Subject: qemu assert in staging during HVM live migration
Date: Thu, 22 Nov 2018 11:03:45 +0100	[thread overview]
Message-ID: <20181122100344.GA13748@aepfle.de> (raw)


[-- Attachment #1.1.1: Type: text/plain, Size: 629 bytes --]

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'.
