Known issues

Please list all patch series or bugs which need to be fixed for the release here. That way I can be sure I don't miss any when I'm rolling release candidates.

Not yet fixed in any rc

• virtio-balloon/migration compatibility: There's a migration break between 3.1<->4.x; reported by Wolfgang Bumiller; fixed by stefan's virtio-balloon: fix QEMU 4.0 config size migration incompatibility 2019-07-10 - fixed by 2bbadb08ce272d65e1f78621002008b07d1e0f03
• migration: migratie/migrate_cancel/migrate: Ivan Ren's post from 14th July - 'migration: always initial RAMBlock.bmap to 1 for new migration' - fixed by 40c4d4a835453452a262f32450a0449886aa19ce
• The virtio-pmem device is "at-risk" as it uses a kernel ABI that has not yet been accepted into mainline; this will be reverted if the kernel changes don't get accepted before rc3.
• x86 --without-default-devices is broken due to CONFIG_VMMOUSE being "select"ed.
