commit 3a9b2b900c5dac18c9c48c40ec2dbeaa7c306a0e
Author: Jim Fehlig <jfehlig@novell.com>
Date: Wed Jan 13 18:54:58 2010 -0700
Modify virsh commands
Change all virsh commands that invoke virDomain{Attach,Detach}Device()
to use virDomain{Attach,Detach}DeviceFlags() instead.
Add a "--persistent" flag to these virsh commands, allowing user to
specify that the domain persisted config be modified as well.
V2: Only invoke virDomain{Attach,Detach}DeviceFlags() if
"--persistent" flag is specified. Otherwise invoke
virDomain{Attach,Detach}Device() to retain current behavior.
