Coverity identified that this variable might be leaked. And it's right. If an error occurred and we have to roll back the control jumps to try_remove label where we save the current error (see 0e82fa4c for more info). However, inside the code a jump onto other label is possible thus leaking the error object. Signed-off-by: NMichal Privoznik <mprivozn@redhat.com>

The memory device alias needs to be treated as machine ABI as qemu is using it in the migration stream for section labels. To simplify this generate the alias from the slot number unless an existing broken configuration is detected. With this patch the aliases are predictable and even certain configurations which would not be migratable previously are fixed. Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1359135

As with other devices assign the slot number right away when adding the device. This will make the slot numbers static as we do with other addressing elements and it will ultimately simplify allocation of the alias in a static way which does not break with qemu.

由 Peter Krempa 提交于
Detect on reconnect to a running qemu VM whether the alias of a hotpluggable memory device (dimm) does not match the dimm slot number where it's connected to. This is necessary as qemu is actually considering the alias as machine ABI used to connect the backend object to the dimm device. This will require us to keep them consistent so that we can reliably restore them on migration. In some situations it was currently possible to create a mismatched configuration and qemu would refuse to restore the migration stream. To avoid breaking existing VMs we'll need to keep the old algorithm though.
-
由 Peter Krempa 提交于
Simplify handling of the 'dimm' address element by allowing to specify the slot number only. This will allow libvirt to allocate slot numbers before starting qemu.

This helps in selecting log level of the gluster gfapi, output to stderr. The option is 'gluster_debug_level', can be tuned by editing '/etc/libvirt/qemu.conf' Debug levels ranges 0-9, with 9 being the most verbose, and 0 representing no debugging output. The default is the same as it was before, which is a level of 4. The current logging levels defined in the gluster gfapi are: 0 - None 1 - Emergency 2 - Alert 3 - Critical 4 - Error 5 - Warning 6 - Notice 7 - Info 8 - Debug 9 - Trace Signed-off-by: NPrasanna Kumar Kalever <prasanna.kalever@redhat.com> Signed-off-by: NPeter Krempa <pkrempa@redhat.com>

Allow detecting capabilities according to the qemu QMP schema. This is necessary as sometimes the availability of certain options depends on the presence of a field in the schema. This patch adds support for loading the QMP schema when detecting qemu capabilities and adds a very simple query language to allow traversing the schema and selecting a certain element from it. The infrastructure in this patch uses a query path to set a specific capability flag according to the availability of the given element in the schema.
-
由 Peter Krempa 提交于
Call 'query-qmp-schema' and store the returned types in a hash table keyed by the 'name' field so that the capabilities code can traverse it.

We're keeping some things at default and that's not something we want to do intentionally. Let's save some sensible defaults upfront in order to avoid having problems later. The details for the defaults (of the newer implementation) can be found in qemu's commit 5400c02b90bb: http://git.qemu.org/?p=qemu.git;a=commit;h=5400c02b90bb Since we are merely saving the defaults it will not change the guest ABI and thanks to the fact that we're doing it in the PostParse callback it will not break the ABI stability checks.

Support for virtio disks was added in commit id 'fceeeda2', but not for SCSI drives. Add the secret for the server when hotplugging a SCSI drive. No need to make any adjustments for unplug since that's handled during the qemuDomainDetachDiskDevice call to qemuDomainRemoveDiskDevice in the qemuDomainDetachDeviceDiskLive switch. Added a test to/for the command line processing to show the command line options when adding a SCSI drive for the guest.
