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.
Fixed in rc0
Fixed in rc1
- 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
Fixed in rc2
- x86 --without-default-devices is broken due to CONFIG_VMMOUSE being "select"ed.
- The virtio-pmem device is no longer "at-risk" -- the kernel header changes got taken into mainline without changes that require us to resync or to revert the QEMU side changes
Will be fixed in rc3
- snowridge cpu name/features
- coverity issue in block/nvme
- virtio devices seem to have lost PCIe capability and PCIe powermanagement capabilities (David Gilbert posted revert's for 'report invalid disable-legacy|modern usage for virtio-1-only devs')
- copy-on-read migration permissions issue
- inserting read-only image to initially empty scsi-cd is incorrectly rejected
- inserting read-only image to initially empty floppy drive is incorrectly rejected
- arm emulated BKPT/BRK insn at EL2 can be taken to EL1
- unwanted ACS capability on PCI bridges on old machine types
Not yet fixed in any rc
- The backup job’s use of copy offloading is broken
- M-profile CPUs with FPU but without Security Extensions do bogus NSACR checks (LP:1838475)
- We forgot to update the slirp submodule
