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 rc1

QEMU aborts with: aarch64-softmmu/qemu-system-aarch64 -M virt -device ramfb

Fixed in rc2

QEMU crashes with: qemu-system-aarch64 -M n800 (without any additional parameters) - this used to work better with v3.0
We are missing the -3.1 versioned machine types for the PC machines. Patch on the list: https://lists.nongnu.org/archive/html/qemu-devel/2018-11/msg03904.html

Fixed in rc3

QEMU currently can't be compiled with "--disable-replication"
QEMU crashes at startup on older AMD systems with: error: failed to set MSR 0x10a to 0x0
Source QEMU crashes during migration when format and protocol block nodes were created separately (typical -blockdev setup). Fix is on the list: https://lists.gnu.org/archive/html/qemu-block/2018-11/msg00759.html
QEMU crashes with virtio-scsi on IO error (lp 1804323)

Not yet fixed in any rc

Various thread titles that have raised the question of whether they are appropriate for 3.1, in no particular order. Several of them state they do not warrant -rc4 on their own, but may be worth including if another major change forces -rc4. CVEs may force -rc4, but other threads may still be moved to Won't fix.

usb-mtp: two bugfixes (one security fix) (CVE-2018-16867)
net: Fix possible OOB during queuing packets (CVE-2018-17963)
NBD dirty bitmap cleanups
pc:piix4: Update smbus I/O space after a migration
mirror dead-lock
egl-headless: add egl-create-context
hostmem: Validate host-nodes before setting bitmap

Will not be fixed in this release

QEMU may not work on the OSX "Mojave" release if the GUI is being used (it's not clear what the circumstances where it fails are)
SMMUv3 ACPI integration ([PATCH for-3.1] hw/arm/virt-acpi-build: Fix SMMUv3 ACPI integration)
Disassembly of nanomips code may give incorrect immediate values on big-endian host systems
9p: remove support for the "handle" backend
i2c: Move typedef of bitbang_i2c_interface to i2c.h (fixes compilation failure with clang 3.4) -- can be worked around with configure --disable-werror, which is the default for a release
fix some segmentation faults and migration issues -- issues are minor and not regressions
glib-compat: work around g_test_message bug with subprocess tests (our current set of tests don't hit this bug)
qemu-iotests: Don't run the test when user is root (not a regression, none of our tests should be run as root)
