Your patch introduces a bug in mwait. Try my commited patch instead.

Currently HLT always traps at the IP after the hlt instruction. SVM
requires its trap on the instruction's IP though, which breaks the
current implementation as soon as an HLT intercept occurs.

This patch does the SVM intercept with an IP value before the HLT
