54 bool "Intel VMX Support"
57 Compile with support for Intel VMX
60 menu "Supported host OS features"
63 bool "Host support for multiple threads"
66 Select this if your OS supports multiple threads of execution. This will enable features in Palacios
67 to require the creation of additional execution threads.
70 config ALIGNED_PG_ALLOC
71 bool "Host support for aligned page allocations"
74 Select this if your OS supports allocating memory pages using an alignment. This is required
75 if you want Palacios to run with large page table pages.
78 int "Maximum number of cpus"
82 Specifies the maximum number of hardware CPUs supported by the OS
83 For uniprocessor environments, set this to 1
86 bool "Host Support for file operations"
89 Select this if your host OS supports file operatoins and you want Palacios to be able to use them.
93 bool "Host Support for VM console"
96 Select this if you want to forward a guest console interface to some host OS service
100 bool "Host support for Network Sockets"
103 Select this if you host OS implements a socket API that is available to Palacios. This is required
104 to support the internal networking features of Palacios.
111 bool "Enable VMM telemetry support"
114 Enable the telemetry framework in Palacios
116 This is a framwork that allows components of palacios to record
117 information that is periodically reported to the log output.
118 Telemetry is automatically collected for vmexits. Subsystem telemetry
119 is configured separately
122 config SHADOW_PAGING_TELEMETRY
123 bool "Enable Shadow Paging Telemetry"
127 Enable telemetry information for shadow paging
130 config INSTRUMENT_VMM
131 bool "Enable VMM instrumentation"
134 Enable the instrumentation framework
136 This is much heavier weight than profiling
139 bool "Enable Experimental options"
142 This allows the selection of experimental features. This includes incomplete or unreviewed code.
143 Only enable this feature if you are working on the features in question.
144 IMPORTANT: Non-experimental code MUST NOT use, require, or rely on experimental features.
145 Any code that violates this will be immediately deleted without warning.
147 The purpose of this option is to allow features under development to be committed to the mainline
148 to more easily track changes and provide access to multiple developers
