I'm apologizing to the Proxmox admins first -- they were very quick to respond to my original post on this topic but I wasn't ready to do the testing they'd asked for. Now that I have the logs they've asked for, I'm hoping I can nudge a response. My forum post is below and I'd appreciate any help you could give. We're due to upgrade all nodes in the cluster this summer to the latest version, but it would be much easier if live migration were working.
