Getting info about qemu guest agent into the engine
Hello, wise people! As a part of BZ1615830[1] I want to add information about qemu guest agent to engine's DB. I have some trouble figuring out some details. 1. VDSM seems to be using QGA, but it does not report any information about it. Am I right? I only found a mention about it in `xml` field in JSON returned by `VM.getInfo` (and `Host.getVMFullList`): a `virtio` channel as documented in libvirt. 2. How does the engine puts data into `vm_dynamic` table? I can't find any usage for `InsertVmDynamic` procedure. 3. Also, it's not clear to me how (whether?) the engine consumes output of VM.getInfo/Host.getVMFullList. Any pointers to relevant code appreciated.

what do you mean to report any information? There are guest agent reported fields which are either there or not One such field is appsList which returns the agent itself (well, it’s fake for qemu-ga, but the agent string is always put there)
I only found a mention about it in `xml` field in JSON returned by `VM.getInfo` (and `Host.getVMFullList`): a `virtio` channel as documented in libvirt.
virtio channels are always there for both agents

app_list
3. Also, it's not clear to me how (whether?) the engine consumes output of VM.getInfo/Host.getVMFullList.
it does not in 4.2+ clusters, see FullListAdapter::getVmFullList() HTH, michal
Any pointers to relevant code appreciated.

Oh, appsList, I didn't look into stats. Thanks, I guess that's what I was looking for.

oh sorry, I though you still talk about the guest agent info only VmDynamic::updateRuntimeData()

Look at VmsMonitoring::flush() method. The VmDynamic, VmStatistics and other fields are stored to the DB there.
