* 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.

| | | | | | | | | | | | | While it seems obvious to initialize the UART before using it, chances are that some firmware code or the bootloader already did this. So it may actually be a good idea to skip the initialization, in fact this fixes early printk on my TC2 Versatile Express.

* libxl: postpone backend name resolutionDaniel De Graaf2013-04-171-0/+12
| | | | | | | | | | | | | | | | | | | | This adds a backend_domname field in libxl devices that contain a backend_domid field, allowing either a domid or a domain name to be specified in the configuration structures. The domain name is resolved into a domain ID in the _setdefault function when adding the device. This change allows the backend of the block devices to be specified (which previously required passing the libxl_ctx down into the block device parser), and will simplify specification of backend domains in other users of libxl. The check on run_hotplug_scripts in parse_config_data is removed because it is a duplicate of the one in libxl__device_nic_setdefault, and is removed here because it no longer has the resolved domain ID to check.

* 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.

* tools+stubdom: install under /usr/local by default.Ian Campbell2013-04-122-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | Now that the hotplug scripts have been fixed to remove hardcoded paths lets try this again. From 26470:acaf29203cf9: This is the defacto (or FHS mandated?) standard location for software built from source, in order to avoid clashing with packaged software which is installed under /usr/bin etc. I think there is benefit in having Xen's install behave more like the majority of other OSS software out there. The major downside here is in the transition from 4.2 to 4.3 where people who have built from source will innevitably discover breakage because 4.3 no longer overwrites stuff in /usr like it used to so they pickup old stale bits from /usr instead of new stuff from /usr/local. Packages will use ./configure --prefix=/usr or whatever helper macro their package manager gives them. I have confirmed that doing this results in the same list of installed files as before this patch was applied. The hypervisor remains in /boot/ and there is no intention to move it.

* libxl: pass debug flag down to libxl_domain_suspendOlaf Hering2013-02-151-0/+4
| | | | | | | | | | | | libxl_domain_suspend is already prepared to handle LIBXL_SUSPEND_DEBUG, and xl migrate handles the -d switch as well. Pass this flag down to libxl_domain_suspend, so that finally xc_domain_save can dump huge amount of debug data to stdout. Update xl.1 and help text output.

* docs: check for documentation generation tools in docs/configure.Ian Campbell2013-01-254-25/+69
| | | | | | | | | | | | | | | | | | | | | It is sometimes hard to discover all the optional tools that should be on a system to build all available Xen documentation. By checking for documentation generation tools at ./configure time and displaying a warning, Xen packagers will more easily learn about new optional build dependencies, like markdown, when they are introduced. Based on a patch by Matt Wilson. Changed to use a separate docs/configure which is called from the top-level in the same manner as stubdoms. Rerun autogen.sh and "git add docs/configure" after applying this patch.

| | | | | | | | | | | | | | This document is about an old unmaintained version of the XenAPI, which bears little to no relation to what is implemented in xapi and which is only partially implemented in xend (which is deprecated). The doc hasn't seen much in the way of updates since 2009. Anyone who is actually interested can continue to use the version which was in 4.2.

* xsm/flask: add distinct SIDs for self/target accessDaniel De Graaf2013-01-111-4/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Because the FLASK XSM module no longer checks IS_PRIV for remote domain accesses covered by XSM permissions, domains now have the ability to perform memory management and other functions on all domains that have the same type. While it is possible to prevent this by only creating one domain per type, this solution significantly limits the flexibility of the type system. This patch introduces a domain type transition to represent a domain that is operating on itself. In the example policy, this is demonstrated by creating a type with _self appended when declaring a domain type which will be used for reflexive operations. AVCs for a domain of type domU_t will look like the following: scontext=system_u:system_r:domU_t tcontext=system_u:system_r:domU_t_self This change also allows policy to distinguish between event channels a domain creates to itself and event channels created between domains of the same type. The IS_PRIV_FOR check used for device model domains is also no longer checked by FLASK; a similar transition is performed when the target is set and used when the device model accesses its target domain.
