Title:
  unable to migrate non shared storage when TLS is used

Status in QEMU:
  New

Bug description:
  Operating system: Gentoo
  Architecture: x86_64
  kernel version: 5.4.72, 5.10.11
  libvirt version: at least 6.9.0, 6.10.0, 7.0.0
  Hypervisor and version: qemu 5.1.0, 5.2.0

  With software versions described above and following configurations:
  libvirt:
  key_file = "/etc/ssl/libvirt/server.lan.key"
  cert_file = "/etc/ssl/libvirt/server.lan.crt"
  ca_file = "/etc/ssl/libvirt/ca.crt"
  log_filters="3:remote 4:event 3:util.json 3:rpc 1:*"
  log_outputs="1:file:/var/log/libvirt/libvirtd.log"
  qemu:
  default_tls_x509_cert_dir = "/etc/ssl/qemu"
  default_tls_x509_verify = 1
  migration with tls:
  virsh # migrate vm1 qemu+tls://server2.lan/system --persistent 
--undefinesource --copy-storage-all --verbose --tls
  never succeeds. Progress stops typically at high progress amounts (95%-98%), 
and network traffic drastically drops as well (from 1 gbps+ to nothing). 
domjobinfo progress also stops. Without --tls migrations succeed without issues 
without any other changes to hosts or configurations.
