* stubdom: 'file' based disk sharingKeir Fraser2009-05-261-3/+3
| | | | | | | | | | Allow 'file' based disks, that are blkback based disks, to be shared between the guest domain and the stubdom. It does so exploiting the same exception introduced in the previous patch "stubdoms phy disks sharing". Now we can remove the hack in stubdom-dm that forces "file" disks to be opened using blktap instead of blkback. Signed-off-by: Stefano Stabellini <stefano.stabellini@eu.citrix.com>

* xend: Make hotplug script timeouts configurableKeir Fraser2009-05-193-2/+26
| | | | | | | | | | | | | | In some configurations, when dom0 is busy with I/O, it may take several minutes to complete all hotplug scripts required when a new domain is being created. As device create timeout is set to 100 seconds, users get "hotplug scripts not working" error instead of a new domain. This patch makes both DEVICE_CREATE_TIMEOUT and DEVICE_DESTROY_TIMEOUT configurable in xend-config.sxp to allow users to easily adapt hotplug timeouts to their environment.

Of course, using xm block-detach and xm block-attach instead of xm block-configure, we can change it. However, I'd like to change it by using xm block-configure.

* passthrough: Fix PCI hot-plug option parsingKeir Fraser2009-05-131-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a PCI function is passed-through extra options may be passed through. In the case of boot-time PCI pass-through the documented format is: [dom:]bus:dev.slot[@vslot][[,opt]...] e.g. 00:01.00.1@7,msitranslate=3D1 In the case of PCI hot-plug the xm pci-attach command take the following arguments: [-o opt[,opt]...] [dom:]bus:dev.slot [vslot] e.g. -o msitranslate=3D1 00:01.00.1 7 These xm ends up passing these to xem-qemu as: [dom:]bus:dev.slot[[,opt]...][@vslot] e.g. 00:01.00.1,msitranslate=3D1@7 Note that the option and the vslot have are transposed when compared to the format used by boot-time PCI pass-through. The parser inside qemu-xen can only handle the format used by boot-time PCI pass-through and because of this ignores any options passed by hot-plug. This patch alters format used by hot-plug to match the parser. Signed-off-by: Simon Horman <horms@verge.net.au>

* Permit user to suppress passing --prefix to setup.pyKeir Fraser2009-05-073-9/+9
| | | | | | | | | | | | | | | | | | | | | | | | | We change all invocations of setup.py as follows: * use $(PYTHON) instead of `python' so that the user can specify an alternative python version if they need to. If not set it defaults to `python' in Config.mk. * pass --prefix=$(PREFIX) via a new make variable $(PYTHON_PREFIX_ARG). This allows a user to suppress the --prefix=... argument entirely by setting PYTHON_PREFIX_ARG=''. This will work around the bug described here https://bugs.launchpad.net/ubuntu/+bug/362570 where passing --prefix=/usr/local (which ought to have no effect as /usr/local is the default prefix) changes which subdirectory distutils chooses, and results in the files being installed in site-packages which is not on the default search path. Users not affected by this python packaging bug should not set PYTHON_PREFIX_ARG and their builds will not be affected. (Provided PREFIX did not contain spaces. People who put spaces in PREFIX are being quite optimistic.) Signed-off-by: Ian Jackson <ian.jackson@eu.citrix.com>

* xend: Fix for op_pincpu in SrvDomain.pyKeir Fraser2009-04-273-5/+4
| | | | | | | | | | | | | | | | | | | | | op_pincpu method in SrvDomain.py does not currently work because op_pincpu method gives string objects to a cpumap argument of domain_pincpu method in XendDomain.py though the cpumap argument expects list objects. This patch solves the above problem as follows. op_pincpu method gives string objects to the cpumap argument as is, because op_pincpu method cannot give list objects to the cpumap argument. Instead, domain_pincpu method expects that the cpumap argument is string objects, then domain_pincpu method converts the cpumap argument into list objects. Also, the patch modifies two methods (except for op_pincpu method) calling domain_pincpu method. The methods give string objects to the cpumap argument instead of list objects.

* xm: Fix hot-unplug of statically-assigned devicesKeir Fraser2009-04-233-5/+6
| | | | | | | | | | | | | | | | | | | | | | Prior to changset 19510:5c69f98c348e - 'xm, xend: Replace "vslt" with "vslot"', both vslt and vslot were used in the xm code, often fairly arbitrarily. However, in the dictionary that describes a pci function both vslt and vslot were present. vslt stored the slot assigned to the function. And vslot stored the slot the user requested for the function, or AUTO_PHP_SLOT if no slot was requested. With the renaming these two values got merged into a single entry. This patch un-merges them by renaming the what was vslot to requested_vslot. So an out of chronological order list of name changes is: 'vslot' -> 'requested_vslot' 'vslt' -> 'vslot' Signed-off-by: Simon Horman <horms@verge.net.au>
* xend: Do not overwrite xauthority and display with empty valuesKeir Fraser2009-04-231-2/+2
| | | | | | | | | | | | Display and xauthority vars are read from vmConfig['platform'] first, then they are read again from dev_info. However if the user does not set those variable in the config file, dev_info won't contain them, hence we are going to overwrite the current significant values with null. This patch fixes the problem setting display and xauthority to the current values if dev_info does not contain them. Signed-off-by: Stefano Stabellini <stefano.stabellini@eu.citrix.com>
* stubdoms: generate stubdom config fileKeir Fraser2009-04-231-1/+6
| | | | | | | | | | | | | | | | | | This patch removes the need for a second configuration file for stubdoms: it is going to be automatically generated by the script stubdom-dm using command line options and xenstore to find any needed information. The configuration script will be placed under /etc/xen/stubdoms and automatically removed when the domain is destroyed. The only change needed in xend is not to write on xenstore sdl, opengl and serial command line options for qemu, because stubdoms do not support them. It is safe to remove those two options from xenstore because qemu does not use xenstore to read commans line options. Finally this patch fixes blkfront disconnections from backends and display and xauthority variables for pv guests. Signed-off-by: Stefano Stabellini <stefano.stabellini@eu.citrix.com>

There is already a logic to avoid too early restarting, however, it might not work. Since xenstore entry 'xend/previous_restart_time' is volatile. XendDomainInfo.destroy() which removes the entry from xenstore is called in some places. Also, this patch prevents too early restarting even at the first domain creation.

* tools: dom0 iptables rule ordering changeKeir Fraser2009-04-141-6/+9
| | | | | | | | | | | | | | | | | | | This patch makes two small changes to dom0 iptables rules that permit (and revoke) domU network access. First: Currently, a rule intended to allow domU network access is appended to the end of the FORWARD chain, where it can be preempted by other =20 rules. This patch causes the rule to be inserted at the top, where it's more likely to have the intended effect. Second: In some cases (e.g. Fedora 9's default iptables configuration), the first rule alone is insufficient to permit two-way packet flow. This patch adds a second rule to the FORWARD chain that permits replies to domU network requests to reach the domU vif. Signed-off-by: Chris Bookholt <hap10@tycho.ncsc.mil>

* tools: Always use sane upstream (`native') python pathsKeir Fraser2009-04-0817-89/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, by default we would install our python modules into /usr/lib/python/xen, for example /usr/lib/python/xen/__init__.py. Upstream python's standard install location (a) includes the Python version number and (b) puts things in site-packages by default. Our best conjecture for the reason for this was an attempt to make the installs portable between different python versions. However, that doesn't work because compiled python modules (.pyc), and C python extensions corresponding to one version of python, are not compatible across different versions of python. This is why upstream include the version number. site-packages is the standard location for locally-installed packages and is automatically included on the python search path. In this change, we abandon our own unusual python path setup: * Invoke setup.py in an entirely standard manner. We pass PREFIX and DESTDIR using the appropriate options provided by setup.py for those purposes (adding them to setup.py calls which were previously lacking them). * Since the installation locations are now on the standard python path, we no longer need to add anything to the path in any of our python utilities. Therefore remove all that code from every python script. (Many of these scripts unconditionally added /usr/lib/python and /usr/lib64/python which is wrong even in the old world.) * There is no longer any special `Xen python path'. xen-python-path is no longer needed. It is no longer called by anything in our tree. However since out-of-tree callers may still invoke it, we retain it. It now prints a fixed string referring to a directory which does not to exist; callers (who use it to augment their python path) will thus add a nonexistent directory to their python path which is harmless. * Remove various workarounds including use of setup.py --home (which is intended for something completely different). * Remove tests for the XEN_PYTHON_NATIVE_INSTALL build-time environment variable. The new behaviour is the behaviour which we should have had if this variable had been set. That is, it is now as if this variable was always set but also bugs in the resulting install have been fixed. This should be a proper fix for the bug addressed by c/s 19515.
