2008-10-06Switch the memory savevm handler to be "live"aliguori1-141/+152
This patch replaces the static memory savevm/loadvm handler with a "live" one. This handler is used even if performing a non-live migration. The key difference between this handler and the previous is that each page is prefixed with the address of the page. The QEMUFile rate limiting code, in combination with the live migration dirty tracking bits, is used to determine which pages should be sent and how many should be sent. The live save code "converges" when the number of dirty pages reaches a fixed amount. Currently, this is 10 pages. This is something that should eventually be derived from whatever the bandwidth limitation is.

2008-10-06Introduce v3 of savevm protocolaliguori3-45/+248
The current savevm/loadvm protocol has some draw backs. It does not support the ability to do progressive saving which means it cannot be used for live checkpointing or migration. The sections sizes are 32-bit integers which means that it will not function when using more than 4GB of memory for a guest. It attempts to seek within the output file which means it cannot be streamed. The current protocol also is pretty lax about how it supports forward compatibility. If a saved section version is greater than what the restore code support, the restore code generally treats the saved data as being in whatever version it supports. This means that restoring a saved VM on an older version of QEMU will likely result in silent guest failure. This patch introduces a new version of the savevm protocol. It has the following features: * Support for progressive save of sections (for live checkpoint/migration) * An asynchronous API for doing save * Support for interleaving multiple progressive save sections (for future support of memory hot-add/storage migration) * Fully streaming format * Strong section version checking Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@5434 c046a42c-6fe2-441c-8c8c-71466251a162

This patch adds a dirty tracking bit for live migration. We use 0x08 because kqemu uses 0x04. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@5433 c046a42c-6fe2-441c-8c8c-71466251a162
2008-10-06Add bdrv_flush_all()aliguori2-0/+12
This patch adds a bdrv_flush_all() function. It's necessary to ensure that all IO operations have been flushed to disk before completely a live migration. N.B. we don't actually use this now. We really should flush the block drivers using an live savevm callback to avoid unnecessary guest down time.

2008-10-06Allow the monitor to be suspended during non-blocking opaliguori2-1/+20
Live migration happens in the background, but it is useful to make the monitor command appear as if it's blocking. This allows a management tool to immediately know when the live migration has completed without having to poll the migration status. This patch allows the monitor to be suspended from a monitor callback which will prevent new monitor commands from being executed.

There was a bogus case where two system debug ops get generated. This patch removes the broken system debug op. This was a left over after making some changes to correctly generate debug ops on branch operations inside gen_goto_tb(); The test case against this patch is to turn on single stepping with timers, boot a linux kernel, set a breakpoint a do_fork and in gdb execute "si 3000". Then qemu-system-ppc will fault executing a debug op, which should not have been executed.
