Hi Stefan,
I was part of the report around the series in "[PATCH for-2.10 0/4] block: Fix
non-shared storage migration", but this is happening on rc3 which contains this.
AFAIK Fam's series is:
dd7fdaad iotests: Add non-shared storage migration case 192 (Fam)
5f7772c4 block-backend: Defer shared_perm tightening migration completion (Fam)
3dff24f2 nbd: Fix order of bdrv_set_perm and bdrv_invalidate_cache (Kevin)
80adf54e stubs: Add vm state change handler stubs (Fam)
All these got into v2.10.0-rc3 which these tests are based on already.
IMHO - This is not complete for qemu 2.10 and a regression since 2.9 (well
since 2.8 as I haven't tested 2.9 personally).

--copy-storage-all failing with qemu 2.10
Status in QEMU:
New
Status in libvirt package in Ubuntu:
Confirmed
Status in qemu package in Ubuntu:
Confirmed
Bug description:
We fixed an issue around disk locking already in regard to qemu-nbd
[1], but there still seem to be issues.
$ virsh migrate --live --copy-storage-all kvmguest-artful-normal

Given the timing it seems that the actual copy now works (it is busy ~10
seconds on my environment which would be the copy).
Also we don't see the old errors we saw before, but afterwards on the actual
take-over it fails.
Dmesg has no related denials as often apparmor is in the mix.
Need to check libvirt logs of source [2] and target [3] in Detail.
