2016-09-29xenpv: Fix qemu_uuid compiling errorFam Zheng
9c5ce8db2 switched the type of qemu_uuid and this should have followed. Fix it. Signed-off-by: Fam Zheng <famz@redhat.com> Message-Id: <1474968011-29382-1-git-send-email-famz@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com> Acked-by: Stefano Stabellini <sstabellini@kernel.org>
2016-09-23vl: Switch qemu_uuid to QemuUUIDFam Zheng
Update all qemu_uuid users as well, especially get rid of the duplicated low level g_strdup_printf, sscanf and snprintf calls with QEMU UUID API. Since qemu_uuid_parse is quite tangled with qemu_uuid, its switching to QemuUUID is done here too to keep everything in sync and avoid code churn.

2016-08-03xen: use a common function for pv and hvm guest backend register callsJuergen Gross
Instead of calling xen_be_register() for each supported backend type for hvm and pv guests in their machine init functions use a common function in order not to have to add new backends twice. This at once fixes the error that hvm domains couldn't use the qusb backend.

2016-06-22xen: move xen_sysdev to xen_backend.cJuergen Gross
Commit 9432e53a5bc88681b2d3aec4dac9db07c5476d1b added xen_sysdev as a system device to serve as an anchor for removable virtual buses. This introduced a build failure for non-x86 builds with CONFIG_XEN_BACKEND set, as xen_sysdev was defined in a x86 specific file while being consumed in an architecture independent source. Move the xen_sysdev definition and initialization to xen_backend.c to avoid the build failure.

2016-05-23xen: add pvUSB backendJuergen Gross
Add a backend for para-virtualized USB devices for xen domains. The backend is using host-libusb to forward USB requests from a domain via libusb to the real device(s) passed through.

2016-05-23xen: introduce dummy system deviceJuergen Gross
Introduce a new dummy system device serving as parent for virtual buses. This will enable new pv backends to introduce virtual buses which are removable again opposed to system buses which are meant to stay once added.

2016-01-26xen: make it possible to build without the Xen PV domain builderIan Campbell
Until the previous patch this relied on xc_fd(), which was only implemented for Xen 4.0 and earlier. Given this wasn't working since Xen 4.0 I have marked this as disabled by default. Removing this support drops the use of a bunch of symbols from libxenctrl, specifically: - xc_domain_create - xc_domain_destroy - xc_domain_getinfo - xc_domain_max_vcpus - xc_domain_setmaxmem - xc_domain_unpause - xc_evtchn_alloc_unbound - xc_linux_build This is another step towards only using Xen libraries which provide a stable inteface.

2016-01-26xen: domainbuild: reopen libxenctrl interface after forking for domain watcher.Ian Campbell
Using an existing libxenctrl handle after a fork was never particularly safe (especially if foreign mappings existed at the time of the fork) and the xc fd has been unavailable for many releases. Reopen the handle after fork and therefore do away with xc_fd().

2015-11-13xen: fix usage of xc_domain_create in domain builderRoger Pau Monne
Due to the addition of HVMlite and the requirement to always provide a valid xc_domain_configuration_t, xc_domain_create now always takes an arch domain config, which can be NULL in order to mimic previous behaviour. Add a small stub called xen_domain_create that encapsulates the correct call to xc_domain_create depending on the libxc version detected.

2014-10-20hw: Convert from BlockDriverState to BlockBackend, mostlyMarkus Armbruster
Device models should access their block backends only through the block-backend.h API. Convert them, and drop direct includes of inappropriate headers. Just four uses of BlockDriverState are left: * The Xen paravirtual block device backend (xen_disk.c) opens images itself when set up via xenbus, bypassing blockdev.c. I figure it should go through qmp_blockdev_add() instead. * Device model "usb-storage" prompts for keys. No other device model does, and this one probably shouldn't do it, either. * ide_issue_trim_cb() uses bdrv_aio_discard() instead of blk_aio_discard() because it fishes its backend out of a BlockAIOCB, which has only the BlockDriverState. * PC87312State has an unused BlockDriverState[] member. The next two commits take care of the latter two. Signed-off-by: Markus Armbruster <armbru@redhat.com> Reviewed-by: Max Reitz <mreitz@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
