i'm running kvm-83 wrapped around a linux-2.6.24 x86. i dont see vm exits for rdmsr or wrmsr on the sysenter msrs (0x174 - 0x176) but do for the range (0x200 - 0x2ff). it does *not* seem to involve the msr bitmap (it doesnt seem to matter whether the msr bitmap is set or not set, enabled or disabled); but is there any other execution, exit, or entry control that could account for this? (i've been pouring over Ch. 20 for days, but havent come up with anything).
