This patch enables IO bitmaps control on vmx and unmask the 0x80 port to
avoid VMEXITs caused by accessing port 0x80. 0x80 is used as delays (see
include/asm/io.h), and handling VMEXITs on its access is unnecessary but
slows things down. This patch improves kernel build test at around
3%~5%.
Hi,
First I tried kvm build into the kernel, 2.6.21, togeather with kvm-17,
no problem at all, except that qemu shuts down when I do a reboot in the
guest os. Is there any fix for that btw, guest os is Linux Slackware
11.0 with kernel 2.6.21?
After that I tried upgrading to kvm-21, removing kv
Hi all,
I met some problem : when I create only one svm guest, the qemu hangs
with caption "QEMU/KVM[Stopped]". And this guest can't run any longer. If I
create more than 1 svm guest, the guest are running normally except the 1st
one(qemu stopped). There's no special error log, including serial
O, my fault! Sorry.

Looking at following code, PT_INDEX is defined as a host environment
dependant MACRO while the code is walking guest page table. Is this a
bug? Do we ever get a pure 32 bits (non PAE) guest run on top of 64 bits
(or PAE) host?
thanks,eddie
static int FNAME(walk_addr)(struct guest_walker *walker,
Third time's a charm, right? :-)

It might have worked in this case since PT_PRESENT_MASK is 1, but let's
express this correctly.
