libvirt: qcow2/lvm backing image permissions are NOT changed to qemu:qemu
Last modified: 2010-07-08 14:18:10 EDT
When I attempt to create a new VM I get the following error : Unable to complete install '<class 'libvirt.libvirtError'> internal error unable to start guest: qemu: could not open disk image /var/lib/libvirt/images/Test.img: Permission denied Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/create.py", line 1435, in do_install dom = guest.start_install(False, meter = meter) File "/usr/lib/python2.6/site-packages/virtinst/Guest.py", line 660, in start_install return self._do_install(consolecb, meter, removeOld, wait) File "/usr/lib/python2.6/site-packages/virtinst/Guest.py", line 758, in _do_install self.domain = self.conn.createLinux(install_xml, 0) File "/usr/lib/python2.6/site-packages/libvirt.py", line 1077, in createLinux if ret is None:raise libvirtError('virDomainCreateLinux() failed', conn=self) libvirtError: internal error unable to start guest: qemu: could not open disk image /var/lib/libvirt/images/Test.img: Permission denied The image file Test.img was alredy created using a different image file as base using the following command qemu-img create -b CentOS.img -f qcow2 Test.img File permissions and SELinux Context seems appropriate # ls -Z Test.img -rw-------. root root system_u:object_r:virt_image_t:s0 Torrent.img The image loads without any problems from the command line as root using qemu Test.img
Hmm, I think there are known permission issues with libvirt security drivers and files with backing stores. Can you provide: ls -Z /var/lib/libvirt/images virsh pool-list /var/lib/libvirt/images virsh vol-dumpxml /var/lib/libvirt/images/Test.img Does 'setenforce 0' help? Re-assiging to libvirt.

This message is a reminder that Fedora 11 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 11. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '11'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 11's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 11 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
I marked the bug as concerning ver 11 of Fedora by mistake.
