* libxl: Change claim_mode from bool to int.Konrad Rzeszutek Wilk2013-05-141-3/+3
| | | | | | | | | | | | | | | | | During the review it was noticed that it would be better if internally the claim_mode was held as an 'int' instead of a 'bool'. The reason is that during the startup of xl, one has call the libxl_defbool_setdefault. otherwise any usage of claim_mode would result in assert break. The assert is due to the fact that using defbool without any set values (either true of false) will cause it hit an assertion. If we use an 'int' we don't have to worry about it and by default the value of zero will suffice for checks whether the claim is enabled or disabled.

* xl: Implement XENMEM_claim_pages support via 'claim_mode' global configKonrad Rzeszutek Wilk2013-04-161-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The XENMEM_claim_pages hypercall operates per domain and it should be used system wide. As such this patch introduces a global configuration option 'claim_mode' that by default is disabled. If this option is enabled then when a guest is created there will be an guarantee that there is memory available for the guest. This is an particularly acute problem on hosts with memory over-provisioned guests that use tmem and have self-balloon enabled (which is the default option for them). The self-balloon mechanism can deflate/inflate the balloon quickly and the amount of free memory (which 'xl info' can show) is stale the moment it is printed. When claim is enabled a reservation for the amount of memory ('memory' in guest config) is set, which is then reduced as the domain's memory is populated and eventually reaches zero. If the reservation cannot be meet the guest creation fails immediately instead of taking seconds/minutes (depending on the size of the guest) while the guest is populated. Note that to enable tmem type guests, one needs to provide 'tmem' on the Xen hypervisor argument and as well on the Linux kernel command line. There are two boolean options: (0) No claim is made. Memory population during guest creation will be attempted as normal and may fail due to memory exhaustion. (1) Normal memory and freeable pool of ephemeral pages (tmem) is used when calculating whether there is enough memory free to launch a guest. This guarantees immediate feedback whether the guest can be launched due to memory exhaustion (which can take a long time to find out if launching massively huge guests) and in parallel. [v1: Removed own claim_mode type, using just bool, improved docs, all per Ian's suggestion] [v2: Updated the comments] [v3: Rebase on top 733b9c524dbc2bec318bfc3588ed1652455d30ec (xl: add vif.default.script)] [v4: Fixed up comments] [v5: s/global_claim_mode/claim_mode/] [v6: Ian Jackson's feedback: use libxl_defbool, better comments, etc] Signed-off-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com> Acked-by: Ian Jackson <ian.jackson@eu.citrix.com>
* xl: default autoballoon option to "auto"David Vrabel2013-04-081-2/+4

| | | | | | | | | | | | | | | | | | autoballoon=1 is not recommened if dom0_mem was used to reduce the amount of dom0 memory. Instead of requiring users to change xl.conf if they do this, extend the autoballoon option with a new choice: "auto". With autoballoon="auto", autoballooning will be disabled if dom0_mem was used on the Xen command line. For consistency, accept "on" and "off" as valid autoballoon options (1 and 0 are still accepted). The default remains "on" for now.

* xl: track child processes for the benefit of libxlIan Jackson2012-05-291-13/+73
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Each time xl forks, it needs to record the pid, so that its exit status can be preserved if it happens that libxl's event loop reaped it. Consequently we also have a new wrapper for waitpid, which in that case returns the previously-reaped status. When we get a console ready callback from libxl, check to see if we have spawned but not reaped a previous console client, and if so reap it now. (This is necessary to prevent improper use of the xlchild struct, but has the happy consequence of checking the exit status of the first console client in the pygrub case.) Refactor the two calls to libxl_ctx_alloc into a new function xl_ctx_alloc which also sets the child reaped handler callback. All of this has the effect of suppressing a message unknown child [nnnn] unexpected exited status zero which would sometimes (depending on a race) appear with `xl create -c' and pygrub.

Its functionality is now moved elsewhere, as follows: * The "logging version of fork", which is what it was billed as, is now xl_fork, which also dies on failure. * Closing the xenstore handle in the child is now done in libxl__ev_child_fork, which is the only remaining place where fork is called in libxl. * We provide a new function libxl__ev_child_xenstore_reopen for in-libxl children to make the ctx useable for xenstore again. * Consequently libxl__spawn_record_pid now no longer needs to mess about with its own xenstore handle. As a bonus it can now just use libxl__xs_write. Also, since we have now converted all the forkers in libxl, we can always honour the fork_replacement childproc hook - so do so.

* libxl: Protect fds with CLOEXEC even with forking threadsIan Jackson2012-04-111-0/+3
| | | | | | | | | | | | | | | | | | | We introduce a new "carefd" concept, which relates to fds that we care about not being inherited by long-lived children. As yet we do not use this anywhere in libxl. Until all locations in libxl which make such fds are converted, libxl__postfork may not work entirely properly. If these locations do not use O_CLOEXEC (or use calls for which there is no O_CLOEXEC) then multithreaded programs may not work properly. This introduces a new API call libxl_postfork_child_noexec which must be called by applications which make long-running non-execing children. Add the appropriate call to xl's postfork function.

| | | | | | | | | | | | | | | | | | | | | Move the sxp producing code off into a separate file. It is supported for legacy reasons and needn't be updated other than the improve compatibility with xm. libxl_domain_config is not currently generated by the IDL (adding the necessary support for Array types is on my to do list) so hand code the json generation function for now. Since this rather directly exposes a libxl data structure it's not clear what sort of forward compatibility guarantees we can make.

* xl: treat sub-command main function like a regular C main() functionIan Campbell2010-08-241-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | Currently xl passes the entire argc+argv to each subcommand and relies on the preservation of the global optind variable to ensure that the subcommand correctly handles argument parsing (e.g. accounting for "xl [command]" vs "xl -v [command]"). This requirement for individual sub-commands to parse arguments relative to optind is subtle and prone to being forgotten (or simply not expected). Several sub-commands have recently been broken in this way (now fixed). Therefore arrange that the argv+argc passed to the sub-commands looks like you would expect for a regular C main function and includes argv[0] equal to the command name with command specific arguments in argv[1] onwards. Since all sub-commands (currently) correctly obey the optind it is sufficient to reset it to 1 (as described in getopt(3)) in order to not break the sub-commands' own argument parsing.
