Description Ole Sandum 2008-07-03 11:50:44 UTC
Description of problem:
> SELinux is preventing qemu-kvm (qemu_t) "getattr" to
/dev/mapper/Volumes-OldWindowsBackup (fixed_disk_device_t). 

Version-Release number:
3.3.1-72.fc9

Steps to Reproduce:
1. create a fresh LVM volume and initialize it with some file system
2. add its device file (in /dev/mapper/...) to a QEMU virtual machine as a
storage device (type 'Normal Disk Partition')
3. try to start that virtual machine
  
Actual results:
SELinux denies access as mentioned above. Virtual machine cannot start.

Comment 1 Daniel Walsh 2008-07-03 15:26:39 UTC
In order to get SELinux to work with qemu, you need to make sure this disk is
labeled correctly.

# semanage fcontext -a -t virt_image_t /dev/mapper/Volumes-OldWindowsBackup
# restorecon /dev/mapper/Volumes-OldWindowsBackup

Should allow you to run in enforcingm mode.

Hopefully virtmanager will start doing this automatically.
