* libxl,xl: add max_event_channels option to xl configuration fileDavid Vrabel2013-10-145-0/+19
| | | | | | | | | | | | | | | | | | | Add the 'max_event_channels' option to the xl configuration file to limit the number of event channels that domain may use. Plumb this option through to libxl via a new libxl_build_info field and call xc_domain_set_max_evtchn() in the post build stage of domain creation. A new LIBXL_HAVE_BUILDINFO_EVENT_CHANNELS #define indicates that this new field is available. The default value of 1023 limits the domain to using the minimum amount of global mapping pages and at most 5 xenheap pages.

* Add DOMCTL to limit the number of event channels a domain may useDavid Vrabel2013-10-142-2/+2
| | | | | | | | | | | | | | | Add XEN_DOMCTL_set_max_evtchn which may be used during domain creation to set the maximum event channel port a domain may use. This may be used to limit the amount of Xen resources (global mapping space and xenheap) that a domain may use for event channels. A domain that does not have a limit set may use all the event channels supported by the event channel ABI in use.

* tools/migrate: Fix regression when migrating from older version of XenAndrew Cooper2013-10-1012-16/+67
| | | | | | | | | | | | | | | | | | | | | | | | | Commit 00a4b65f8534c9e6521eab2e6ce796ae36037774 Sep 7 2010 "libxc: provide notification of final checkpoint to restore end" broke migration from any version of Xen using tools from prior to that commit Older tools have no idea about an XC_SAVE_ID_LAST_CHECKPOINT, causing newer tools xc_domain_restore() to start reading the qemu save record, as ctx->last_checkpoint is 0. The failure looks like: xc: error: Max batch size exceeded (1970103633). Giving up. where 1970103633 = 0x756d6551 = *(uint32_t*)"Qemu" With this fix in place, the behaviour for normal migrations is reverted to how it was before the regression; the migration is considered non-checkpointed right from the start. A XC_SAVE_ID_LAST_CHECKPOINT chunk seen in the migration stream is a nop. For checkpointed migrations the behaviour is unchanged.

| | | | | | | | | | | | | | | Coverity complains about the use of strncpy() to completely fill the anchor strings, resulting in an unterminated string.
