ChangeLog/1.1
System emulation
All targets
- qdev properties of type hex8 and hex32 used to accept hexadecimal values not prefixed with "0x"; the prefix is mandatory starting with this version. These properties are: iobase, membase, io_base for all devices that support the properties; vram_size for sysbus-g364 and SUNW,tcx; version for sb16 and iommu; ctl_iobase and data_iobase for fw_cfg; readback for debugcon; elcr_addr and elcr_mask for i8259.
PCI addresses can still be addressed with a pair of hexadecimal device and function without a "0x" prefix. - -kernel, -initrd and -append are now aliases for suboptions of -machine (for example -machine kernel=foo), and as such they are also available with -readconfig.
ARM
- The syborg machine type has been removed since the Symbian Virtual Platform is no longer relevant with the disbanding of Symbian.
- [new machine types]
PowerPC
- Bamboo now works with TCG
- Pseries handles PCI
- Pseries works with PR KVM
S/390
- -kernel now also supports ELF binaries
- -kernel can boot new guest kernels
- Devices can now be hotplug add'ed (remove is not there yet)
x86
- The -rtc-td-hack option is now available as a qdev property (-global mc146818rtc.lost_tick_policy=slew) and as such can be specified in a -readconfig configuration file.
- [S3 support]
- KVM can optionally use kernel-based emulation of the local APIC, IOAPIC and i8259 PIC. This is supported with the -machine ...,kernel_irqchip=on command-line option. MSI is not supported yet when using the kernel_irqchip option.
- [pflash stuff]?
Device emulation
- The virtio-scsi device is now supported by QEMU. The guest driver will be supported in Linux starting at version 3.4.
- QEMU now includes experimental support for USB 3.0 (xHCI).
Block devices
- QEMU's NBD client implementation and the qemu-nbd server both fully support asynchronous I/O.
- [streaming]
Live Migration, Save/Restore
- Live migration (or save/restore) from QEMU releases prior to 0.13 to QEMU 1.1 is not supported
Guest agent
- qemu-ga has been ported to Windows.
Host support
- System emulation on ARM hosts was broken in 1.0 and works again
User-mode emulation
- User-mode emulation can provide some information from the /proc filesystem.
