Convert mainloop to use timeout from default timerlist group (i.e. the current 3 static timers) main-loop.c produces a (possibly spurious) warning about multiple iterations. Adapt the way this works for a signed timeout and make the warning a bit safer. Signed-off-by: NAlex Bligh <alex@alex.org.uk> Signed-off-by: NStefan Hajnoczi <stefanha@redhat.com>

Convert aio_poll to use deadline based on AioContext's timers. aio_poll has been changed to return accurately whether progress has occurred. Prior to this commit, aio_poll always returned true if g_poll was entered, whether or not any progress was made. This required a change to tests/test-aio.c where an assert was backwards.

Split QEMUClock into QEMUClock and QEMUTimerList so that we can have more than one QEMUTimerList associated with the same clock. Introduce a main_loop_timerlist concept and make existing qemu_clock_* calls that actually should operate on a QEMUTimerList call the relevant QEMUTimerList implementations, using the clock's default timerlist. This vastly reduces the invasiveness of this change and means the API stays constant for existing users. Introduce a list of QEMUTimerLists associated with each clock so that reenabling the clock can cause all the notifiers to be called. Note the code to do the notifications is added in a later patch. Switch QEMUClockType to an enum. Remove global variables vm_clock, host_clock and rt_clock and add compatibility defines. Do not fix qemu_next_alarm_deadline as it's going to be deleted. Add qemu_clock_use_for_deadline to indicate whether a particular clock should be used for deadline calculations. When use_icount is true, vm_clock should not be used for deadline calculations as it does not contain a nanosecond count. Instead, icount timeouts come from the execution thread doing aio_notify or qemu_notify as appropriate. This function is used in the next patch.

VMware ESX hosts use a variant of the VMDK3 format, identified by the vmfsSparse create type ad the VMFSSPARSE extent type. It has 16 KB grain tables (L2) and a variable-size grain directory (L1). In addition, the grain size is always 512, but that is not a problem because it is included in the header. The format of the extents is documented in the VMDK spec. The format of the descriptor file is not documented precisely, but it can be found at http://kb.vmware.com/kb/10026353 (Recreating a missing virtual machine disk (VMDK) descriptor file for delta disks). With these patches, vmfsSparse files only work if opened through the descriptor file. Data files without descriptor files, as far as I could understand, are not supported by ESX.

While Asias is debugging an issue creating qcow2 images on top of non-file protocols. It boils down to this example using NBD: $ qemu-io -c 'open -g nbd+unix:///?socket=/tmp/nbd.sock' -c 'read -v 0 512' Notice the open -g option to set bs->growable. This means you can read/write beyond end of file. Reading beyond end of file is supposed to produce zeroes. We rely on this behavior in qcow2_create2() during qcow2 image creation. We create a new file and then write the qcow2 header structure using bdrv_pwrite(). Since QCowHeader is not a multiple of sector size, block.c first uses bdrv_read() on the empty file to fetch the first sector (should be all zeroes). Here is the output from the qemu-io NBD example above: $ qemu-io -c 'open -g nbd+unix:///?socket=/tmp/nbd.sock' -c 'read -v 0 512' 00000000: ab ab ab ab ab ab ab ab ab ab ab ab ab ab ab ab ................ 00000010: ab ab ab ab ab ab ab ab ab ab ab ab ab ab ab ab ................ 00000020: ab ab ab ab ab ab ab ab ab ab ab ab ab ab ab ab ................ ... We are not zeroing the buffer! As a result qcow2 image creation on top of protocols is not guaranteed to work even when file creation is supported by the protocol.

In 4146b46c42e0989cb5842e04d88ab6ccb1713a48 (block: Produce zeros when protocols reading beyond end of file), we break qemu-iotests ./check -qcow2 022. This happens because qcow2 temporarily sets ->growable = 1 for vmstate accesses (which are stored beyond the end of regular image data). We introduce the bs->zero_beyond_eof to allow qcow2_load_vmstate() to disable ->zero_beyond_eof temporarily in addition to enable ->growable. [Since the broken patch "block: Produce zeros when protocols reading beyond end of file" has not been merged yet, I have applied this fix *first* and will then apply the next patch to keep the tree bisectable. -- Stefan] Suggested-by: NStefan Hajnoczi <stefanha@redhat.com> Signed-off-by: NAsias He <asias@redhat.com> Signed-off-by: NStefan Hajnoczi <stefanha@redhat.com>
