* Fix vcpu hotplug bug: transfer vcpu_avail hex string to qemuKeir Fraser2010-03-201-1/+1
| | | | | | | | | | | | | | | Currently qemu has a bug: When maxvcpus > 64, qemu will get wrong vcpu bitmap (s->cpus_sts[i]) since it only get bitmap from a long variable. This patch, cooperate with another qemu patch, is to fix this bug. This patch transfer a vcpu_avail string in a hex string format, so that at qemu side it's more easier to get vcpu bitmap from hex string, especially when many vcpus, like more than 64. (Also update QEMU_TAG for matching qemu-side update) Signed-off-by: Liu, Jinsong <jinsong.liu@intel.com>

| | | | | | | | There are more than 64 cpus on new intel platform especially on NUMA system, so that we need break the pcpu limit (that is 64) when set affinity of a VCPU. Signed-off-by: James (song wei) <jsong@novell.com>
* Increase default console ring allocation size and reduce default verbosityKeir Fraser2010-03-171-4/+29
| | | | | | | | | | | | | | | | | | | | In order to have better chance that relevant messages fit into the ring buffer, allocate a dynamic (larger) one in more cases, and make the default allocation size depend on both the number of CPUs and the log level. Also free the static buffer if a dynamic one was obtained. In order for "xm dmesg" to retrieve larger buffers, eliminate pyxc_readconsolering()'s 32k limitation resulting from the use of a statically allocated buffer. Finally, suppress on x86 most per-CPU boot time messages (by default, most of them can be re-enabled with a new command line option "cpuinfo", some others are now only printed more than once when there are inconsistencies between CPUs). This reduces both boot time (namely when a graphical console is in use) and pressure on the console ring and serial transmit buffers. Signed-off-by: Jan Beulich <jbeulich@novell.com>

* blktap/fs-back: Build fixes for Fedora 13Keir Fraser2010-03-157-2/+7
| | | | | | | | | | | | | 1. Some files use stat, mkfifo, mkdir etc. without including sys/stat.h 2. Some programs link against libpthread without a -lpthread compile option. The compile used to work if this library happened to be used by one of the other libraries that was being linked against, but Fedora 13 has stopped allowing this.

* libxenlight: fix segfault when domid_to_name returns NULLKeir Fraser2010-03-151-3/+3
| | | | | | | | | | | | | The function libxl_domid_to_name() can return NULL if the path /local/domain/%d/name does not exist. This causes a segfault if the NULL name is later passed as a value to libxl_xs_writev(). I'm hitting this making a call to libxl_device_vfb_add() from my graphical switcher application. This patch modifies xs_writev() and libxl_xs_writev() to skip NULL values. Signed-off-by: Eamon Walsh <ewalsh@tycho.nsa.gov>
* hotplug: Avoid race condition when creating or destroying network bridgesKeir Fraser2010-03-151-0/+10
| | | | | | | | | | | | | | | I saw the following message when I created or destroyed two bridges by using network-bridge script at same time. Of course names of the bridges are different. But, a temporal name "tmpbridge" is used by the script to create or destroy the bridges. I think that the message was shown by "tmpbridge".

* Fix Makefile targets that generate several files at onceKeir Fraser2010-03-052-4/+8
| | | | | | | | | | | | | | | | | | | | In a few places in the tree the Makefiles have constructs like this: one_file another_file: $(COMMAND_WHICH_GENERATES_BOTH_AT_ONCE) This is wrong, because make will run _two copies_ of the same command at once. This generally causes races and hard-to-reproduce build failures. Notably, `make -j4' at the top level will build stubdom libxc twice simultaneously! In this patch we replace the occurrences of this construct with the correct idiom: one_file: another_file another_file: $(COMMAND_WHICH_GENERATES_BOTH_AT_ONCE) Signed-off-by: Ian Jackson <ian.jackson@eu.citrix.com>

* Fix domain exit actions that contain hyphenKeir Fraser2010-03-031-4/+4
| | | | | | | | | | | | | | | Domain exit actions that contain a hyphen (e.g. rename-restart) were not being detected properly when xm is configured to use xenapi. Domain config containing on_crash=3D"rename-restart" results in xen53:~ # xm new /tmp/domU.config Using config file "/tmp/domU.config".

* Replace config file parser for "xl"Keir Fraser2010-03-038-129/+696
| | | | | | | | | | | | | | | | | | | | | | | | | | | This provides a replacement config file parser for "xl" based on bison and flex. Benefits: * proper error reporting with line numbers * parser can understand nearly all "xm" configuration files directly (doesn't understand Python code but should do everything else) * parser also understands the ;-infested "xl" style files * removes the dependency on libconfig * better checking for certain kinds of mistakes * eliminates the strange "massage file and try again" code This is intended to support all config files currently supported by "xl" and almost all files supported by "xm". (NB that whether a feature works depends on the implementation of that feature in xl/libxl of course.) This patch also introduces a new library "libxlutil" which is mainly for the benefit of "xl". Users of libxl do not need to use libxlutil, but they can do so if they want to parse "xl" files without being "xl".

* xend: notify xenpv device model that console info is readyKeir Fraser2010-02-241-0/+5
| | | | | | | | | | | | | | | | | | | | | | Sometimes PV domain with vfb doesn't boot up. /sbin/kudzu is stuck. After investigation, I've found that the evtchn for console is not bound at all. Normal sequence of evtchn initialization in qemu-dm for xenpv is: 1) watch xenstore backpath (/local/domain/0/backend/console/<domid>/0) 2) read console info (/local/domain/<domid>/console/{type, ring-ref, port..= }) 3) bind the evtchn to the port. But in some case, xend writes to the backpath before the console info is prepared, and never write to the backpath again. So the qemu-dm fails at 2) and never reach to 3). When this happens, manually xenstore-write command on Domain-0 resumes the guest. Signed-off-by: Kouya Shimura <kouya@jp.fujitsu.com>
