-05-20 23:53:26 UTC 
I had exactly the same issue when I installed Fedora 12 with virt-preview for f12 (rawvirt) repository, so Fedora 13 may be affected as well.
Comment 5 Mikolaj Kucharski 2010-05-21 00:02:19 UTC 
# rpm -q libvirt python-virtinst redhat-release
libvirt-0.7.6-2.el6.x86_64
python-virtinst-0.500.1-3.el6.noarch
redhat-release-6-6.0.0.24.el6.x86_64
Comment 6 Mikolaj Kucharski 2010-05-25 14:15:01 UTC 
Maybe here is the source of the problem?

# virsh pool-dumpxml default | grep -w mode
      <mode>0700</mode>

but that should be 0711

# ls -lhd /var/lib/libvirt/images
drwx--x--x. 2 root root 4.0K May 21 10:45 /var/lib/libvirt/images
Comment 7 Cole Robinson 2010-05-25 14:42:18 UTC 
This is fixed by the libvirt package currently queued for RHEL6.
Comment 8 RHEL Program Management 2010-06-07 15:54:08 UTC 
This request was evaluated by Red Hat Product Management for inclusion in a Red
Hat Enterprise Linux major release.  Product Management has requested further
review of this request by Red Hat Engineering, for potential inclusion in a Red
Hat Enterprise Linux Major release.  This request is not yet committed for
inclusion.
Comment 11 LiZhang Li 2010-06-28 07:27:55 UTC 
Verified using the latest version of using the latest libvirt(libvirt-0.8.1-10.el6.x86_64), qemu(qemu-kvm-0.12.1.2-2.81.el6.x86_64) and python-virtinst(python-virtinst-0.500.3-2.el6.noarch).


The installation works fine.

virt-install \
         --connect qemu:///system \
         --name fedora_12_test \
         --ram 512 \
         --disk path=/var/lib/libvirt/images/fedora_12.img,size=4 \
         --cdrom /var/lib/libvirt/boot/Fedora-13-x86_64-DVD.iso \
         --network bridge=virbr0,model=e1000 \
         --vnc \
         --hvm \
         --accelerate \
         --os-variant fedora12
