* Fix ia64 tools buildKeir Fraser2010-11-021-0/+46
| | | | | | | | | | | 22066:eccfdeb41b80 replaced tools/libxc/ia64/aclinux.h with xen/include/acpi/platform/aclinux.h. Because both are incompatible, tools cannot be built on ia64. This patch fixes compilation errors by defining identifiers at ac_ia64_tools.h. Signed-off-by: KUWAMURA Shin'ya <kuwa@jp.fujitsu.com>

* hvmloader: Configure gPXE to use serial consoleKeir Fraser2010-10-291-0/+3
| | | | | | | | Sometimes we would rather connect to an HVM's serial console than it's VGA display. In this case we cannot see or interact with the ethernet booting process. This is a bit annoying so let's just enable it. Signed-off-by: Gianni Tedesco <gianni.tedesco@citrix.com>
* avoid numa placement of cpus with active cpupoolsJuergen Gross2010-10-282-1/+6
| | | | | | | | | When using cpupools don't pin vcpus to numa nodes as this might conflict with the cpupool definition. numa placement should be handled by cpupool configuration instead.

* libxl: Fix migration of HVM guestsIan Campbell2010-10-285-10/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | In the default "QemuDeviceModelRecord"-style HVM tail of the migration protocol the size of the qemu save record is unknown at the receiver and therefore it must read until EOF. This is not compatible with the xl migration protocol which contains a post-migration handshake and therefore cannot close the socket on the sending end. What is required is an explicit length field for the save record, which the "RemusDeviceModelState"-style HVM tail includes. Rather than overload the "RemusDeviceModelState" name for a non-Remus use case (on off chance that they need to diverge for some reason in the future) introduce a third style called "DeviceModelRecord0002" which is identical to current "RemusDeviceModelState"-style. Hopefully the inclusion of a number here will allow easier extension in the future without needing to come up with increasingly less helpful names! Also propagate errors from xc_domain_save and libxl__domain_suspend_common to callers. Signed-off-by: Ian Campbell <ian.campbell@citrix.com> Signed-off-by: Ian Jackson <ian.jackson@eu.citrix.com>

* libxl: Fix format string abuses / vulnerabilitiesIan Jackson2010-10-281-5/+8
| | | | | | | | | | | | | | | | | There are a few places where libxl__xs_write is passed a variable value to write to xenstore, but the semantics are that the first char* is a format string. So use "%s". This fixes the following errors reported by some newer compilers: libxl.c: In function "libxl_create_cpupool": libxl.c:3981: error: format not a string literal and no format arguments libxl.c:3983: error: format not a string literal and no format arguments libxl.c: In function "libxl_cpupool_movedomain": libxl.c:4095: error: format not a string literal and no format arguments Signed-off-by: Ian Jackson <ian.jackson@eu.citrix.com> Acked-by: Ian Campbell <ian.campbell@citrix.com> Acked-by: Gianni Tedesco <gianni.tedesco@citrix.com>
* libxl: fix dom0 minimum memory threshold checkGianni Tedesco2010-10-281-6/+7
| | | | | | | | | | | | | | libxl_set_memory_target tries to set the memory target for a given domain to new_target_memkb. The function includes a check to make sure that dom0's memory is not reduced below a minimal threshold ie. LIBXL_MIN_DOM0_MEM. However, this check is performed before the new_target_memkb variable is properly initialised - when the value is always zero. This means that the check always fails. Fix this by moving the test to happen after the proper initialisation of new_target_memkb.

* gdbsx: Makefiles: correctly generate dependenciesGianni Tedesco2010-10-283-7/+2
| | | | | | | | | | | gdbsx hacks CFLAGS to remove optimisations for easier debugging, however this breaks dep generation due to an early evaluation of CFLAGS and leaves stale files called "..d" after a make clean. We could possibly fix this by separating dep generation from the rest of CFLAGS but it seems a little invasive. The gdbsx hackers can do their own thing during development and testing anyway...

* Do not wait for memory teardown when live migrateMiroslav Rezanina2010-10-282-21/+30
| | | | | | | | | | When trying to live migrate guest with great memory (e.g. 20 GB), there's delay caused by destroying source copy of domain. To speed up this process we can close socket before starting guest destroy, as source guest is not running anymore.

| * "kdd" Windows debugger stub.Tim Deegan2010-10-265-0/+2223
| | | | | | | | | | | | | | | | | | | | | | | | kdd runs in dom0, attaches to a domain and speaks the Windows kd serial protocol over a TCP connection (which should go to kd or windbg, e.g. by having another VM with its virtual COM1 set up as a TCP listener). It doesn't do breakpoints &c yet, and windbg can get quite confused since the kernel debugger's not actually running, but it's good enough to extract backtraces from wedged VMs. Signed-off-by: Tim Deegan <Tim.Deegan@citrix.com>

* | libxc: do not align/lock buffers which do not need itIan Campbell2010-10-222-24/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On restore: region_mfn is passed to xc_map_foreign_range and xc_map_foreign_bulk. In both cases the buffer is accessed from the ioctl handler in the kernel and not from any hypercall. Therefore normal copy_{to,from}_user handling in the kernel will cope with any faulting access. p2m_batch is passed to xc_domain_memory_populate_physmap which takes care of bouncing the buffer already. On save: pfn_type is passed to xc_map_foreign_bulk which does not need locking as per region_mfn above.
