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

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

Fixed in rc4

  • M-profile CPUs with FPU but without Security Extensions do bogus NSACR checks (LP:1838475)
  • We forgot to update the slirp submodule
  • The backup job’s use of copy offloading is broken
  • A mirror job with copy-mode=write-blocking may fail to copy some data from the source
  • Performing an incremental backup with a bitmap that had been added to a block node before it was grown with block_resize will ignore all dirty areas past the node’s original size
  • Compat handling turns off 'edid' only for virtio-gpu-pci, but not for virtio-gpu-ccw

Fixed in rc5

  • PPC bugs with the XIVE interrupt controller for spapr
  • Makefile issue if you're building the risc-v bios blobs from source
  • Security bug with bochs-display device

Not yet fixed in any rc

Issues that will not be fixed

  • s390x TCG: The VERIM instruction can make QEMU crash

Targeted Features
