[libvirt-users] Attempt to migrate guest to the same host localhost.localdomain

[llilulu]

Hi
My libvirt version is 3.4.0, I migrate guest between two host, The two host have same hostname( hostname cmd output same), I try find solution on Internet, I find someone say host uuid same, But virsh sysinfo output uuid is different, when I change one host's hostname, migrate success. I wish know why, and Can I solution this problem not change hostname.
My program use api virDomainMigrateToURI2, flag arg is VIR_MIGRATE_LIVE | VIR_MIGRATE_PEER2PEER . I use virsh migrate --live --p2p.
Thanks

Libvirt on the source host will query libvirt on the target host to
discover its hostname, which is then used as the target for the migration
in QEMU, so you really need a proper hostname configured.
