[Xen-devel] [PATCH v3 0/6] libxl: xs_restrict QEMU

[Stefano Stabellini <stefano.stabellini@xxxxxxxxxxxxx>]

Hi all,

this patch series changes libxl to start QEMU as device model with the
new xsrestrict option (http://marc.info/?l=xen-devel&m=143341692707358).
It also starts a second QEMU to provide PV backends in userspace (qdisk)
to HVM guests.


Changes in v3:
- use LIBXL_TOOLSTACK_DOMID instead of 0 in the commit message
- update commit message with more info on why it is safe
- add a limit on the number of physmap entries to save and restore
- add emulator_ids
- mark patch #3 as WIP
- use LIBXL_TOOLSTACK_DOMID instead of 0 in the commit message
- change xs path to include the emulator_id
- change qdisk-backend-pid path on xenstore
- use dcs->dmss.pvqemu to spawn the second QEMU
- keep track of the rc of both QEMUs before proceeding

be written by $DOMID
      libxl: do not add a vkb backend to hvm guests
      [WIP] libxl: xsrestrict QEMU
      libxl: change xs path for QEMU
      libxl: change qdisk-backend-pid path on xenstore
