The goal of this patch is to have a stable core-id which does not depend on any DT related semantics, which involve non-obvious computations on modern PowerPC server cpus. With this patch, the DT core id is computed on-demand as: (core-id / smp_threads) * smt where smt is the number of threads per core in the host. This formula should be consolidated in a helper since it is needed in several places. Other uses for core-id includes: compute a stable cpu_index (which allows random order hotplug/unplug without breaking migration) and NUMA.

When spapr-nvram is backed by a file using pflash interface, migration fails on the destination guest with assert: bdrv_co_pwritev: Assertion `!(bs->open_flags & 0x0800)' failed. This avoids the problem by delaying the pflash update until after the device loads complete. This fix is similar to the one for the pflash_cfi01 migration: 90c647db Fix pflash migration Signed-off-by: NLaurent Vivier <lvivier@redhat.com> Reviewed-by: NPaolo Bonzini <pbonzini@redhat.com> Signed-off-by: NDavid Gibson <david@gibson.dropbear.id.au>

When canceling a migration process, we currently do not close the HTAB migration file descriptor since htab_save_complete() is never called in that case. So we leave the migration process with a dangling htab_fd value around, and this causes any further migration attempts to fail. To fix this issue, simply make sure that the htab_fd is closed during the migration cleanup stage. And since the cleanup() function is also called when migration succeeds, we can also remove the call to close_htab_fd() from the htab_save_complete() function.

After already fixing two issues with the huge page detection mechanism (see commit 159d2e39 and 86b50f2e), Greg Kurz noticed another case that caused the guest to crash where QEMU announces huge pages though they should not be available for the guest: qemu-system-ppc64 -enable-kvm ... -mem-path /dev/hugepages \ -m 1G,slots=4,maxmem=32G -object memory-backend-ram,policy=default,size=1G,id=mem-mem1 \ -device pc-dimm,id=dimm-mem1,memdev=mem-mem1 -smp 2 \ -numa node,nodeid=0 -numa node,nodeid=1 That means if there is a global mem-path option, we still have to look at the memory-backend objects that have been specified additionally and return their minimum page size if that value is smaller than the page size of the main memory.

This introduces a moderately general purpose framework for testing performance of migration. The initial guest workload is provided by the included 'stress' program, which is configured to spawn one thread per guest CPU and run a maximally memory intensive workload. It will loop over GB of memory, xor'ing each byte with data from a 4k array of random bytes. This ensures heavy read and write load across all of guest memory to stress the migration performance. While running the 'stress' program will record how long it takes to xor each GB of memory and print this data for later reporting. The test engine will spawn a pair of QEMU processes, either on the same host, or with the target on a remote host via ssh, using the host kernel and a custom initrd built with 'stress' as the /init binary. Kernel command line args are set to ensure a fast kernel boot time (< 1 second) between launching QEMU and the stress program starting execution. None the less, the test engine will initially wait N seconds for the guest workload to stablize, before starting the migration operation. When migration is running, the engine will use pause, post-copy, autoconverge, xbzrle compression and multithread compression features, as well as downtime & bandwidth tuning to encourage completion. If migration completes, the test engine will wait N seconds again for the guest workooad to stablize on the target host. If migration does not complete after a preset number of iterations, it will be aborted. While the QEMU process is running on the source host, the test engine will sample the host CPU usage of QEMU as a whole, and each vCPU thread. While migration is running, it will record all the stats reported by 'query-migration'. Finally, it will capture the output of the stress program running in the guest. All the data produced from a single test execution is recorded in a structured JSON file. A separate program is then able to create interactive charts using the "plotly" python + javascript libraries, showing the characteristics of the migration. The data output provides visualization of the effect on guest vCPU workloads from the migration process, the corresponding vCPU utilization on the host, and the overall CPU hit from QEMU on the host. This is correlated from statistics from the migration process, such as downtime, vCPU throttling and iteration number. While the tests can be run individually with arbitrary parameters, there is also a facility for producing batch reports for a number of pre-defined scenarios / comparisons, in order to be able to get standardized results across different hardware configurations (eg TCP vs RDMA, or comparing different VCPU counts / memory sizes, etc). To use this, first you must build the initrd image $ make tests/migration/initrd-stress.img To run a a one-shot test with all default parameters $ ./tests/migration/guestperf.py > result.json This has many command line args for varying its behaviour. For example, to increase the RAM size and CPU count and bind it to specific host NUMA nodes $ ./tests/migration/guestperf.py \ --mem 4 --cpus 2 \ --src-mem-bind 0 --src-cpu-bind 0,1 \ --dst-mem-bind 1 --dst-cpu-bind 2,3 \ > result.json Using mem + cpu binding is strongly recommended on NUMA machines, otherwise the guest performance results will vary wildly between runs of the test due to lucky/unlucky NUMA placement, making sensible data analysis impossible. To make it run across separate hosts: $ ./tests/migration/guestperf.py \ --dst-host somehostname > result.json To request that post-copy is enabled, with switchover after 5 iterations $ ./tests/migration/guestperf.py \ --post-copy --post-copy-iters 5 > result.json Once a result.json file is created, a graph of the data can be generated, showing guest workload performance per thread and the migration iteration points: $ ./tests/migration/guestperf-plot.py --output result.html \ --migration-iters --split-guest-cpu result.json To further include host vCPU utilization and overall QEMU utilization $ ./tests/migration/guestperf-plot.py --output result.html \ --migration-iters --split-guest-cpu \ --qemu-cpu --vcpu-cpu result.json NB, the 'guestperf-plot.py' command requires that you have the plotly python library installed. eg you must do $ pip install --user plotly Viewing the result.html file requires that you have the plotly.min.js file in the same directory as the HTML output. This js file is installed as part of the plotly python library, so can be found in $HOME/.local/lib/python2.7/site-packages/plotly/offline/plotly.min.js The guestperf-plot.py program can accept multiple json files to plot, enabling results from different configurations to be compared. Finally, to run the entire standardized set of comparisons $ ./tests/migration/guestperf-batch.py \ --dst-host somehost \ --mem 4 --cpus 2 \ --src-mem-bind 0 --src-cpu-bind 0,1 \ --dst-mem-bind 1 --dst-cpu-bind 2,3 --output tcp-somehost-4gb-2cpu will store JSON files from all scenarios in the directory named tcp-somehost-4gb-2cpu Signed-off-by: NDaniel P.

If a migration fails/is cancelled during the postcopy stage we currently end up with the runstate as finish-migrate, where it should be post-migrate. There's a small window in precopy where I think the same thing can happen, but I've never seen it. It rarely matters; the only postcopy case is if you restart a migration, which again is a case that rarely matters in postcopy because it's only safe to restart the migration if you know the destination hasn't been running (which you might if you started the destination with -S and hadn't got around to 'c' ing it before the postcopy failed). Even then it's a small window but potentially you could hit if there's a problem loading the devices on the destination.
