hi.
my environment: centos 6.3, qemu 1.5(source code build), libvirt
libvirt-0.10.2-18.el6_4.2.x86_64.selinux enforce .
i have 2 questions
1.snapshot. permisson deny.
dumpxml:
<seclabel type='dynamic' model='selinux' relabel='yes'>
<label>system_u:system_r:svirt_t:s0:c33,c172</label>
<imagelabel>system_u:object_r:svirt_image_t:s0:c33,c172</imagelabel>
</seclabel>
command line:
[root@ovirtdev images]# ls -lZ
-rw-r--r--. qemu qemu system_u:object_r:virt_image_t:s0 test.qcow2
image does not have the same MLS?
it does not seem like a selinux problem, because selinix does not record this
deny.
2.vnet problem
May 27 09:48:49 ovirtdev NetworkManager[2365]: <warn>
/sys/devices/virtual/net/vnet0: couldn't determine device driver; ignoring...
[root@ovirtdev images]# brctl show
bridge name bridge id STP enabled interfaces
ovirtmgmt 8000.000c290a2351 no eth0
vnet0
what is the reason? does it matter with libvirt?
thanks
