The VM Generation ID is a mechanism to provide a unique 128-bit, cryptographically random, and integer value identifier known as the GUID (Globally Unique Identifier) to the guest OS. The value is used to help notify the guest operating system when the virtual machine is executed with a different configuration. This patch adds support for a new "genid" XML element similar to the "uuid" element. The "genid" element can have two forms "<genid/>" or "<genid>$GUID</genid>". If the $GUID is not provided, libvirt will generate one and save it in the XML. Since adding support for a generated GUID (or UUID like) value to be displayed modifying the xml2xml test to include virrandommock.so is necessary since it will generate a "known" value.

Before we generate the command line for qemu, if the domain about to be launched desires to utilize the VM Generation ID functionality, then handle both the regenerating the GUID value for backup recovery (restore operation) and the startup after snapshot as both require a new GUID to be generated to allow the guest operating system to recognize the VM is re-executing something that has already executed before.

Still moving it has implications on the entire logic. Essentially it's a "common" place before we generate the command line to make sure if GenID is desired/wanted that we have the capability and then can if we need to for this path change the genid value. That need is based on starting the domain after specific events - there is a list in the spec: http://go.microsoft.com/fwlink/?LinkId=260709 and you'd have to read the replies from the v2 review series: https://www.redhat.com/archives/libvir-list/2018-April/msg02234.html in particular lots of discussion in patch 6 Right, strange - that got chopped off somewhere either during a rebase or cut-paste-copy from a previous review... I even posted/pushed the patch that changed all of them to use the < 0 syntax. Fixed this. That was the whole point of adding the flag - only a handful of explicit paths require changing the vmgen id. Those are controlled by calls to qemuProcessStart which eventually calls ProcessLaunch where we not only check the capability but the flag in order to force a change to the GenID based on whether we're in a path that requires a change.

https://bugzilla.redhat.com/show_bug.cgi?id=1149445 If the domain requests usage of the genid functionality, then add the QEMU '-device vmgenid' to the command line providing either the supplied or generated GUID value. Add tests for both a generated and supplied GUID value.

On 05/25/2018 04:24 AM, Michal Privoznik wrote: Which path would do that? I believe I'm making "interesting" use of the DO_TEST_CAPS_LATEST actually. There are two ways to call qemuBuildCommandLine - one via the PretendCmd logic and one via the Launch logic. In the Launch logic prior to calling qemuBuildCommandLine, the capability is checked *and* the "need" for generating a new GUID is determined. It was a "design decision" to not check/change it earlier. Is there somewhere else you believe that code should go? IDC, I can move it, but understand the risk of doing so. Now that we have DO_TEST_CAPS_LATEST there's no need to pass an explicit flag for the PretendCmd line logic, so we get it for free for the test/fake command line. John
