2011-12-19configure: Improve Xen autodetection for hosts without XenStefan Weil1-4/+25
With this patch, it only takes one test (instead of four) to detect that there is no Xen support at all. For most build hosts, this will reduce the time configure needs. It will also reduce noisy output in config.log. Build hosts with Xen now need up to five (instead of up to four) tests. They get improved diagnostics when Xen support fails.

2011-12-10w32: QEMU applications with SDL are always GUI applicationsStefan Weil1-3/+0
Since commit 1d14ffa97eacd3cb722271eaf6f093038396eac4 (in 2005), QEMU applications on W32 don't use the default SDL compiler flags: Instead of a GUI application, a console application is created. This has disadvantages (there is always an empty console window) and no obvious reason, so this patch removes the strange flag modification. The SDL GUI applications still can be run from a console window and even send stdout and stderr to that console by setting environment variable SDL_STDIO_REDIRECT=no.

2011-12-06configure: Don't mix glib and libcheck testsLuiz Capitulino1-2/+3
test-coroutine is listed as a libcheck test in the 'checks' variable. This is not right because 'make check' won't run test-coroutine if libcheck tests are not enabled (either because libcheck isn't detected or because --disable-check-utests is passed). Tests using the glib test framework are independent from libcheck and afaik are always present (although having a configure switch to disable them is probably worth it). Untangle test-coroutine from the libcheck tests by introducing the 'test_progs' variable and using it to generate the test list used by 'make check'.

2011-11-21configure: build position independent executables on x86-Linux hostsAvi Kivity1-18/+47
Change the default on x86 Linux hosts to building PIE (position independent executables); instead of restricting the option to user-only targets, apply it to all targets. In addition, set the relocation sections to read-only (relro) when available; this reduces the attack surface by disallowing changes to relocation tables at runtime. While PIE reduces performance and relro increases load time, it greatly improves security, with the potential to reduce a code execution vulnerability to a self denial of service. Non-x86 are not changed, as they require TCG changes; neither are non-Linux, due to lack of test coverage.

2011-10-30PPC: Fail configure when libfdt is not availableAlexander Graf1-1/+10
We have several targets in the PPC tree now that basically require libfdt to function properly, namely the pseries and the e500 targets. This dependency will rather increase than decrease in the future, so I want to make sure that people building shiny new 1.0 actually have libfdt installed to get rid of a few ifdefs in the code. Warning: This patch will likely make configure fail for people who don't select their own --target-list, but don't have libfdt development packages installed. However, we really need this new dependency to move on. Signed-off-by: Alexander Graf <agraf@suse.de> --- v1 -> v2: - no paranthesis - no fdt check for config_pseries - add . in error message

2011-10-28iSCSI block driverRonnie Sahlberg1-0/+31
This provides built-in support for iSCSI to QEMU. This has the advantage that the iSCSI devices need not be made visible to the host, which is useful if you have very many virtual machines and very many iscsi devices. It also has the benefit that non-root users of QEMU can access iSCSI devices across the network without requiring root privilege on the host. This driver interfaces with the multiplatform posix library for iscsi initiator/client access to iscsi devices hosted at git://github.com/sahlberg/libiscsi.git The patch adds the driver to interface with the iscsi library. It also updated the configure script to * by default, probe is libiscsi is available and if so, build qemu against libiscsi. * --enable-libiscsi Force a build against libiscsi. If libiscsi is not available the build will fail. * --disable-libiscsi Do not link against libiscsi, even if it is available. When linked with libiscsi, qemu gains support to access iscsi resources such as disks and cdrom directly, without having to make the devices visible to the host. You can specify devices using a iscsi url of the form : iscsi://[<username>[:<password>@]]<host>[:<port]/<target-iqn-name>/<lun> When using authentication, the password can optionally be set with LIBISCSI_CHAP_PASSWORD="password" to avoid it showing up in the process list Signed-off-by: Ronnie Sahlberg <ronniesahlberg@gmail.com> Reviewed-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
