| Thread-topic: | [Patch] Add NMI Injection and Pending Support in VMX |
Currently, Xen does not support injecting an NMI to HVM guest OS. Adding this feature is necessary for those softwares which depend on NMI to function correctly, such as KDB and oprofile. The attached patch allows NMI to be injected to guest OS in NMIP capable platforms. It also enables to queue an NMI and then inject it as soon as possible.
