Can you confirm? Also, the detection/handling is only fixed in vdsm since last Thu, not in any build (only the tag from today has it, or nightly) Can you confirm?+1 with Michal here - this should never happen in real life scenarios. The most important thing to notice in the log is this part: libvirtd doesn\\'t use systemd socket activation - one or more of its socket units have been masked As you rightly noticed in the other devel thread ("Task Start and enable services failed to execute"), libvirt's socket units are masked by libvirt itself in an upgrade scenario: - you have old libvirt and vdsm installed - vdsm configures libvirt to pass the "--listen" flag to the daemon - you upgrade libvirt and vdsm to a version that uses socket activation - libvirt installation scripts notice the "--listen" flag and respect it by disabling its own socket activation mechanism, which is done by masking sockets - new vdsm version is lost - it sees that there's a new libvirt version that uses socket activation (because the socket units are there), but they've been masked in the meantime We don't support upgrade path by design.Not sure what you mean here exactly. Upgrade from what to what? Is this documented somewhere? Enforced somehow?
that don't support socket activation to ones that do.
I think that you should simply start with a brand new VM, adding AV repo and installing vdsm. If you use something like this as your new base snapshot everything should work fine for you.Current vdsm versions require libvirt >= 5.6 - versions that have socket activation [1]. There are indeed some leftovers in 'vdsm-tool' that were trying to handle both scenarios, but again - no upgrade paths. 'vdsm-tool' should work for fresh installations without any issues. OK.I was just wondering, see the other thread, "Why is vdsm enabled by default?".I'd clarify my current behavior as a developer. I have a VM I use for hosted-engine testing. I take snapshots of it after installing or upgrading packages, but before '--deploy'. Then I try deploy, play with stuff etc., and eventually revert to the latest snapshot, 'dnf update', and take another snapshot, before trying deploy again.My problem is that on the boot after reversion to a snapshot, vdsm starts and configures stuff, before I try deploy. As you explained, this is currently broken.I now did above again, but reverted to a snapshot from before installing vdsm. Indeed, now I pass the point that failed above.I guess a workaround for my own flow above is to disable vdsmd before taking the snapshot...
Thanks, anyway, and sorry for the noise!
Happy to help! Regards, Marcin
