[Xen-devel] qemu assert in staging during HVM live migration

[Olaf Hering <olaf@xxxxxxxxx>]

While debugging something else, it turned out that staging and/or qemu
can not migrate HVM domUs. qemu runs into an assert when the domU is
about to be migrated with 'xl migrate domU dom0':

qemu-system-i386: block/block-backend.c:903: blk_get_attached_dev_id: Assertion 
`!blk->legacy_dev' failed.

Using /usr/bin/qemu-system-i386 from qemu-3.1 failed as well.
The workaround was to enforce my own qemu-2.12.

Since I have very very little runtime available on that system, thats
all the info I could collect.
Any idea what might be wrong? That 'legacy' code is in qemu since a few
years already, according to 'git blame'.
