Description Rafael Majano 2014-07-21 15:28:39 UTC
Description of problem:
it happens when i start a kvm virtual machine
SELinux is preventing /usr/bin/qemu-system-x86_64 from 'read' accesses on the directory .

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that qemu-system-x86_64 should be allowed read access on the  directory by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep qemu-system-x86 /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Oops. Wrong bug number.

Comment 2 Miroslav Grepl 2014-07-31 18:48:36 UTC
What is "compartido"?.

Comment 3 Daniel Walsh 2014-08-06 22:42:41 UTC
If you change the label to svirt_home_t, it should be allowed to use it.


libvirt should really be changing the label on it.

Comment 4 Cole Robinson 2014-09-08 13:02:48 UTC
rafael, can you post your VM config? sudo virsh dumpxml $vmname
