New subject: [libvirt] [PATCH v2 1/4] test_driver: introduce domain-private data
vm-specific data can be used by APIs that need to preserve some state
between calls
Some of them are:
- FS-related APIs for remembering which mountpoints are frozen
- virDomainSetTime / virDomainGetTime for maintaining time information
- virDomainSetIOThreadParams for storing the I/O thread parameters
- virDomainManagedSaveDefineXML for internally storing the VM definition

On success update the domain-private data. Consider / and /boot to be
the only mountpoints avaiable in order to be consistent with the other
FS-related calls.

we can simplify ^this hunk a bit by applying what patch 3/4 does, so I'll
squash the following in:
