Hi All,
This is today's KVM test result against kvm.git
ff5bdac4be0230e0bb33e4208ac0a91343c72929 and kvm-userspace.git
eb2fd67cbecdb573f908697ed41b81ee312372bd.
sure hugetlb_fault() is called with the right write_access parameter.
Can you please upgrade your test hosts to 2.6.25 or newer?
I tried to test it against 2.6.25-rc5.
The host hanged while booting a xp guest.
Yunfeng,
Good news is that I can't reproduce the problem with kvm.tip as of
today. Both Win XP and Win 2000 Server boot happily (note: before those
fixes 2000 would crash complaining about PFN list corruption) and all of
their memory is mapped with 2MB pagetables.
Bad news is that I can't reproduce the problem at all anymore, so its
hard to pinpoint which change fixed it (assuming the bug is actually
fixed).
So, since there have been two important hugetlb fixes since
ff5bdac4be0230e0bb33e4208ac0a91343c72929, it would be good if you can
try a recent kvm.tip on the host.
I retested it against kvm.git d660add61a69df36372c73e68d2532190ca6430c.
It works well again.
thanks
Yunfeng
