103 menu "Supported host OS features"
105 config MULTITHREAD_OS
106 bool "Host support for multiple threads"
109 Select this if your OS supports multiple threads of execution. This will enable features in Palacios
110 to require the creation of additional execution threads.
113 config ALIGNED_PG_ALLOC
114 bool "Host support for aligned page allocations"
117 Select this if your OS supports allocating memory pages using an alignment. This is required
118 if you want Palacios to run with large page table pages.
121 int "Maximum number of cpus"
125 Specifies the maximum number of hardware CPUs supported by the OS
126 For uniprocessor environments, set this to 1
130 source "palacios/src/interfaces/Kconfig"
134 bool "Enable VMM telemetry support"
137 Enable the telemetry framework in Palacios
139 This is a framwork that allows components of palacios to record
140 information that is periodically reported to the log output.
141 Telemetry is automatically collected for vmexits. Subsystem telemetry
142 is configured separately
145 config SHADOW_PAGING_TELEMETRY
146 bool "Enable Shadow Paging Telemetry"
150 Enable telemetry information for shadow paging
155 bool "Enable Experimental options"
158 This allows the selection of experimental features. This includes incomplete or unreviewed code.
159 Only enable this feature if you are working on the features in question.
160 IMPORTANT: Non-experimental code MUST NOT use, require, or rely on experimental features.
161 Any code that violates this will be immediately deleted without warning.
163 The purpose of this option is to allow features under development to be committed to the mainline
164 to more easily track changes and provide access to multiple developers
167 depends on EXPERIMENTAL
168 bool "Enable Vnet in Palacios"
171 Enable the Vnet in Palacios
175 bool "Enable VM inspection"

225 bool "Enable Time virtualization"
228 Enables the timer virtualization extensions
230 config TIME_HIDE_VM_COST
231 bool "Hide VMM Run Cost"
233 depends on VIRTUALIZE_TIME
235 Offset guest time from host time sufficiently to hide the cost of
236 running in the virtual machine. This can aid the consistency of
237 time between multiple timers, but can cause the guest to run
238 a good bit slower than the host in VM-intensive parts of the code.
240 config TIME_VIRTUALIZE_TSC
241 bool "Fully virtualize guest TSC"
243 depends on VIRTUALIZE_TIME
245 Virtualize the processor time stamp counter in the guest,
246 generally increasing consistency between various time sources
247 but also potentially making guest time run slower than real time.
