2009-05-22kvm: Add missing bits to support live migrationJan Kiszka
This patch adds the missing hooks to allow live migration in KVM mode. It adds proper synchronization before/after saving/restoring the VCPU states (note: PPC is untested), hooks into cpu_physical_memory_set_dirty_tracking() to enable dirty memory logging at KVM level, and synchronizes that drity log into QEMU's view before running ram_live_save().

2009-05-22kvm: Rework dirty bitmap synchronizationJan Kiszka
Extend kvm_physical_sync_dirty_bitmap() so that is can sync across multiple slots. Useful for updating the whole dirty log during migration. Moreover, properly pass down errors the whole call chain.

2009-05-22kvm: Fix dirty log temporary buffer sizeJan Kiszka
The buffer passed to KVM_GET_DIRTY_LOG requires one bit per page. Fix the size calculation in kvm_physical_sync_dirty_bitmap accordingly, avoiding allocation of extremly oversized buffers. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-05-22kvm: Introduce kvm_set_migration_logJan Kiszka
Introduce a global dirty logging flag that enforces logging for all slots. This can be used by the live migration code to enable/disable global logging withouth destroying the per-slot setting. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-05-22kvm: Conditionally apply workaround for KVM slot handling bugJan Kiszka
Only apply the workaround for broken slot joining in KVM when the capability was not found that signals the corresponding fix existence. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-05-22qcow2: Allow different cluster sizesKevin Wolf
Add an option to specify the cluster size of a newly created qcow2 image. Default is 4k which is the same value that was hard-coded before. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-05-22Convert qemu-img convert to new bdrv_createKevin Wolf
This is part two of the qemu-img conversion. This really works the same as the previous conversion of qemu-img create: It introduces a new -o option for the generic approach and adds the old-style options to this option set. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-05-22Convert qemu-img create to new bdrv_createKevin Wolf
This patch changes qemu-img to actually use the new bdrv_create interface. It translates the old-style qemu-img options which have been bdrv_create2 parameters or flags so far to option structures. As the generic approach, it introduces an -o option which accepts any parameter the driver knows. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-05-22Convert all block drivers to new bdrv_createKevin Wolf
Now we can make use of the newly introduced option structures. Instead of having bdrv_create carry more and more parameters (which are format specific in most cases), just pass a option structure as defined by the driver itself. bdrv_create2() contains an emulation of the old interface to simplify the transition. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-05-22Create qemu-option.hKevin Wolf
This patch creates a new header file and the corresponding implementation file for parsing of parameter strings for options (like used in -drive). Part of this is code moved from vl.c (so qemu-img can use it later). The idea is to have a data structure describing all accepted parameters. When parsing a parameter string, the structure is copied and filled with the parameter values. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-05-22allow changing the speed of a running migrationGlauber Costa
This patch allow us to call migrate_set_speed on running migrations. This should allow mgmt tools to increase the allocated bandwidth of a running migration if there is no progress, and they really want the migration to succeed.

2009-05-22augment info migrate with page statusGlauber Costa
This patch augments info migrate output with status about: * ram bytes remaining * ram bytes transferred * ram bytes total This should be enough for management tools to realize whether or not there is progress in migration. We can add more information later on, if the need arrives [v2: fixes bytes_transferred type] Signed-off-by: Glauber Costa <glommer@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

From Paul Brook: "the fdc is tied to the ISA DMA engine. We don't currently have a target independent method of handling inter-device data transfer." Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-05-22Revert "Fix arm-softmmu breakage"Anthony Liguori
This reverts commit ec6bd8dea77478f32981a5df49f66ca2430ad19d. This broke any target that uses virtio. Virtio devices live in libhw and without whole-archive, the constructors will never be called for virtio. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-05-21Introduce is_default field for QEMUMachineAnthony Liguori
f80f9ec changed the order that machines are registered which had the effect of changing the default machine. This changeset introduces a new is_default field so that machine types can declare that they are the default for an architecture. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-05-21Refactor how display drivers are selectedAnthony Liguori
My previous commit, f92f8afebe, broke -vnc (spotted by Glauber Costa). This is because it's necessary to tell when the no special display parameters have been passed and default to SDL or VNC appropriately. This refactors the display selection logic to be less complicated which has the effect of fixing the regression mentioned above. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2009-05-21Eliminate --disable-gfx-check and make VNC default when SDL not availableAnthony Liguori
--disable-gfx-check predates VNC server support. It made sense back then because the only thing you could do without SDL was use -nographic mode or similar tricks. Since this is a very advanced mode of operation, gfx-check provided a good safety net for casual users. A casual user is very likely to use VNC to interact with a guest. In fact, it's often frustrating to install QEMU on a server and have to specify disable-gfx-check when you only want to use VNC. This patch eliminates disable-gfx-check and makes SDL behave like every other optional dependency. If SDL is not available, instead of failing ungracefully if no special options are specified, we default to -vnc localhost:0,to=99. When we do default to VNC, we also print a message to tell the user that we've done this include which port we're currently listening on. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

This text is no longer accurate. After the patch is applied, the generated version at http://www.nongnu.org/qemu/qemu-doc.html should be regenerated. This patch is also a candidate for the stable branch. (The URL above is probably generated from the stable branch anyways, so maybe it goes without saying.)

The only target dependency for most hardware is sizeof(target_phys_addr_t). Build these files into a convenience library, and use that instead of building for every target.
