Looking at syslog I know see apparmor is denying mknod creation on the
directory :
Jan 4 14:41:21 minipc kernel: [127823.552343] audit: type=1400
audit(1420378881.315:171): apparmor="DENIED" operation="mknod" profile
="libvirt-73aa79f1-0023-4e37-8001-5be78e884348"
name="/var/lib/libvirt/qemu/channel/target/centostest.org.qemu.guest_agent.0"
pid=28480 comm="qemu-system-x86" requested_mask="c" denied_mask="c"
fsuid=116 ouid=116
So tu summarize :
- there are missing dirs
- there are missing rules for these dirs
** Summary changed:
- apparmor denied mknod creation in /var/lib/libvirt/qemu/channel/target
+ missing dirs /var/lib/libvirt/qemu/channel/target while creating centos 7 vm
