These functions provide a simple one line method of learning if the current domain has a pci-root or pcie-root bus.

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.

Add the secret object so the 'passwordid=' can be added if the command line if there's a secret defined in/on the host for TCP chardev TLS objects. Preparation for the secret involves adding the secinfo to the char source device prior to command line processing. There are multiple possibilities for TCP chardev source backend usage. Add test for at least a serial chardev as an example.

Since TLS was introduced hostwide for libvirt 2.3.0 and a domain configurable haveTLS was implemented for libvirt 2.4.0, we have to modify the migratable XML for specific case where the 'tls' attribute is based on setting from qemu.conf. The "tlsFromConfig" is libvirt internal attribute and is stored only in status XML to ensure that when libvirtd is restarted this internal flag is not lost by the restart. That flag is used to decide whether we should put *tls* attribute to migratable XML or not. Signed-off-by: NPavel Hrdina <phrdina@redhat.com>

Add an optional "tls='yes|no'" attribute for a TCP chardev. For QEMU, this will allow for disabling the host config setting of the 'chardev_tls' for a domain chardev channel by setting the value to "no" or to attempt to use a host TLS environment when setting the value to "yes" when the host config 'chardev_tls' setting is disabled, but a TLS environment is configured via either the host config 'chardev_tls_x509_cert_dir' or 'default_tls_x509_cert_dir' Signed-off-by: NJohn Ferlan <jferlan@redhat.com> Signed-off-by: NPavel Hrdina <phrdina@redhat.com>

Modeled after the qemuDomainHostdevPrivatePtr (commit id '27726d8c'), create a privateData pointer in the _virDomainChardevDef to allow storage of private data for a hypervisor in order to at least temporarily store secret data for usage during qemuBuildCommandLine.

This breaks vCPU hotplug, because when starting a domain, we create a copy of domain definition (which becomes live XML) and during the post parse callbacks we might adjust some tunings so that vCPU hotplug is possible. This reverts commit 581b7756.

We can't rely on def->emulator path. It may be provided by user as we give them opportunity to provide their own XML for migration. Therefore the path may point to just whatever binary (or even to a non-existent file). Moreover, this path is meant for destination, but the capabilities lookup is done on source. What we can do is to assume same capabilities for post parse callbacks as the running domain has. They will be used just to add some default models/controllers/devices/... anyway.

Storing the updated CPU definition in the live domain definition saves us from having to update it over and over when we need it. Not to mention that we will soon further update the CPU definition according to QEMU once it's started. A highly wanted side effect of this patch, libvirt will pass all CPU features explicitly specified in domain XML to QEMU, even those that are already included in the host model. This patch should fix the following bugs: https://bugzilla.redhat.com/show_bug.cgi?id=1207095 https://bugzilla.redhat.com/show_bug.cgi?id=1339680 https://bugzilla.redhat.com/show_bug.cgi?id=1371039 https://bugzilla.redhat.com/show_bug.cgi?id=1373849 https://bugzilla.redhat.com/show_bug.cgi?id=1375524 https://bugzilla.redhat.com/show_bug.cgi?id=1377913Signed-off-by: NJiri Denemark <jdenemar@redhat.com>

When migration fails, we need to poke QEMU monitor to check for a reason of the failure. We did this using query-migrate QMP command, which is not supposed to return any meaningful result on the destination side. Thus if the monitor was still functional when we detected the migration failure, parsing the answer from query-migrate always failed with the following error message: "info migration reply was missing return status" This irrelevant message was then used as the reason for the migration failure replacing any message we might have had. Let's use harmless query-status for poking the monitor to make sure we only get an error if the monitor connection is broken. https://bugzilla.redhat.com/show_bug.cgi?id=1374613Signed-off-by: NJiri Denemark <jdenemar@redhat.com>

Since the domain lock is not held during preparation of an external XML config, it is possible that the value can change resulting in unexpected failures during ABI consistency checking for some save and migrate operations. This patch adds a new flag to skip the checking of the cur_balloon value and then sets the destination value to the source value to ensure subsequent checks without the skip flag will succeed. This way it is protected from forges and is keeped up to date too. Signed-off-by: NNikolay Shirokovskiy <nshirokovskiy@virtuozzo.com>

Add support for using the new approach to hotplug vcpus using device_add during startup of qemu to allow sparse vcpu topologies. There are a few limitations imposed by qemu on the supported configuration: - vcpu0 needs to be always present and not hotpluggable - non-hotpluggable cpus need to be ordered at the beginning - order of the vcpus needs to be unique for every single hotpluggable entity Qemu also doesn't really allow to query the information necessary to start a VM with the vcpus directly on the commandline. Fortunately they can be hotplugged during startup. The new hotplug code uses the following approach: - non-hotpluggable vcpus are counted and put to the -smp option - qemu is started - qemu is queried for the necessary information - the configuration is checked - the hotpluggable vcpus are hotplugged - vcpus are started This patch adds a lot of checking code and enables the support to specify the individual vcpu element with qemu.

The vcpu order information is extracted only for hotpluggable entities, while vcpu definitions belonging to the same hotpluggable entity need to all share the order information. We also can't overwrite it right away in the vcpu info detection code as the order is necessary to add the hotpluggable vcpus enabled on boot in the correct order. The helper will store the order information in places where we are certain that it's necessary.

Individual vCPU hotplug requires us to track the state of any vCPU. To allow this add the following XML: <domain> ... <vcpu current='2'>3</vcpu> <vcpus> <vcpu id='0' enabled='yes' hotpluggable='no' order='1'/> <vcpu id='1' enabled='yes' hotpluggable='yes' order='2'/> <vcpu id='1' enabled='no' hotpluggable='yes'/> </vcpus> ... The 'enabled' attribute allows to control the state of the vcpu. 'hotpluggable' controls whether given vcpu can be hotplugged and 'order' allows to specify the order to add the vcpus.

Now that the monitor code gathers all the data we can extract it to relevant places either in the definition or the private data of a vcpu. As only thread id is broken for TCG guests we may extract the rest of the data and just skip assigning of the thread id. In case where qemu would allow cpu hotplug in TCG mode this will make it work eventually.
