So, our mingw build is broken. It's because while libvirt_shell library is using some of our internal APIs, e.g. virStrndup, and readline API but it's not being linked with nor libvirt.la nor libreadline. Only subsequent users of the library, like virsh, do link to the needed libraries. In fact, I'm surprised Linux linker doesn't care, because how can it make a static library with missing symbols is mystery to me. Signed-off-by: NMichal Privoznik <mprivozn@redhat.com>

As of commit 69929941, we set graphics/@listen attribute according to the first listen child element even if that element is of type='network'. This was done for backward compatibility with applications which only support the original listen attribute. However, by doing so we broke migration to older libvirt which tried to check that the listen attribute matches one of the listen child elements but which did not take type='network' elements into account. We are not concerned about compatibility with old applications when formatting domain XML for migration for two reasons. The XML is consumed only by libvirtd and the IP address associated with type='network' listen address on the source host is just useless on the destination host. Thus, we can safely avoid propagating the type='network' IP address to graphics/@listen attribute when creating migratable XML. https://bugzilla.redhat.com/show_bug.cgi?id=1265111Signed-off-by: NJiri Denemark <jdenemar@redhat.com>

This seemed to be more of a false positive as for some reason Coverity was missing the "ret < 0" goto error condition and somehow believing that event could be overwritten. At first I thought it was just the ret != 0 condition difference, but it wasn't. In any case, make use of the recent change to qemuDomainEventQueue to check event == NULL and just pass it as a parameter directly in the error path. That avoids the error.

As it turns out, ret can only be 0 or -1, so rather than have some comparisons be "ret < 0" and others be "ret != 0", make them all "ret < 0".

Coverity complains that return from virHookCall is not checked in one place in qemuProcessStop. Since the comment notes that we cannot stop the operation even it if fails, just added the ignore_value.

https://bugzilla.redhat.com/show_bug.cgi?id=871452 So, you want to create a domain from XML. The domain already exists in libvirt's database of domains. It's okay, because name and UUID matches. However, on domain startup, internal representation of the domain is overwritten with your XML even though we claim that the XML you've provided is a transient one. The bug is to be found across nearly all the drivers. Le sigh. Signed-off-by: NMichal Privoznik <mprivozn@redhat.com>

https://bugzilla.redhat.com/show_bug.cgi?id=871452 Okay, so we allow users to 'virsh create' an already existing domain, providing completely different XML than the one stored in Libvirt. Well, as long as name and UUID matches. However, in some drivers the code that handles errors unconditionally removes the domain that failed to start even though the domain might have been persistent. Fortunately, the domain is removed just from the internal list of domains and the config file is kept around. Steps to reproduce: 1) virsh dumpxml $dom > /tmp/dom.xml 2) change XML so that it is still parse-able but won't boot, e.g. change guest agent path to /foo/bar 3) virsh create /tmp/dom.xml 4) virsh dumpxml $dom 5) Observe "No such domain" error Signed-off-by: NMichal Privoznik <mprivozn@redhat.com>

Now that virQEMUDriverCreateXMLConf is never called with NULL (after 086f37e9) we can safely drop useless check in qemuDomainDeviceDefPostParse as we are guaranteed to be always called with the driver initialized. Therefore checking if driver is NULL makes no sense. Moreover, if we mix it with direct driver dereference. And after that, we are sure that nor @cfg will be NULL, therefore we can drop checks for that too. Signed-off-by: NMichal Privoznik <mprivozn@redhat.com>

Although 0 length block jobs aren't entirely useful, the output of virsh blockjob is empty due to the condition that suppresses the output for migration jobs that did not start. Since the only place that actually uses the condition that suppresses the output is in migration, let's move the check there and thus add support for 0 of 0 equaling to 100%.

Qemu unfortunately doesn't update internal state right after migration and so the actual balloon size as returned by 'query-balloon' are invalid for a while after the CPUs are started after migration.

My original implementation was based on a qemu version that still did not have all the checks in place. Using sizes that would align to odd megabyte increments will produce the following error: qemu-kvm: -device pc-dimm,node=0,memdev=memdimm0,id=dimm0: backend memory size must be multiple of 0x200000 qemu-kvm: -device pc-dimm,node=0,memdev=memdimm0,id=dimm0: Device 'pc-dimm' could not be initialized Introduce an alignment retrieval function for memory devices and use it to align the devices separately and modify a test case to verify it.

Even though we hit an error in client's IO loop, we still want to process any pending data. So instead of reporting the error right away, we can finish the current iteration and report the error once we're done with it. Note that the error is stored in client->error by virNetClientMarkClose so we don't need to worry about it being reset or rewritten by any API we call in the meantime.

For some machine types ppc64 machines now require that memory sizes are aligned to 256MiB increments (due to the dynamically reconfigurable memory). As now we treat existing configs reasonably in regards to migration, we can round all the sizes unconditionally. The only drawback will be that the memory size of a VM can potentially increase by (256MiB - 1byte) * number_of_NUMA_nodes. Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1249006

When we are starting a qemu process for an incomming migration or snapshot reloading we should not modify the memory sizes in the domain since we could potentially change the guest ABI that was tediously checked before. Additionally the function now updates the initial memory size according to the NUMA node size, which should not happen if we are restoring state. Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1252685

由 Peter Krempa 提交于
When implementing memory hotplug I've opted to recalculate the initial memory size (contents of the <memory> element) as a sum of the sizes of NUMA nodes when NUMA was enabled. This was based on an assumption that qemu did not allow starting when the NUMA node size total didn't equal to the initial memory size. Unfortunately the check was introduced to qemu just lately. This patch uses the new XML parser flag to decide whether it's safe to update the memory size total from the NUMA cell sizes or not. As an additional improvement we now report an error in case when the size of hotplug memory would exceed the total memory size. The rest of the changes assures that the function is called with correct flags.

Add 'initial_memory' member to struct virDomainMemtune so that the memory size can be pre-calculated once instead of inferring it always again and again. Separating of the fields will also allow finer granularity of decisions in later patches where it will allow to keep the old initial memory value in cases where we are handling incomming migration from older versions that did not always update the size from NUMA as the code did previously. The change also requires modification of the qemu memory alignment function since at the point where we are modifying the size of NUMA nodes the total size needs to be recalculated too. The refactoring done in this patch also fixes a crash in the hyperv driver that did not properly initialize def->numa and thus virDomainNumaGetMemorySize(def->numa) crashed. In summary this patch should have no functional impact at this point.
