[one-users] mkswap operation failed

[Dmitri Chebotarov]

Hi

I'm running ONE 4.2. 
Hosts are CentOS 6.5 /w selinux enabled. 

Few VMs are using SWAP disk, ie. DISK=[SIZE="2048",TYPE="swap",DEV_PREFIX="vd",FORMAT="raw"].
For those VMs I get the error when trying deploy:
(it works OK with selinux=disabled)

I ran the same commands manually on the same host and get the same error, but swap created OK anyway:

[oneadmin at BC2-3 ~]$ dd if=/dev/zero of=/var/lib/one/datastores/111/delete.swap bs=1 count=1 seek=2048M

[oneadmin at BC2-3 ~]$ mkswap -L swap /var/lib/one/datastores/111/delete.swap

Looks like the message about "unable to relabel" is a warning, not error, and it would be OK to continue boot process for the VM.
