[Kimchi-devel] [PATCH 2/3] Github bug #327: NFS pool workaround: timeout adjustments

[Daniel Barboza]

From: Daniel Henrique Barboza <danielhb at linux.vnet.ibm.com>

Adding a smaller timeout in the 'prepare()' method of
libvirtstoragepool ('mount' and 'umount' commands).

Fixing an error in utils/run_command() that prevented the
TimeoutExpired exception to be raised sometimes.
