...ersion 3.4 and 4.1) re-creates the domain information located in XenStore below /vm/$UUID. (According to the xen-3.2-commit hg265950e3df69 to fix a problem when locally migrating a domain to the host itself.) When doing so a version number is added to the UUID separated by one dash, which confuses xenStoreDomainIntroduced(): It iterates over all domains and tries to lookup all inactive domains using xenStoreDomainGetUUID(), which fails if the running domain is renamed: virUUIDParse() fails to parse the versioned UUID and the domain is flagged as missing. When this happens the function delays .2s and re-tries 20 time...
