2012-05-14qemu-doc: Use QEMU instead of qemu for product nameStefan Weil
When 'qemu' was used as a product name or as a generic process name, it is now replaced by the official upper case 'QEMU'. v2: Added missing period (hint from Andreas Färber). Reviewed-by: Andreas Färber <afaerber@suse.de> Signed-off-by: Stefan Weil <sw@weilnetz.de>
2012-05-14qemu-doc: Fix executable name in examplesStefan Weil
The executable name qemu was replaced some time ago by qemu-system-i386. Fix all examples accordingly. Some examples will only work with qemu-system-i386 or qemu-system-x86_64 for obvious reasons ("dos.img"). To keep things simple, I did not vary the executable name. Place holders like qemu-system-TARGET were also only used once in the enhanced description for QEMU launches using Wine. Signed-off-by: Stefan Weil <sw@weilnetz.de>

2012-05-13mips_fulong2e: Don't register "cpu" VMState twiceJuan Quintela
We have the following simplified callgraph in mips_fulong2e_init(): cpu_init() => cpu_mips_init() object_new() mips_cpu_initfn() cpu_exec_init() register_savevm(NULL, "cpu", cpu_index, CPU_SAVE_VERSION, cpu_save, cpu_load, env) register_savevm(NULL, "cpu", 0, 3, cpu_save, cpu_load, env) CPU_SAVE_VERSION is defined as 3 in target-mips/cpu.h. fulong2e instantiates one CPU, so its cpu_index is 0. Thus the two are fully identical. Therefore just remove the second call in fulong2e.

2012-05-12target-i386: Defer MCE initAndreas Färber
Commit de024815e3b523addf58f1f79846b7fe74643678 (target-i386: QOM'ify CPU init) moved mce_init() call from helper.c:cpu_x86_init() into X86CPU's cpu.c:x86_cpu_initfn(). mce_init() checks for a family >= 6 though, so we could end up with a sequence such as for -cpu somecpu,family=6: x86_cpu_initfn => X86CPU::family == 5 mce_init => no-op cpu_x86_register => X86CPU::family = 6 => MCE unexpectedly not init'ed or for -cpu someothercpu,family=5: x86_cpu_initfn => X86CPU::family == 6 mce_init => init'ed cpu_x86_register => X86CPU::family = 5 => MCE unexpectedly init'ed Therefore partially revert the above commit. To avoid moving mce_init() back into helper.c, foresightedly move it into a new x86_cpu_realize() function and, in lack of ObjectClass::realize, call it directly from cpu_x86_init(). While at it, move the qemu_init_vcpu() call that used to follow mce_init() in cpu_x86_init() into the new realizefn as well.

2012-05-12vga: disable default VGA if appropriate -device is usedPaolo Bonzini
This is a partial revert of commits a369da5 (vga: improve VGA logic, committed 2012-01-22) and c5bd4f3 (vga: fix -nodefaults -device VGA, 2012-01-24) which broke command-line option parsing in different ways. Since commit a369da5 it has become impossible to specify a VGA device entirely with QemuOpts-enabled options, i.e. without needing an explicit "-vga none". In addition, until commit c5bd4f3 -nodefaults would not disable the device you specified with the legacy "-vga" option, independent of the order. Since commit c5bd4f3 QEMU -nodefaults will override a previous -vga option. I did not reintroduce machine->no_vga. Boards can simply ignore the vga_interface_type variable, and most will indeed do so. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2012-05-10use inet_listen()/inet_connect() to support ipv6 migrationAmos Kong
Use help functions in qemu-socket.c for tcp migration, which already support ipv6 addresses. Currently errp will be set to UNDEFINED_ERROR when migration fails, qemu would output "migration failed: ...", and current user can see a message("An undefined error has occurred") in monitor. This patch changed tcp_start_outgoing_migration()/inet_connect() /inet_connect_opts(), socket error would be passed back, then current user can see a meaningful err message in monitor. Qemu will exit if listening fails, so output socket error to qemu stderr. For IPv6 brackets must be mandatory if you require a port. Referencing to RFC5952, the recommended format is: [2312::8274]:5200 test status: Successed listen side: qemu-kvm .... -incoming tcp:[2312::8274]:5200 client side: qemu-kvm ...

2012-05-10target-arm/cpu.h: Make cpu_init("nonexistent cpu") return NULLPeter Maydell
The macro definition of cpu_init meant that if cpu_arm_init() returned NULL this wouldn't result in cpu_init() itself returning NULL.

2012-05-10stream: do not copy unallocated sectors from the basePaolo Bonzini
Unallocated sectors should really never be accessed by the guest, so there's no need to copy them during the streaming process. If they are read by the guest during streaming, guest-initiated copy-on-read will copy them (we're in the base == NULL case, which enables copy on read). If they are read after we disconnect the image from the base, they will read as zeroes anyway. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2012-05-10stream: fix ratelimiting corner casePaolo Bonzini
This fixes inability to make progress in streaming if the quota is set to less than the amount of data that an I/O operation has to write. In this case, limit->dispatched + n will always be above the quota and, due to the "goto retry" to recheck cancellation and allocation, streaming will livelock. This can be reproduced with "block_job_set_speed ide0-hd0 1b". Of course, with this patch the requested limit will not be obeyed. That could be done with another patch that caps is_allocated's n argument by the slice quota. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

We cannot fully protect against this in case the filename does not have a path component (e.g. if the current directory is /dev/disk/by-path), but in the common case there will be a slash before and path_has_protocol can easily detect that and return false.
