System emulation

Device emulation

Device assignment

USB

ARM

MIPS

PowerPC

  • Pseries: NVRAM support for improved guest installation experience
  • e500: Linux guests don't use use SWTLB anymore, freeing memory for real applications
  • e500: MSI support
  • e500: Allow for up to 31 PCI devices with -M ppce500
  • e500: Support idle hcall when running KVM on e500mc or above
  • e500: Emulate the EPR facility (e500mc and above)

S390

x86

  • testdev?

KVM

Xen

  • persistent grants support implemented in xen_disk (up to 450% speed in improvement with 15 guests!!);
  • safer and correcter flush operation (BLKIF_OP_FLUSH_DISKCACHE) introduced in xen_disk;
  • multiple secondary PV consoles support in xen_console;
  • many bug fixes.

QMP

Network devices

SLIRP

Block devices

Live Migration

Move migration from a timer to a thread. Migration was blocking the iothread for too long. Latency of the other threads have improved, and measurements/throughput/latency of migration has also improved.

User-mode emulation

  • Fix ppc guest signal handling
  • Fix MIPS target

Guest agent

Host support
