Add a new disk "driver" attribute "iothread" to be parsed as the thread number for the disk to use. In order to more easily facilitate the usage and configuration of the iothread, a "zero" for the attribute indicates iothreads are not supported for the device and a positive value indicates the specific thread to try and use.

Add a new capability to ensure the iothreads feature exists for the qemu emulator being run - requires the "query-iothreads" QMP command. Using the domain XML add correspoding command argument in order to generate the threads. The iothreads will use a name space "iothread#" where, the future patch to add support for using an iothread to a disk definition to merely define which of the available threads to use. Add tests to ensure the xml/argv processing is correct. Note that no change was made to qemuargv2xmltest.c as processing the -object element would require knowing more than just iothreads.

Introduce XML to allowing adding iothreads to the domain. These can be used by virtio-blk-pci devices in order to assign a specific thread to handle the workload for the device. The iothreads are the official implementation of the virtio-blk Data Plane that's been in tech preview for QEMU.

Coverity noted that all callers to libxlDomainEventQueue() could ensure the second parameter (event) was true before calling except this case. As I look at the code and how events are used - it seems that prior to generating an event for the dom == NULL condition, the resume/suspend event should be queue'd after the virDomainSaveStatus() call which will goto cleanup and queue the saved event anyway.

Implement the API function for virDomainListGetStats and virConnectGetAllDomainStats in a modular way and implement the VIR_DOMAIN_STATS_STATE group of statistics. Although it may look like the function looks universal I'd rather not expose it to other drivers as the coming stats groups are likely to do qemu specific stuff to obtain the stats.

One useless warning, but the other one rather pertinent. On entry the 'trans' variable is initialized to VIR_DOMAIN_DISK_TRANS_DEFAULT. When the "trans" was found in the parsing loop it def->geometry.trans was assigned to the return from virDomainDiskGeometryTransTypeFromString and then 'trans' was used to do the comparison to see if it was valid. So remove 'trans' and use def->geometry.trans properly

If there was a failure processing 'authdef' and the code went to cleanup before the setting to source->auth, then it'd be leaked.

In libxlDomainMigrationPrepare() if the uri_in is false, then 'hostname' is allocated and used "generically" in the routine, but not freed. Conversely, if uri_in is true, then a uri is allocated and hostname is set to the uri->hostname value and likewise generically used. At function exit, hostname wasn't free'd in the !uri_in path, so that was added. To just make it clearer on usage the else path became the call to virURIFree() although I suppose technically it didn't have to since it would be a call using (NULL)

Coverity determined that on error path that 'mach' wouldn't be free'd Since virCapabilitiesFreeGuestMachine() isn't globally available, we'll insert first and then if the VIR_STRDUP's fail they it will eventually cause the 'mach' to be freed in the error path

Coverity found that on error paths, the 'arg' value wasn't be cleaned up. Followed the example in qemuAgentSetVCPUs() where upon successful call to qemuAgentCommand() the 'cpus' is set to NULL; otherwise, when cleanup occurs the free the memory for 'arg'

In each of these cases, Coverity complains that the result count returned on error paths would be -1 disregarding that the count and the corresponding are "linked" together (it doesn't know that). Simple enough to check and remove the warning

Add "domstats" command that excercises both of the new APIs depending if you specify a domain list or not. The output is printed as a key=value list of the returned parameters.

In function virQEMUCapsParseMachineTypesStr, VIR_STRNDUP allocates memory for 'name' in {do,while} loop. If 'name' isn't freed before 'continue', its memory will be allocated again in the next loop. In this case the memory allocated for 'name' in privious loop is useless and not freed. Free it before continue this loop to fix that. Signed-off-by: NWang Rui <moon.wangrui@huawei.com>

The call to virDomainSnapshotRedefinePrep() had a spurrious ! in front of it which caused Coverity to complan that the expression is always false.

Coverity complains that checking for domain->def being non NULL in the if (live) path of virDomainObjAssignDef() would be unnecessary or a NULL deref since the call to virDomainObjIsActive() would already dereference domain->def when checking if the def->id field was != -1. Checked all callers to virDomainObjAssignDef() and each at some point dereferences (vm)->def->{field} prior to calling when live is true.

In qemuNetworkIfaceConnect() a call to virNetDevBandwidthSet() is made where the function prototype requires the first parameter (net->ifname) to be non NULL. Coverity complains that the subsequent non NULL check for net->ifname prior to the next call gets flagged as an unnecessary check. Resolve by removing the extra check

In virDomainActualNetDefFormat() a call to virDomainNetGetActualType(def) was made before a check for (!def) a few lines later. This triggered Coverity to note the possible NULL deref. Just moving the initialization to after the !def checks resolves the issue

There were two occurrances of attempting to initialize actualType by calling virStorageSourceGetActualType(src) prior to a check if (!src) resulting in Coverity complaining about the possible NULL dereference in virStorageSourceGetActualType() of src. Resolve by moving the actualType setting until after checking !src

If virDomainDiskDefFree(disk) is called in 'skipdisk:', then it's possible to either return to skipdisk without reallocating a new disk (via the if condition just prior) or to end the loop having deleted the disk. Since virDomainDiskDefFree() does not pass by reference, disk isn't changed in this context, thus the possible issue.

There were two warnings in this module If the VIR_ALLOC_N(def->serials, 1) fails, then a virDomainChrDefFree(chr) is called and we jump to cleanup which makes the same call. Just remove the one after VIR_ALLOC_N() In the label "skipnic:" a virDomainNetDefFree(net) is made; however, if in going back to the top of the loop we jump back down to skipnic for any reason, the call will attempt to free an already freed structure since "net" was not passed by reference to virDomainNetDefFree(). Just set net = NULL in skipnic: to resolve the issue.

Coverity complains that calling virNetworkDefFree(def), then jumping to the cleanup: label which calls virNetworkDefFree(def) could result in a double_free. Just remove the call from the if statement.
