[PATCH v2] network: add modify-or-add feature to net-update
by Abhiram Tilak
The current way of updating a network configuration uses `virsh
net-update` to add, delete or modify entries. But with such a mechansim
one should know if an entry with current info already exists. Adding
modify-or-add option automatically performs either modify or add
depending on the current state.

Changes in v2:
- Removed the modify-or-add functionality for sections
where modify is not applicable.
- Changed the existing implementation of `UpdateIPDHCPHost`,
to avoid code duplication.
- Changed the implementation of modify-or-delete to reassign
the `command` variable instead of using multiple nested conditions.

where modify is not applicable.
- Changed the existing implementation of `UpdateIPDHCPHost`,

[PATCH] Сheck snapshot disk is not NULL when searching it in the VM config
by Fima Shevrin
When creating a snapshot of a VM with multiple hard disks,
the snapshot takes into account the presence of all disks
in the system. If, over time, one of the disks is deleted,
the snapshot will continue to store knowledge of the deleted disk.
This results in the fact that at the moment of deleting the snapshot,
at the validation stage, a disk from the snapshot will be searched which
is not in the VM configuration. As a result, vmdisk variable will
be equal to NULL. Dereferencing a null pointer at the time of calling
virStorageSourceIsSameLocation(vmdisk->src, disk->src) will result in SIGSEGV.

[PATCH] rpc: avoid leak of GSource in use for interrupting main loop
by Daniel P. Berrangé
We never release the reference on the GSource created for
interrupting the main loop, nor do we remove it from the
main context if our thread is woken up prior to the wakeup
callback firing.
This can result in a leak of GSource objects, along with an
ever growing list of GSources attached to the main context,
which will gradually slow down execution of the loop, as
several operations are O(N) for the number of attached GSource
objects.

[PATCH] qemu: fix qemu command for pci hostdevs and ramfb='off'
by Jonathon Jongsma
There was no test for this and we mistakenly used 'B' rather than 'T'
when constructing the json value for this parameter. Thus, a value of
'off' was VIR_TRISTATE_SWITCH_OFF=2, which was translated to a boolean
value of 'true'.
