* libxl,xl: add max_event_channels option to xl configuration fileDavid Vrabel2013-10-141-0/+11
| | | | | | | | | | | | | | | | | | | 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.

* xl: update the manpage about "cpus=" and NUMA node-affinityDario Faggioli2013-10-101-7/+15
| | | | | | | | | | | | | | | Since d06b1bf169a01a9c7b0947d7825e58cb455a0ba5 ('libxl: automatic placement deals with node-affinity') it is no longer true that, if no "cpus=" option is specified, xl picks up some pCPUs by default and pin the domain there. In fact, it is the NUMA node-affinity that is affected by automatic placement, not vCPU to pCPU pinning. Update the xl config file documenation accordingly, as it seems to have been forgotten at that time.

* libxl: Remove qxl support for the 4.3 releaseGeorge Dunlap2013-05-301-9/+1
| | | | | | | | | | | | | | | | | | | | | | | | | The qxl drivers for Windows and Linux end up calling instructions that cannot be used for MMIO at the moment. Just for the 4.3 release, remove qxl support. This patch should be reverted as soon as the 4.4 development window opens. The issue in question: (XEN) emulate.c:88:d18 bad mmio size 16 (XEN) io.c:201:d18 MMIO emulation failed @ 0033:7fd2de390430: f3 0f 6f 19 41 83 e8 403 The instruction in question is "movdqu (%rcx),%xmm3". Xen knows how to emulate it, but unfortunately %xmm3 is 16 bytes long, and the interface between Xen and qemu at the moment would appear to only allow MMIO accesses of 8 bytes. It's too late in the release cycle to find a fix or a workaround.

* xl: Fix 'free_memory' to include outstanding_claims value.Konrad Rzeszutek Wilk2013-04-162-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Updating to make it clear that free_memory reported by 'xl info' is influenced by the outstanding claim value. That is the free memory that will be available to the host once all outstanding claims have been completed. This modifies the behavior that the patch titled "xl: 'xl info' print outstanding claims if enabled (claim_mode=1 in xl.conf)" had - which reported the outstanding claims and nothing else. The free_pages as reported by the hypervisor is the currently available count of pages on the heap. The outstanding pages is the total amount of pages reserved for guests (so not taken from the heap yet). As guests are being populated the memory from the heap shrinks and the outstanding count of pages decreases. The total memory used for guests increases. As the available count of pages on the heap and outstanding claims are intertwined, report the amount of free memory available to be a combination of that. That is free heap memory minus the outstanding pages. We also make some odd choices in reporting. By default we will only display 'outstanding_claims' if the claim_mode is enabled in the global configuration file. However, if there are outstanding claims, we will ignore the claim_mode and report these values.

* xl: 'xl claims' print outstanding per domain claimsKonrad Rzeszutek Wilk2013-04-161-0/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is similar to "xl: 'xl info' print outstanding claims if enabled (claim_mode=1 in xl.conf)" which exposes the global claim value. This patch provides the value of the currently outstanding pages claimed for each domains. This is per domain value which is added to the global claim value which influences the hypervisors' MM system. When a claim call is done, a reservation for a specific amount of pages is set (and this patch lists said number) and also a global value is incremented. This global value is then reduced as the domain's memory is populated and eventually reaches zero. The toolstack (libxc) also sets the domain's claim to zero when the population of memory has completed as an extra step. Any call to destroy the domain will also set the domain's claim to zero. If the reservation cannot be meet the guest creation fails immediately instead of taking seconds or minutes (depending on the size of the guest) while the toolstack populates memory. See patch: "xl: Implement XENMEM_claim_pages support via 'claim_mode' global config" for details on how it is implemented. The value fluctuates quite often so the value is stale once it is provided to the user-space. However it is useful for diagnostic purposes. It is printed irregardless of global "claim_mode" option in xl.conf(5). That is b/c the user might have enabled, launched a guest, and then disabled the option - and we should still report the correct outstanding claim value. The 'man xl' shows the details of this argument. The output is close to what 'xl list' looks like: Name ID Mem VCPUs State Time(s) Claimed Domain-0 0 2047 4 r----- 19.7 0 OL5 2 2048 1 --p--- 0.0 847 OL6 3 1024 4 r----- 5.9 0 Windows_XP 4 2047 1 --p--- 0.0 1989 [In which it can be seen that the OL5 guest still has 847MB of claimed memory (out of the total 2048MB where 1191MB has been allocated to the guest).] Please note that the 'Mem' column has the cumulative value of outstanding claims and the total amount of memory that has been allocated to the guest.

* xl: Implement XENMEM_claim_pages support via 'claim_mode' global configKonrad Rzeszutek Wilk2013-04-161-0/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* docs: flesh out xl.cfg documentation, correct typos, reorganizeMatt Wilson2012-09-141-230/+256
| | | | | | | | | | | | | | | | | | | | | | | | | Some highlights: * Correct some markup errors: Around line 663: '=item' outside of any '=over' Around line 671: You forgot a '=back' before '=head3' * Add documentation for msitranslate, power_mgnt, acpi_s3, aspi_s4, gfx_passthru, nomigrate, etc. * Reorganize items in "unclassified" sections like cpuid, gfx_passthru to where they belong * Correct link L<> references so they can be resolved within the document * Remove placeholders for deprecated options device_model and vif2 * Remove placeholder for "sched" and "node", as these are options for cpupool configuration. Perhaps cpupool configuration deserves a section in this document. * Rename "global" options to "general" * Add section headers to group general VM options.

* libxl/xl: implement support for guest ioport and irq permissions.Ian Campbell2012-09-031-0/+24
| | | | | | | | | | | | | | | | | | | | This is useful for passing legacy ISA devices (e.g. com ports, parallel ports) to guests. Supported syntax is as described in http://cmrg.fifthhorseman.net/wiki/xen#grantingaccesstoserialhardwaretoadomU I tested this using Xen's 'q' key handler which prints out the I/O port and IRQ ranges allowed for each domain. e.g.: (XEN) Rangesets belonging to domain 31: (XEN) I/O Ports { 2e8-2ef, 2f8-2ff } (XEN) Interrupts { 3, 5-6 } Signed-off-by: Ian Campbell <ian.campbell@citrix.com> Tested-by: Dieter Bloms <dieter@bloms.de> Acked-by: Ian Jackson <ian.jackson@eu.citrix.com> Committed-by: Ian Campbell <ian.campbell@citrix.com>
* libxl: add option to choose who executes hotplug scriptsRoger Pau Monne2012-07-261-0/+8
| | | | | | | | | | | | | | | | | Add and option to xl.conf file to decide if hotplug scripts are executed from the toolstack (xl) or from udev as it used to be in the past. This option is only introduced in this patch, but it has no effect since the code to call hotplug scripts from libxl is introduced in a latter patch. This choice will be saved in "libxl/disable_udev", as specified in the DISABLE_UDEV_PATH constant.

* libxl: enable automatic placement of guests on NUMA nodesDario Faggioli2012-07-261-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a domain does not have a VCPU affinity, try to pin it automatically to some PCPUs. This is done taking into account the NUMA characteristics of the host. In fact, we look for a combination of host's NUMA nodes with enough free memory and number of PCPUs for the new domain, and pin it to the VCPUs of those nodes. Deciding which placement is the best happens by means of some heuristics. For instance, smaller candidates are better, both from a domain perspective (less memory spreading among nodes) and from the entire system perspective (smaller memory fragmentation). In case of candidates of equal sizes (i.e., with the same number of nodes), the amount of free memory and the number of domains' vCPUs already pinned to the candidates' nodes are both considered. Very often, candidates with greater amount of memory are the one we wants, as this is good for keeping memory fragmentation under control. However, we do not want to overcommit some node too much, just because it has a lot of memory, and that's why the number of vCPUs must be accounted for. This all happens internally to libxl, and no API for driving the mechanism is provided for now. This matches what xend already does.

* xl: support empty CDROM devicesIan Campbell2012-07-261-9/+21
| | | | | | | | | | | | | | | | | | | | | | | | | The important change here is to xlu_disk_parse to correctly set format == EMPTY for CDROM devices which are empty. Test cases are added which check for correctness here. xend accepts ',hdc:cdrom,r'[0] as an empty CDROM drive however this is not consistent with the xl syntax in docs/misc/xl-disk-configuration.txt which requires ',,hdc:cdrom,r' (the additional positional paramter is the format). I'm not sure if/how this can be fixed. Note that xend does not accept ',,hdc:cdrom,r' There are several incidental cleanups included the the cdrom-{insert,eject} commands: - add a dry-run mode - use the non-deprecated disk specification syntax - check for and report errors from libxl_cdrom_insert [0] http://wiki.xen.org/wiki/CD_Rom_Support_in_Xen Signed-off-by: Ian Campbell <ian.campbell@citrix.com> Acked-by: Ian Jackson <ian.jackson@eu.citrix.com> Signed-off-by: Ian Jackson <ian.jackson@eu.citrix.com> Committed-by: Ian Campbell <ian.campbell@citrix.com>
* xl: rename "list-vm" command to "vm-list"Matt Wilson2012-06-291-0/+13
| | | | | | | | | | | | | | | All of the other "list" verbs are of the form "$noun-list". For example: "pci-list", "vcpu-list", "network-list", "block-list", etc. Additionally, many people have well trained muscle memory from years of typing "xm li". "xl li" was ambiguous due to "xl list-vm", thus resulting in "command not implemented". Finally, this command was missing from the xl man page.
