[libvirt] [PATCH 0/4] libxl: support SPICE graphics

by Jim Fehlig

This series provides support for SPICE graphics in the libxl driver. The first patch is mostly code movement. The second patch is a trivial name change of a structure member. Patch3 populates the libxl_domain_build_info struct with SPICE info. SPICE isn't as nice without QXL, so patch4 provides support for QXL video device. Jim Fehlig (4): libxl: populate build_info vfb in separate function libxl: change reservedVNCPorts to reservedGraphicsPorts libxl: support SPICE graphics for HVM … [View More]

[libvirt] [PATCH v2 0/3] storage: Fix problem with disk backend pool allocation calculation

That removes the need to add 1 for the extended partition leaving only the need to check for whether it's a refresh or create … [View More]
